IEC 61386-25:2011 specifies requirements and tests for conduit fixing devices used for support and/or retention of conduit for cable management.
This publication is to be read in conjunction with IEC 61386-1:2008.

This part of IEC 61386 specifies requirements and tests for conduit systems, including conduits and conduit fittings, for the protection and management of insulated conductors and/or cables in electrical installations or in communication systems up to 1 000 V a.c. and/or 1 500 V d.c. This second edition cancels and replaces the first edition published in 1996, and its Amendment 1 (2000), and it constitutes a technical revision. The changes to the first edition are as follows:
- change to the length of the test specimen between fittings for the tensile test,
- editorial and normative reference updates.

This International Standard specifies outside diameters for conduits used in electrical installations or in communication systems and the dimensional requirements for threads. It also specifies the dimensional requirements for threads used in associated fittings. It is not applicable to extra heavy-duty electrical rigid steel conduits specified in IEC 60981. This third edition cancels and replaces the second edition published in 1993. This edition constitutes a technical revision. The following main changes have been made to the second edition: -revised figures and tables plus editorial and normative reference updates -conduit range increased to 110 mm outside diameter.

IEC 61386-21:2002 specifies the requirements for rigid conduit systems. This part 21, which specifies particular requirements for rigid conduit systems, is to be used in conjunction with IEC 61386-1, Conduit systems for electrical installations – Part 1: General requirements, and its amendments. It was established on the basis of the first edition (1996) of that standard and its amendment 1 (2000).

IEC 61386-23:2002 specifies the requirements for flexible conduit systems. This part 23, which specifies particular requirements for flexible conduit systems, is to be used in conjunction with IEC 61386-1, Conduit systems for cable installations – Part 1: General Requirements 1, and its amendments. It was established on the basis of the first edition (1996) of that standard and its amendment 1 (2000).
