Abstract

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.

RECONFIRMATION NOTICE
Major stakeholders of this publication have reviewed the content of this publication and in accordance with Standards Australia procedures for reconfirmation, it has been determined that the publication is still valid and does not require change.

Scope

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.
