Describes the tests on capacitors to establish, under laboratory conditions, their suitability for use over stated ranges of temperature, air pressure and humidity, their ability to withstand specified conditions of mechanical shock such as are to be expected under transit or operational conditions, their ability to withstand the rigours of normal assembly processes attendant on their incorporation in equipment. See IEC 612.
