This Standard includes a series of methods of environmental test and their appropriate severities, and prescribes various atmospheric conditions for measurements and tests designed to assess the ability of specimens to perform under expected conditions of transportation, storage and all aspects of operational use. Although primarily intended for electrotechnical products this publication is not restricted to them and may be used in other fields.

IEC 60068 includes a series of methods of environmental test and their appropriate severities, and prescribes various atmospheric conditions for measurements and tests designed to assess the ability of specimens to perform under expected conditions of transportation, storage and all aspects of operational use. Although primarily intended for electrotechnical products this publication is not restricted to them and may be used in other fields where desired. Other methods of environmental test, specific to the individual types of specimen, may be included in the relevant specifications.
