The objective of this Standard is to provide the electrotechnology industry with a complete set of environmental test procedures published as a series under AS 60068 Environmental testing. This Standard is Part 3.6 of that series.

This part of IEC 60068 provides a uniform and reproducible method of confirming that temperature and humidity test chambers without load conform to the requirements, specified in climatic test procedures contained in IEC 60068-2 and is destined for users when conducting regular chamber performance monitoring.
