    Abstract - (Show below) - (Hide below)

    Establishes classes of environmental parameters and their severities, covering the extreme (short-term) conditions to which a product may be subjected when being transported, installed, stored and used. Separate groups of classes are given for different product applications.The contents of the corrigendum of December 1985 have been included in this copy.This consolidated version consists of the first edition (1984) and its amendment 1 (1987). Therefore, no need to order amendment inaddition to this publication.
