This part of IEC 60068 describes a generic process for developing a climatic sequential test programme by sequencing test methods selected from the IEC 60068-2 series.

This generic process comprises a systematic approach to the development of a sequential environmental test programme.

A climatic sequential test is applicable to electrical, electromechanical or electronic equipment and devices, as well as their subassemblies, constituent parts and components. It can be customized according to specific product requirements and applications.

The process is designed for use by product designers, manufacturers and users.

The process is particularly relevant to electrical products which include components or materials that have the potential to degrade, as a consequence of environmental exposures.
