IEC TS 60721-4-3:2023 This part of IEC 60721 deals with the correlation and transformation of the conditions given in IEC 60721-3-3 to the environmental test procedures defined in IEC 60068-2.
This document provides test procedures and test severities for electrotechnical equipment operated at stationary weatherprotected locations for the product classes set out in IEC 60721-3-3.
This first edition cancels and replaces IEC TR 60721-4-3:2001 and IEC TR 60721-4-3:2001/AMD1:2003. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to IEC TR 60721-4-3:2001 and IEC TR 60721-4-3:2001/AMD1:2003:
a) the document has been totally reworked;
b) all figures have been removed, except in Annex A;
c) severities have been aligned with those of IEC 60721-3-3:2019.
