[ Superseding IS 9000 (Part 6) : 1978 ].

New Standard from Last Update.

NATIONAL FOREWORD

This Indian Standard (Part 2/Sec 38) which is identical with IEC 60068-2-38 : 2021 ‘Environmental testing — Part 2-38: Tests — Test Z/AD: Composite temperature/humidity cyclic test’ was adopted by the Bureau of Indian Standards on recommendation of the Environmental Testing Procedures Sectional Committee and approval of the Electronics and Information Technology Division Council.

IS 9000 (Part 6) : 1978 ‘Basic environmental testing procedures for electronic and electrical items: Part 6 Composite temperature/humidity cyclic test’ was published in 1978 and was based on IEC Pub 68-2-38 : 1974. IEC Pub 68-2-38 : 1974 has been withdrawn and replaced by IEC 60068-2-38 : 2021. The superseding of these Standards has been undertaken to align it with the latest version of IEC 60068-2-38 : 2021.

The text of IEC Standard has been approved as suitable for publication as an Indian Standard without deviations. Certain terminologies and conventions are, however, not identical to those used in Indian Standards. Attention is particularly drawn to the following:

a) Wherever the words ‘International Standard’ appears referring to this standard, they should be read as ‘Indian Standard’.

b) Comma (,) has been used as a decimal marker, while in Indian Standards, the current practice is to use a point (.) as the decimal marker.
