Environmental testing – Wikipedia

This calls for the relevant equipment specification, which is a governing document for production and supply of the equipment for the users and shall always invoke the tests and conditions laid down in this specification, to provide a common basis for comparison for performance of various electronic and electrical equipment under Service environments. Where called for, it is the first process in the test procedure. What is applicable for vibration test is not applicable for acceleration steady state test and vice versa To overcome this difficulty, the classification, wherever found necessary has been done individually for each uss or a group of tests.
