From the requirements documents, determine the function to be performed by the equiPment and the deployment or deployment location which could result in exposure to sudden changes in ambient temperature. ,. b. ~. The primary objectives of the temperature shock are to determine if:
test (1) The test item can satisfy its performance requirements after exposure to.eudden changes in temperature of the surroundingatmosphere. (2) The test item can be aafely operated following’exPosure to’the sudden ohanges in temperature of the surrounding atmosphere. 0. ~. Several exposure situation are addreesed within this method: aircraft flight expoeure, air delivery - desert, end ground transfer or air delivery - arctic. Based on the anticipated deployment; determine which teet variation is applicable. The meet extreme expoeure range should determine the test oonditiona, but test levels may be extended to detect deeign flaws. (~) ~ .
