Scope

This part of IEC 60721 deals with the correlation and transformation of the conditions given in IEC 60721 -3- 4 to the environmental test procedures defined in IEC 60068 -2.

This document provides test procedures and test severities for electrotechnical equipment operated at stationary non-weather protected locations for the product classes set out in IEC 60721 3 4.

An environment can consist of several environmental conditions such as dynamic, climatic, and biological, and other effects due to chemically and mechanically active substances. In this document, dynamic, air pressure, biological and climatic conditions have been considered.

The purpose of this technical specification is to provide the specification writer with guidance together with a set of easy-to-use tables which correlate and transform these environmental conditions.

Purpose

According to Decision 104_09/2023

The recommendations in the minutes of MT 19 were approved by the Plenary.
