UL 6A:2021 is a standard that covers the requirements for electrical rigid metal conduit (ERMC) made of aluminum (ERMC-A) and stainless steel (ERMC-SS). It includes conduit, nipples, elbows, and couplings in trade sizes ranging from 3/8 to 6. This standard is applicable for use as a metal raceway for the installation of wires and cables in accordance with various electrical codes such as the Canadian Electrical Code, National Electrical Code, and Standard for Electrical Installations.

It is important for the user to determine the appropriate product for their specific application. The standard also encompasses red brass (ERMC-RB) electrical rigid metal conduit, nipples, elbows, and couplings in trade size 16 (1/2), which are specifically designed for direct burial and swimming pool applications in compliance with national electrical installation codes.

Steel conduit is not covered in UL 6A:2021 and falls under other standards listed in the reference items of Annex A.
