PURPOSE

This test is intended to evaluate the effect of absorption and diffusion of moisture and moisture vapor on component parts. The test is an artificial environmental test and is severely accelerated to shorten testing time. This test is more severe than Method 1. This test is of value in determining the resistance of the component parts to the inroads of moisture, but should not be considered as a tropical test for all types of component parts. This test method provides a means of performing humidity testing without the need for specialized humidity test equipment.
