Cable management systems - Specifications for extra-heavy-duty electrical steel conduit fittings and accessories

IEC 61950:2019(E) specifies requirements for conduit fittings, including conduit bodies used with extra-heavy-duty electrical rigid steel (EHDERS) conduit conforming to IEC 60981.
This document does not include requirements for fittings intended for installation in potentially explosive atmospheres.
This third edition cancels and replaces the second edition published in 2007. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
– change in title and scope to cover only fittings and accessories for use with extra­heavy­duty electrical rigid steel (EHDERS) conduits;
– new and updated definitions of terms;
– addition of requirements for expansion, expansion-deflection and deflection fittings;
– deletion of requirements for cast metal boxes.
A bilingual version of this publication may be issued at a later date.
