Scope and object

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.

Transfer during storage is not included in the classification.

Environmental conditions directly related to fire or explosion and conditions related to ionizing radiation are excluded. Any other unforeseen incidents are also excluded. The possibility of their occurrence should be taken into account in special cases. Offshore locations 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.

A limited number of classes of environmental conditions is given, covering a broad field of application. The user of this standard should select the lowest classification necessary for covering the conditions of intended storage.
