AZTEST® Enclosures

The automotive interior climate presents some unique challenges in the field of outdoor weathering. The automotive interior climate is different in the following ways:

1. Air temperatures are typically warmer than temperatures outside a car. With the windows rolled up in a hot sunny climate such as Phoenix, material temperatures can reach 102°C (215°F).
2. The light reaching interior parts is also different than outside a car. Automotive glass (typically either laminated or tempered), changes the spectrum of light, removing some ultraviolet wavelengths.

As a result of these differences, special interior tests have been developed to simulate the climate of an automotive interior. One such test is represented by General Motors GMW 3417 (GM 9538P) and Ford DVM 0020. Also, a new test method, ASTM G201, has been developed for general testing in glass-covered enclosures with air circulation. Please click on one of the links below for more information.
