Not all chambers are designed the same. In fact, a chamber that suits all your businesses needs may need to be custom built. This is why many companies go through a testing company, rather than have an in house chamber. Going through a company also brings in a second level of expertise and trained eyes, which assists in finding flaws in products.
Chambers are designed for a wide variety of conditions and tests. Such as salt spray test chamber, high and low temperature test chamber, constant temperature and humidity test chamber, ultraviolet aging test chamber, xenon lamp aging test chamber, ozone aging test chamber and ovens. Tests can also focus altitude, explosive atmosphere, fluid compatibility, fungus, ice/freezing, rapid and explosive decompression, salt fog, sand and dust, solar radiation exposure, temperature and humidity, wind, waterproofness and immersion.
While choosing a company to preform the tests, it is important they follow industry standards. Testing standards include, ASTM International, Underwriters Laboratories, NSF International and FM Global
Canadian Standards Association. These organizations exist to withhold the highest code of ethics in the testing industry and ensure data and material are not compromised.
