IEC 60981:2019 is available as IEC 60981:2019 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.
IEC 60981:2019 specifies requirements for extra heavy-duty electrical rigid steel (EHDERS) conduits, couplings, nipples and elbows for electrical installations, including communications and fibre optics. This document also specifies threads for these components. It is not applicable to the conduits specified in IEC 60423. This third edition cancels and replaces the second edition published in 2004. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the second edition:
- addition of provisions for alternative coatings to zinc;
- addition of elasticity test for organic coatings;
- new Annex B on tests for evaluating alternative exterior coatings applied on extra heavyduty electrical rigid steel (EHDERS) conduits.
