Environmental tests are used to verify an equipment that can withstand the rigors of harsh environments. In general, military products have lots of experiences with extreme environment compared to commercial products. Therefore, the military products used in mountains require a tailoring process about temperature drop for the environmental test. The International Organization for Standardization publishes that the coefficient of temperature drop is -6.5℃/1000m from all around the world. However, there is no the criteria in the South Korea. In this paper, we calculate the coefficient of temperature drop. Also, an equation used as a tailoring process for a low temperature test of the products has been suggested.
