Quality Control and Testing Laboratory
Quality control and testing is a technical service that INFINITIA applies to objectively evaluate the quality, performance, and durability of materials, components, and industrial products. It allows verification of compliance, identification of deviations, and detection of potential defects before they result in production failures, product issues, or market claims.
In our quality control testing laboratory, advanced characterization techniques, physicochemical analysis, and experimental testing are combined to study everything from the composition and microstructure of materials to their response under real operating conditions. This approach makes it possible to analyze how variables such as design, manufacturing processes, environmental conditions, or end-use affect product performance through the execution of the necessary tests.
The objective is to provide data-driven technical information that enables material validation, design optimization, and assurance of product quality throughout its lifecycle using appropriate procedures and methods. This service is particularly relevant in industrial environments where functionality, safety, and durability must be guaranteed, and where decision-making requires experimental evidence rather than assumptions.
What is quality control and testing in industrial products?
Quality control and testing is a structured technical process aimed at objectively evaluating the behavior, composition, and durability of materials, components, and industrial products. Its purpose is not only to verify compliance with specifications but also to obtain experimental data that helps understand how a product performs under real or simulated conditions.
This approach allows identification of deviations, defects, or limitations before they become critical issues. In industrial practice, it is essential for validating materials, ensuring manufacturing quality, and guaranteeing that the product meets requirements in terms of functionality, safety, and service life.
From the perspective of forensic engineering applied to material quality control, it is necessary to analyze the product within its full context, including testing in an analysis laboratory. This involves studying its composition, structure, and properties, as well as its behavior under mechanical, thermal, chemical, or environmental stimuli using techniques such as material characterization, physicochemical analysis, or lifetime testing.
At INFINITIA, quality control and industrial laboratory testing are approached as tools for validation and continuous improvement. They enable the detection of errors, optimization of product performance, and anticipation of behavior over time, facilitating data-driven technical decision-making and reducing risks in demanding industrial environments.
Problems addressed by quality management in material durability and reliability
The absence of a robust quality control system in industrial processes prevents early detection of errors, causing latent defects to appear during service as failures, claims, or additional costs. In many cases, these issues are not evident during manufacturing but ultimately affect product reliability and operational efficiency. This situation forces reactive actions with ineffective solutions that do not address the root cause.
Industrial laboratory testing allows identification of deviations in critical properties such as mechanical strength, chemical behavior, or thermal stability, even when materials appear compliant. Without this analysis, premature degradation, incompatibilities between components, or loss of functionality often occur unexpectedly. These problems directly impact final quality and process repeatability.
Another critical issue is the lack of information about product durability. Without lifetime testing, it is difficult to predict how materials will evolve under real conditions, limiting the ability to define maintenance strategies, ensure long-term performance, or prevent failures in service. This uncertainty affects both design and product validation.
In sensitive sectors such as food, the absence of physicochemical or microbiological analysis can compromise product safety and generate regulatory risks. In general, the lack of characterization and testing prevents understanding material behavior under real conditions, making decision-making more difficult and increasing technical risk. In this context, quality control becomes a critical element rather than a simple verification step.
Quality control in INFINITIA testing laboratory. Physical, chemical and lifetime testing
Quality control and testing are approached from a technical perspective aimed at transforming uncertainty into actionable knowledge. In industrial environments, where decisions must be data-driven, this approach allows validation of hypotheses, comparison of alternatives, and anticipation of material and product behavior under real service conditions.
To achieve this, physical and chemical material testing is used to analyze composition, structure, and properties. These techniques provide key information on how materials respond under different conditions and are essential in both development and production phases to ensure consistency, compliance, and reliability.
This approach is complemented by the integration of lifetime testing and techniques such as accelerated aging, which allow estimation of product durability and evaluation of performance over time. This makes it possible to prevent failures, optimize designs, and reduce costs associated with maintenance or service incidents.
At INFINITIA, quality control is considered a comprehensive process that goes beyond data acquisition, focusing on technical interpretation for decision-making. This includes material validation, deviation identification, and compliance with current regulations, especially in regulated sectors where quality, safety, and compliance are critical.
Applications of quality control and testing to evaluate materials, processes, and final products
Quality control and testing cover multiple applications aimed at understanding material behavior and ensuring product quality at all stages through testing performed in a testing laboratory. From initial material analysis to validation under real conditions, these tests provide critical information for decision-making in quality control environments.
At INFINITIA, these applications are developed through a combination of advanced laboratory techniques and industrial expertise, adapting each analysis to the type of product and its conditions of use.
Material quality control through advanced characterization
These analyses allow detailed study of the physical, chemical, and mechanical properties of materials to understand their behavior and suitability for a specific application. Aspects such as structure, composition, strength, and stability under different conditions are evaluated using characterization techniques adapted to the type of material, whether metallic, polymeric, ceramic, or multimaterial.
At INFINITIA, material characterization is applied to determine how variables such as processing, formulation, or environmental conditions influence performance. This enables comparison of materials, validation of specifications, and detection of deviations between batches or suppliers, providing a solid technical basis for decision-making in design and production.
Additionally, characterization allows estimation of product lifetime and anticipation of degradation mechanisms, facilitating material optimization and improving final product reliability under real service conditions.
Lifetime testing for durability evaluation in industrial products
Lifetime testing allows evaluation of how materials and products evolve over time under controlled or accelerated conditions. Phenomena such as aging, degradation, fatigue, or loss of properties are analyzed by reproducing real-use conditions in the laboratory using variables such as temperature, humidity, radiation, or chemical exposure.
At INFINITIA, these tests are developed to control material and component durability, identifying critical points and anticipating failures before they occur in service. This approach enables the definition of maintenance cycles, validation of lifetime requirements, and comparison of alternative solutions in terms of long-term performance.
These studies are also essential during development and validation phases, as they allow optimization of product design, reduction of uncertainty, and minimization of costs associated with premature failures or market claims.
Design of experimental setups and custom testing for material and product validation
Custom testing enables the design of specific experimental configurations to reproduce real operating conditions or critical scenarios that cannot be evaluated using standardized methods. Through tailored setups, it is possible to analyze the behavior of materials, components, or systems under combinations of variables such as load, temperature, chemical agents, usage cycles, or complex environmental conditions.
At INFINITIA, customized laboratory tests are developed for each case, defining experimental protocols that allow hypothesis validation, identification of critical points, and reproduction of failures under controlled conditions. This approach is particularly useful when existing standards do not address the real problem or when specific application conditions must be evaluated.
Additionally, custom test setups enable comparison of solutions, material optimization, and validation of design decisions based on experimental evidence. These studies are key during development, industrialization, or product improvement phases, as they reduce uncertainty, anticipate risks, and support informed technical decisions.
Analysis of materials under mechanical, thermal, and chemical stimuli through the analysis laboratory
Industrial material analysis makes it possible to study how materials respond to different mechanical, thermal, chemical, or environmental stimuli, identifying the relevant tests and evaluations. This includes tests such as corrosion resistance, salt spray testing, exposure and resistance to chemical agents, thermal variations, abrasion wear, and other methods used to assess material behavior under demanding conditions.
At INFINITIA, we apply these analyses to understand the interaction between material and environment, identifying potential degradation mechanisms or incompatibilities. This is particularly relevant in applications where materials are exposed to aggressive or variable conditions that may affect their performance.
This approach makes it possible to validate the suitability of the material for its final application, optimize its selection, and prevent in-service problems, reducing technical risks and improving product durability.
Physicochemical analysis for identification and composition control
Physicochemical analysis makes it possible to identify the composition, structure, and characteristics of materials, including polymers, metals, coatings, and composite materials. Advanced techniques such as microscopy, spectroscopy, or chemical analysis are used to obtain detailed information about the components and their distribution.
At INFINITIA, we apply this type of analysis to validate formulations, detect contaminants, identify unknown materials, evaluate the quality of products and raw materials, and even detect counterfeits. This approach is key to ensuring conformity and understanding material behavior from a chemical and structural perspective.
These studies also make it possible to develop new materials, optimize compositions, and ensure product quality in sectors where composition is a critical factor for performance.
Environmental and UV radiation testing in materials to evaluate degradation and weathering resistance
These environmental tests in materials make it possible to analyze behavior against external agents such as solar radiation, UV radiation, temperature, humidity, or aggressive atmospheres, which can cause progressive material degradation processes that are difficult to detect in early stages. Phenomena such as discoloration, loss of mechanical properties, cracking, oxidation, or premature aging are studied, especially in materials exposed to outdoor or weathering conditions.
At INFINITIA, we perform solar radiation and UV testing in materials using climatic chambers and specific equipment that simulate real exposure conditions. These tests allow the assessment of UV radiation resistance, stability against thermal cycles, and the influence of humidity in polymers, coatings, adhesives, or composite materials, identifying degradation mechanisms associated with prolonged exposure.
This type of weathering resistance testing is key to validating materials in outdoor applications, comparing solutions, and optimizing formulations or surface treatments. At INFINITIA, we use these studies to anticipate failures, improve durability, and ensure that materials maintain their functional and aesthetic properties over time under real service conditions.
Sectors where quality control and testing allow validation of materials, processes, and final products
Quality control and testing play a key role across a wide range of industrial sectors, as any product based on materials, components, and processes is subject to variability and potential deviations that may affect its performance. However, technical requirements, service conditions, and regulatory demands vary significantly depending on the sector, making it essential to adapt testing and validation strategies to each specific context.
At INFINITIA, we approach material and product quality control by combining characterization techniques, experimental testing, and analysis applied to the real operating environment. Our objective is not only to verify compliance, but also to interpret the behavior of the material or component, validate its performance, and generate useful technical information for decision-making, ensuring product reliability and process stability in each industrial sector.
Automotive quality control: components subject to load, fatigue and variable service conditions
In the automotive sector, materials and components are subjected to cyclic loads, vibrations, thermal variations, and aggressive environments that can cause progressive degradation or critical failures that are difficult to detect in early stages. Series production and high safety requirements mean that small deviations in materials, processes, or assemblies can have a significant impact on reliability, warranty costs, and manufacturer reputation.
- Mechanical behavior evaluation: analysis of fatigue, wear, plastic deformation, or fracture in components subjected to repeated loads and dynamic conditions.
- Material and process analysis: detection of deviations in raw materials, heat treatments, coatings, or manufacturing parameters.
- Validation under service conditions: simulation of temperature, humidity, corrosion, or accelerated aging to assess the real performance of the component.
At INFINITIA, we analyze these scenarios to determine whether problems originate from the material, design, production process, or operating conditions. This approach allows material selection to be optimized, design robustness to be improved, and the probability of failure in real applications to be reduced through the implementation of testing methods.
Electronics quality control: validation of components subject to thermal, environmental and assembly conditions
In electronics, materials and assemblies are subjected to thermal, electrical, and environmental conditions that can cause multifactorial failures. Component miniaturization, combined with high reliability and stability requirements, means that small deviations in materials or processes can generate functional problems that are difficult to identify and must be evaluated in a quality control laboratory.
- Thermal stability evaluation: analysis of degradation due to thermal cycling, overheating, differential expansion, or inefficient heat dissipation.
- Assembly and joint analysis: detection of failures in solder joints, adhesives, encapsulants, or multimaterial interfaces.
- Validation under use conditions: influence of humidity, chemical agents, vibrations, or prolonged use on system behavior.
At INFINITIA, we evaluate these factors to determine whether the failure is associated with materials, assemblies, or service conditions, enabling product reliability improvement, manufacturing process optimization, and reduction of field incidents.
Defense quality control: materials and components subject to extreme conditions and demanding operational environments
In the defense sector, materials and systems are subjected to extreme operating conditions, such as high mechanical loads, severe thermal variations, exposure to aggressive environments, and critical use situations. In this context, any deviation in materials, processes, or design can compromise system functionality, safety, or reliability, with relevant operational consequences.
- Evaluation of behavior under extreme conditions: analysis of impact resistance, fatigue, vibration, thermal shock, or exposure to corrosive environments.
- Material and compatibility analysis: detection of degradation, incompatibilities, or loss of properties in metals, polymers, coatings, or multimaterial systems.
- Validation under operational conditions: simulation of real use environments, including specific environmental, mechanical, and chemical conditions.
At INFINITIA, we analyze these scenarios to determine whether risks are associated with the material, design, manufacturing process, or operating conditions. This approach makes it possible to validate solutions, optimize materials, and ensure the reliability of systems under critical conditions, reducing uncertainty and improving decision-making in highly demanding technical environments.
Plastics and polymers quality control: materials subject to chemical, thermal and mechanical degradation
In polymeric materials, exposure to temperature, radiation, chemical agents, or mechanical stress can cause progressive degradation that affects their properties, highlighting the importance of an effective control plan. In addition, small variations in formulation, additives, or processing parameters can generate significant changes in material behavior.
- Material characterization: analysis of composition, molecular structure, filler distribution, and physical and chemical properties.
- Degradation evaluation: study of thermal aging, oxidation, hydrolysis, swelling, or loss of mechanical properties.
- Process analysis: influence of extrusion, injection molding, or curing parameters on the final behavior of the material.
At INFINITIA, we evaluate these factors to determine material suitability, optimize formulations, and prevent in-service problems, improving the durability and performance of the final product.
Metallurgy quality control: materials subject to structural loads, heat treatments and aggressive environments
In metallic materials, load, temperature, and environmental conditions can generate defects or degradation that compromise structural integrity, requiring rigorous quality control. Processes such as casting, machining, or heat treatments can introduce microstructural variations that affect material behavior.
- Mechanical testing: evaluation of tensile strength, fatigue, impact, creep, or deformation under different load conditions.
- Microstructural analysis: detection of cracks, inclusions, segregation, or internal defects using advanced techniques to assess material quality.
- Service condition evaluation: influence of corrosion, temperature, dynamic loads, or aggressive environments on failure.
At INFINITIA, we analyze these scenarios to identify the origin of defects and determine whether they are associated with the material, process, or operating conditions, enabling design optimization, process improvement, and failure risk reduction.
Construction quality control: materials exposed to environmental conditions and structural demands
In construction and infrastructure, materials are exposed for long periods to adverse environmental conditions, structural loads, and use cycles that can cause progressive degradation. These processes can evolve slowly but may compromise structural safety and service life.
- Environmental degradation analysis: study of corrosion, humidity, UV radiation, pollution, or thermal cycling in structural materials.
- Structural evaluation: detection of cracking, deformation, loss of adhesion, or degradation of protective coatings through testing and evaluation.
- Durability validation: analysis of long-term behavior and estimation of service life under real conditions.
At INFINITIA, we evaluate these scenarios to determine the origin of deterioration and define maintenance, repair, or replacement strategies, optimizing material service life and ensuring structural safety.
Quality control and testing laboratory at INFINITIA to minimize risks and improve decision-making
Quality control and testing is a key tool for transforming experimental data into well-founded technical decisions. At INFINITIA, we approach this service through an evidence-based methodology, where compliance is not only verified, but the real behavior of materials and products is interpreted. This reduces uncertainty in decision-making and ensures that actions are aligned with expected performance under use conditions.
By combining lifetime testing, degradation analysis, and material characterization, we help companies anticipate failures before they appear in production or in the market. This approach incorporates preventive analysis strategies that allow potential risks to be identified before they materialize, supporting proactive decision-making during design, validation, or industrialization phases. In this way, materials can be validated, alternatives compared, and designs optimized, generating applicable technical knowledge that improves product reliability and process robustness.
In addition, quality control has a direct impact on economic optimization. At INFINITIA, we work to reduce costs associated with maintenance, claims, rework, or product recalls by identifying deviations early and avoiding decisions based on assumptions. The integration of physicochemical analysis and industrial testing makes it possible to ensure production process consistency, improve operational efficiency, and achieve maximum quality.
In regulated sectors, this approach acquires an additional dimension by ensuring regulatory compliance and product safety. Working with INFINITIA means having a team capable of designing testing strategies adapted to each case, interpreting results, and proposing technical solutions, turning quality control into a strategic tool for continuous improvement and industrial risk reduction.

Frequently asked questions about quality control and industrial testing
When are quality control tests necessary for an industrial product?
Quality control tests are necessary whenever there is genuine uncertainty about the behaviour of a material or product: during development phases, when changing supplier or batch, after production incidents, or following market complaints. In these scenarios, relying solely on technical specifications or prior experience is not enough to guarantee the real-world performance of the product.
At Infinitia we have resolved cases where the product met all documentation requirements but failed in use — from unforeseen chemical incompatibilities between materials to premature degradation under environmental conditions not covered in the original validation. Working with an external technical partner allows these deviations to be detected before they become a problem, reducing technical risk and providing the experimental basis needed for sound decision-making. If you are unsure whether your case requires testing, contact us with no obligation.
What are the consequences of not carrying out testing-based quality control?
The absence of experimental validation typically leads to undetected defects that emerge in the advanced stages of a product’s lifecycle, when the cost of resolution is significantly higher. In-service failures, complaints, rework, or product withdrawals are common outcomes when technical decisions are made without experimental data.
Without the backing of an external technical partner, decisions about materials, processes, or suppliers are based on assumptions or documentary information that does not always reflect the actual behaviour of the supplied batch. We have seen this pattern in projects such as the evaluation of materials to reduce corrosion in chemical reactors, where the lack of prior characterisation had caused systematic in-service failures. The added cost of rework, warranties, and production stoppages is usually far greater than the cost of preventive analysis.
How are the most appropriate tests selected for a material or product?
Test selection depends on four key variables: type of material and its function within the product, actual conditions of use and service requirements, the nature of the technical problem to be solved, and the level of information currently available. There is no standard set of tests that applies to every case.
As a general guide:
- Composition and microstructure characterisation: necessary when the material is unknown or conformity against a specification needs to be validated.
- Mechanical testing (tensile, hardness, fatigue, impact): essential when the product is subject to load or dynamic stress.
- Environmental and ageing tests: indispensable for estimating durability under real conditions of temperature, humidity, or chemical exposure.
- Physicochemical analysis: required to identify composition, contaminants, impurities, or assess compatibility between materials.
At Infinitia we always begin with a technical diagnosis of the problem in order to define a testing strategy aligned with the real objective, avoiding unnecessary analysis and prioritising the techniques most representative of the specific case.
What is the difference between standardised tests and bespoke tests?
Standardised tests follow procedures established by bodies such as ISO, ASTM, UNE, or EN, enabling results to be compared under controlled conditions and facilitating conformity validation or benchmarking between materials. They are useful when a product must comply with a specific standard or when comparability with third-party results is required.
Bespoke tests are designed specifically to reproduce real conditions of use or critical scenarios not covered by any existing regulation. At Infinitia we frequently develop this type of study when a failure only reproduces under specific combinations of temperature, load, and chemical exposure, or when standard tests do not capture the variables that truly determine the product’s behaviour in service. You can see this approach applied in our comparative testing of technologies to eliminate industrial odours, where the real problem had no standard regulatory coverage.
What value does an external technical partner provide compared to a visual or documentary inspection?
An inspection can verify visible aspects or check technical documentation, but it does not explain the internal behaviour of the material or identify the root cause of problems. It is a useful control tool, but technically limited when the failure has microstructural, chemical, or mechanical causes that are not detectable to the naked eye.
Working with an external technical partner enables properties to be analysed, hypotheses to be validated, and the reasons behind failures to be understood. At Infinitia we combine techniques such as fractography and microscopy testing with physicochemical analysis and mechanical testing to turn quality control into a data-driven decision tool, not a matter of subjective interpretation. When the case requires it, results are formalised as an expert report with technical and legal validity.
Can failures that occur in real use be reproduced in controlled conditions?
Yes. Reproducing failures under controlled conditions is possible through tests designed to simulate real operating conditions: mechanical load, temperature, humidity, exposure to chemical agents, use cycles, or combinations of several simultaneous factors. This approach allows root-cause hypotheses to be validated experimentally before corrective decisions are taken.
At Infinitia we apply this methodology regularly within our forensic engineering services, reproducing the failure scenario under controlled conditions to confirm its origin and verify the actual effectiveness of the proposed solutions. A specific example is the analysis of gases released by thermal degradation of plastics, where controlled reproduction of the failure was key to identifying the actual degradation mechanism. This is especially relevant for recurring or intermittent failures, where acting without solid data typically leads to corrections that do not eliminate the root cause.
How do tests contribute to reducing industrial costs?
Tests allow deviations and risks to be identified in the early stages of development or production, preventing problems from escalating to series production or reaching the market, where the economic impact is exponentially greater. Detecting an incorrect material or a process deviation before transformation eliminates costs associated with scrap, rework, warranties, and line stoppages.
Furthermore, working with an external technical partner enables material selection to be optimised and purchasing decisions to be made on an experimental basis. At Infinitia we have applied this approach in projects such as the accelerated corrosion test to optimise laser marking on industrial materials, where experimental validation enabled process decisions to be made without the need for costly production trials. It is also the approach we apply in the approval of a new steel supplier to optimise costs, where experimental evidence replaces reliance on documentation alone.
How much does a quality control and industrial testing service cost?
The cost depends on three factors: the type and number of analytical techniques required, the volume and nature of the samples, and the scope of the study — ranging from a single test to a comprehensive study covering characterisation, durability, and root-cause analysis. A basic composition analysis is not comparable to an accelerated ageing study involving multiple techniques, combined environmental conditions, and the preparation of a technical report.
At Infinitia we always tailor the service to the actual technical objective: we prioritise the techniques most representative of the problem, avoid unnecessary tests, and optimise the cost-to-value ratio for the client. If you would like an estimate tailored to your case, contact us and we will send you a technical and commercial proposal.
How long does it take to obtain test results?
Standard turnaround times range from 1 to 4 weeks depending on the technical complexity of the study: basic composition or physical property characterisations fall at the lower end, while durability studies, accelerated ageing, or tests involving multiple variables are closer to the upper end.
For situations with an urgent impact on production, at Infinitia we offer an urgent quotation option that allows results to be obtained within 24–72 hours of sample receipt. In both cases, a precise definition of scope from the outset is key to optimising timelines without compromising the technical quality of the report. If your case cannot wait, indicate this in your contact request and we will handle it as a priority.
that need to be reproduced. Some analyses can be completed within a few days, while durability or aging studies require more time.
A proper definition of the scope from the outset allows timelines to be optimized and the most relevant tests in the testing laboratory to be prioritized, ensuring useful results in the shortest possible time.
Why does my supplier certify that the material meets specifications, yet the product fails in use?
Because technical specifications and conformity certificates do not guarantee the actual behaviour of the material under the specific conditions of use of the product. Factors such as the transformation process, interaction with other materials in the assembly, environmental service conditions, or variations within the admissible range of the specification can produce behaviour that differs significantly from what was expected.
At Infinitia we have resolved numerous cases of this type through comparative analysis between supplier samples and reference materials, combining comparative characterisation with behaviour testing under conditions of use. Working with an independent external technical partner makes it possible to detect real differences that are not visible in the documentation and to make decisions based on experimental evidence, not just documents.
Why does the problem keep appearing even after attempts have been made to correct it?
When a problem recurs after a correction has been applied, it is usually because the solution addressed the visible symptom rather than the root cause. Without experimental validation confirming the actual origin of the failure, it is common to implement measures that temporarily mitigate the problem without eliminating it.
At Infinitia we address this situation through a root cause failure diagnosis based on experimental evidence, systematically ruling out hypotheses until the actual failure mechanism is identified. Only from that point is it possible to apply genuinely effective solutions and validate — also through testing — that the correction resolves the problem under representative conditions.
How is the technical validity and traceability of test results ensured?
The technical validity of results depends on four factors: correct definition of the test protocol, representativeness of the samples relative to the actual problem, traceability of the equipment and methodologies used, and adequate interpretation of the data in its technical context. Data without context does not enable decision-making.
At Infinitia, tests are designed and carried out by specialist engineers with multisectoral experience, and results are formalised in detailed technical reports that allow informed action to be taken. When a case involves a technical dispute, a supplier claim, or legal proceedings, we have the capacity to produce failure mode studies with the methodological rigour required for use in legal or arbitration proceedings.
