This standard method sets out a test procedure, the object of which is to provide a composite test, primarily intended for components, to determine in an accelerated manner the resistance of specimens to the destructive effects of high temperature/humidity and cold conditions.

This standard method sets out a test procedure, the object of which is to provide a composite test, primarily intended for components, to determine in an accelerated manner the resistance of specimens to the destructive effects of high temperature/humidity and cold conditions. The test employs temperature cycling at highrelative humidity and will produce a 'breathing' action of moisture into partially sealed containers.The test includes exposure to low temperatures to determine the effects of periodic icing.
