This part of IEC60721 is a technical report dealing with the correlation and transformation of the conditions given in IEC60721‑3‑7 to the environmental tests defined in IEC60068‑2.
An environment may consist of a number of environmental conditions such as dynamic, climatic and biological and other effects due to chemically and mechanically active substances. In this report, only dynamic and climatic conditions have been considered.
The purpose of this technical report is to provide the specification writer with guidance, together with a set of easy-to-use tables which correlate and transform these conditions.
