Revised were cold, dry heat, and damp heat, cyclic(12h+12h cycle) tests of IEC Pub. 60068 climatic environmental test standards in 2007, but as of today the revision of the corresponding KS has not been followed yet. The revised test standards are compared with the prerevision ones in terms of the types of tests and test severities. This study shows the difference between the prerevision and the postrevision standards, which will provide the latest information to the industries and be helpful in revising the KS.
