For many manufacturing companies, product longevity is important to their success and growth. Many products are exposed to environmental conditions at any time throughout their lives. Sunlight, heat, water, as well as other environmental conditions will degrade, change colour, crack, or weaken a product over time. Manufacturers use specialized testing and measuring equipment to assess how different materials react to these environmental conditions.
One of the best means of evaluating materials is with an environmental test chamber (ETC) that performs UV aging. ETC's simulate long-term exposure to ultraviolet radiation and other environmental conditions in a controlled laboratory environment. By using ETC's, manufacturers can evaluate product performance over time, enhance their material quality, and verify their products are compliant with governing agencies.
What is an Environmental Test Chamber for UV Aging?
A UV aging environmental testing chamber is designed to mimic the effects of exposure to sunlight and the natural elements that materials would be exposed to over a long period. The test chamber exposes test samples to UV light, heat, and humidity to accelerate the aging of those test samples.
This method of accelerated environmental testing will enable manufacturers to understand how their products will behave after long-term exposure to sunlight and the elements outdoors.
Some examples of materials that are typically exposed to aging in UV Test Chambers include:
-
Plastic and polymer materials
-
Rubber materials
-
Paint and coating materials
-
Automobile parts
-
Packaging materials
By replicating environmental conditions within the chamber, engineering teams are able to identify customers' materials degrading at a significantly quicker rate than if they waited until their material was to degrade through natural exposure to the elements.
Why UV Aging Testing is Important
One of the most prevalent factors affecting how long a product lasts is ultraviolet (UV) radiation. When a product is consistently exposed to sunlight, it can cause the material to weaken, lose its colour, and ultimately shorten its life.
UV ageing tests can help manufacturers in several ways. Specifically, they provide the following four benefits:
1. Identify weaknesses in the material
2. Improve the durability of the product
3. Create new materials that have UV resistant properties
4. Verify that a product will be reliable, once placed outside And, should products not be adequately tested,
They may fail to meet quality standards when placed in actual operating environments due to environmental conditions.
Role of Test and Measurement Equipment in Quality Control
Modern industries that manufacture products rely significantly upon test and measurement devices as tools to produce consistency in quality of product. Environmental test equipment gives engineers the opportunity to evaluate the performance of materials when subjected to controlled stress situations.
The following are some of the common advantages of performing testing:
1) Durability evaluation that is accurate
2) A controlled environment in which to simulate actual conditions
3) Accurate, repeatable, and reliable test results
4) Conformity to industry standards
The use of these advanced testing devices helps manufacturers to create high-quality products while decreasing the chance of failure for those products.
Applications of UV Aging Test Chambers
Chambers designed specifically for performing UV ageing tests are commonly found within various industry sectors that have to manufacture products intended for use in difficult environmental conditions.
Common examples of industries that use UV ageing test chambers include:
1. Automotive - testing of exterior plastic parts & coatings.
2. Packaging - evaluating how well packaging materials resist UV light.
3. Construction materials - testing of outdoor building products.
4. Electronics - testing of electrical and/or electronic component performance when exposed to UV light.
By conducting tests on products manufactured or produced by these industries to determine if they will perform as designed (i.e. stay strong and look good) when subjected to extended periods of exposure to the sun's rays.
Reliable Testing Solutions for Manufacturers
Manufacturers require reliable and advanced environmental testing systems in order to conduct accurate durability testing. Quality test and measurement equipment provides manufacturers with the ability to have precise control over the environmental conditions during their testing.Companies such as Testronix Instruments will provide advanced environmental test chambers that simulate real life environmental conditions, which allow for efficient run of UV aging tests and maintain product quality standards.
Conclusion
Manufacturers use environmental testing to determine the durability and reliability of their products. Products can be affected by environmental conditions, such as UV exposure, for years. An environmental test chamber with UV aging allows manufacturers to create an environment similar to that encountered over the course of a product's lifetime and simulate how the material will age.Manufacturers can use advanced testing equipment and measuring devices to find weaknesses in materials, improve product designs, and verify that they meet quality standards. By investing in reliable environmental testing solutions, manufacturers can create long-lasting products that will perform as expected even when used in the real world.
