IEC 61386-21 Revised

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).
