scope:

This section of IEC 60721-3 classifies the groups of environmental parameters and their severities to which products together with their packaging if any, are subjected when stored. The environmental conditions specified in this standard are limited to those which may directly affect the products or their ultimate performance. Only environmental conditions as such are considered. No special description of the effects of these conditions on the products is given. Environmental conditions directly related to fire or explosions are not included. Conditions of stationary use, portable and non-stationary use, use in vehicles and ships, and conditions of transportation are given in other sections of IEC 60721-3. The object of this standard is to classify environmental parameters and their severities to which a product may be exposed during storage. Transfer and handling during storage and transport are addressed in IEC 60721-3-2.
