Classification of environmental conditions Part 3: Classification of groups of environmental parameters and their severities Introduction

Abstract

This Standard establishes classes of environmental parameters and their severities, covering the extreme (short-term) conditions which may be met by a product when being transported, installed, stored and used. Separate groups of classes are given for different product applications (e.g. weather-protected stationary, mounted in ground vehicles, transportation). The classes also take into account the degree of restriction of the use of the product from very restricted conditions (e.g. in temperature-controlled rooms) to unrestricted conditions. The classification covers natural as well as man-made conditions.
