What was the challenge or problem to be solved?
In industrial environments, the validation of insulating materials is key to ensuring the correct functioning of electrical and electronic systems. Exposure to moisture can alter their properties and reduce their service life, especially when multiple suppliers are involved and differences between materials are not immediately apparent.
Given this situation, the need arose to establish a supplier approval process based on objective data. To this end, the development of a moisture test and custom testing was proposed to evaluate real behaviour under humidity conditions and compare materials under representative conditions, enabling more reliable decision-making.
Evaluation of insulating materials against moisture under real conditions
The client faced the challenge of evaluating different insulating materials whose behaviour under moisture was not clearly defined. Although all materials met basic specifications, there was uncertainty about their performance in demanding environmental conditions. This lack of information limited the ability to select the best option.
Evaluating insulating materials against moisture requires reproducing conditions that simulate the real environment of use. However, standard tests are usually based on generic conditions that do not always reflect the specific behaviour of the material in application. This creates a gap between laboratory results and field performance.
Exposure to moisture can modify the electrical and mechanical properties of insulating materials, directly affecting their functionality.
Furthermore, variability between suppliers introduced an additional layer of complexity. Apparently equivalent materials could exhibit different behaviours under prolonged humidity conditions. This situation made a comparative approach necessary to identify relevant differences.
In this context, the initial objective was to generate technical information that would allow the behaviour of each material to be evaluated objectively. It was not just about measuring, but about interpreting results in terms of their impact on the final application.
Supplier approval criteria based on material validation
The project’s objective focused on establishing clear technical criteria for supplier approval, based on experimental results obtained under representative conditions. Defining these criteria was key to ensuring the quality and reliability of the final product.
Material validation in this context meant going beyond compliance with basic specifications. It was necessary to evaluate the material’s behaviour under conditions that could affect its real performance, thereby reducing risks associated with premature failure or degradation.
From an operational perspective, having objective criteria facilitated decision-making and reduced dependence on subjective assessments. This contributed to improving the efficiency of the supplier selection process and to establishing more robust internal standards.
In this context, the development of a moisture test for insulating materials adapted to the specific case was proposed as the basis for defining these criteria, making it possible to align test results with the client’s actual needs and integrate them into their quality management system.
Technical challenge in custom testing for moisture behaviour
The main technical challenge of the project lay in designing a test that would reliably evaluate the moisture behaviour of insulating materials under specific conditions. Unlike standardised tests, this case required precise adaptation to the conditions of use.
Developing custom tests involves defining variables such as temperature, relative humidity, exposure time and loading conditions, so as to reproduce the real environment. This definition is critical to ensuring the validity of the results. An inadequate design can lead to incorrect conclusions.
A poorly defined test can generate unrepresentative results, compromising the validity of material approval.
Additionally, it was necessary to ensure the repeatability and comparability of results across different samples. This required rigorous control of experimental conditions. The consistency of the test was as important as its discriminating capacity.
From INFINITIA’s perspective, this challenge was approached as a material characterisation problem oriented towards decision-making. The key was to design a test sensitive enough to detect differences, yet robust against external variations. This balance between precision, representativeness and experimental control marked the starting point of the project.
How was it addressed or what was the solution?
The solution was developed from an approach focused on generating useful information for decision-making. Rather than applying a standard test, the decision was made to design a procedure adapted to the client’s context. This approach made it possible to focus the analysis on the variables that were truly relevant to the application.
The project was approached as a custom testing exercise, where every technical decision was aimed at maximising the representativeness of the test. The solution had to be capable of reproducing real conditions and generating comparable results across materials. This approach avoided generic analyses with limited applicability.
Custom material testing for controlled environmental evaluation
The solution was based on the design of a specific test aimed at the environmental evaluation of insulating materials under controlled moisture conditions. This approach made it possible to simulate situations representative of the use environment.
The custom material tests were designed considering key variables such as prolonged exposure to moisture and its impact on material properties. These conditions allow degradation phenomena to be observed that do not always appear in standard tests.
The use of climatic chambers and environmental control systems made it possible to maintain stable conditions throughout the test. This is fundamental to ensuring the reliability of results. A stable experimental environment reduces variability.
The controlled simulation of environmental conditions makes it possible to anticipate the material’s behaviour in real service.
This approach allowed comparable data to be obtained across different samples. Homogeneity in test conditions is key for carrying out comparative analyses. Without this basis, the interpretation of results loses validity.
Execution of custom tests by a team specialised in material characterisation
The development of the test involved the participation of INFINITIA’s materials innovation team, specialised in material characterisation and experimental design. This team was responsible for defining, executing and validating the test.
Test execution included sample preparation, definition of exposure conditions and monitoring of material behaviour. Each of these stages is critical to ensuring the quality of the result. Process control was continuous throughout.
The approach adopted made it possible to integrate different analytical techniques within the test. This contributes to obtaining a more complete picture of material behaviour. The combination of methods increases interpretive capacity.
Furthermore, the team adjusted the test based on results obtained, ensuring its suitability to the project’s objective. This iteration is characteristic of custom testing, where design evolves in line with the information generated.
Benefits for supplier approval through comparative material analysis
The development of the test made it possible to establish an objective basis for supplier approval, based on the real behaviour of materials under moisture conditions. This result provides direct value to the selection process.
One of the main benefits was the ability to carry out a material comparison under controlled and representative conditions. This makes it possible to identify differences that are not visible in technical specifications, providing more relevant information for the application.
The approach adopted helped to reduce uncertainty in decision-making. The availability of experimental data facilitates the selection of the most suitable materials, contributing to improving the quality of the final product.
Furthermore, the test made it possible to detect potential risks associated with the use of certain materials, reinforcing the client’s preventive capacity. In the medium term, the solution developed contributes to establishing proprietary technical criteria and to more robust supplier management.
