Understanding how materials behave, deteriorate, and interact with each other is a fundamental part of manufacturing processes. Product and material comparison testing involves evaluating the suitability of materials for specific applications against design criteria, expected operating conditions, and applicable codes, standards, and customer requirements.
Today, advanced laboratories have a wide range of facilities and systems to specifically assess the properties and structural integrity of materials and products according to both national and international standards and customer requirements. These laboratories provide both non-destructive and destructive testing services for metals, composites, polymers, resins and elastomers to determine product and material properties, performance, strength, durability and resistance to factors such as corrosion and fatigue. High-quality material inspection services help businesses ensure that materials are compliant, safe and fit for purpose.
Product and materials testing services include aggressive environment testing, corrosion testing, mechanical testing, fatigue testing, hydrogen testing, residual stress measurement and welded polymer testing. Materials testing laboratories include fracture, fatigue, corrosion, environmental testing and combinations of these testing methods. This is supported by a range of materials analysis and characterization equipment, as well as non-destructive testing and condition monitoring capabilities. These services reach businesses across a wide range of industries, including those operating in the aerospace, transportation, power, energy, construction, medical and marine applications sectors.
Product and material comparison testing includes, but is not limited to, the following types of services:
Durability testing and the resulting life estimates for materials and products are often a challenge for any product development team. When designing a test program, the first concern is what the ideal test method for the material and product will be. The key is whether you want to test materials, components, or complete products. Testing samples of candidate materials for use in finished products can jump-start product development by verifying how the selected materials will behave when exposed to light, heat, and moisture.
A comprehensive material selection process takes time. Material-level testing helps identify the right material in a much shorter time compared to natural weathering and has the advantage of having both open-air and laboratory accelerated testing methods.
For example, conducting corrosion tests using xenon instruments helps answer these questions by exposing samples to high-fidelity simulations of natural sunlight, sunlight filtered through window glass, and retail lighting, in addition to defined relative humidity and room temperature conditions. The advantages of using this testing method include:
These four benefits enable realistic materials testing and qualification. With this testing, it is possible to focus on the physical change or degradation of materials due to UV photo-induced oxidations and secondary chemical reactions.
While component or product level testing is now being done, product durability tests are now being conducted under realistic environmental stress. These tests uncover all potential negative interactions between different materials used in the component or product. It is investigated whether the materials will work together and harm product performance or functionality. Such tests require larger environmental test chambers and use solar simulators.
Among the numerous tests, measurements, analyses and evaluation studies carried out for businesses in various sectors, our organization also provides product/material comparison testing services with its trained and expert staff and advanced technological equipment.
