INTERNATIONAL SPECIFICATIONS

EMT pipes are manufactured in accordance with the latest edition of the following :

American National Standard Institute – American National Standard for (ANSI C80.3)

ANSI C80.3 covers the requirements for steel EMT for use as a raceway for wires or cables of an electrical system. This revision includes added requirements for alternate corrosion resistant coating and updated normative references. This standard covers the requirements for steel electrical metallic tubing, for use as a raceway for wires or cables of an electrical system. Finished tubing is typically furnished in nominal 10 ft (3.05 m) lengths. It is protected on the exterior surface with a metallic zinc coating or alternate corrosion protection coating (see UL 797 Eighth edition Clauses 5.3.3, 6.2.4, 7.5 and 7.6) and on the interior surface with a zinc or organic coating. This standard also covers electrical metallic tubing elbows. Properly assembled systems of steel electrical metallic tubing and elbows, manufactured in accordance with this standard, and other identified fittings provide for the electrical continuity required of an equipment grounding conductor.

Under writers laboratories Standard for Electrical Metallic Tubing (UL 797)

These requirements cover electrical metallic tubing - steel (EMT) and elbows for use as a metal raceway for installation of wires and cables in accordance with CSA C22.1,  Canadian Electrical Code, Part 1, NOM-001-SEDE,  Standard for Electrical Installations, and NFPA 70,  National Electrical Code (see Reference Item No. 1, Annex a). EMT is provided with a zinc, zinc-based, nonmetallic, or other alternate corrosion-resistant exterior coating and an organic or zinc interior coating. It is the users' responsibility to determine the appropriate product for their application.

RMC pipes are manufactured in accordance with the latest edition of the following:

American National Standards for Electrical Rigid Conduit (ANSI C80.1)

ANSI C80.1 Establishes the requirements for electrical rigid steel conduit for use as a raceway for wires or cables of an electrical system. Raceway systems (conduit, fittings, and enclosures) are relied upon to provide mechanical protection for circuit conductors and to carry potentially dangerous fault currents.

This standard covers the requirements for electrical rigid steel conduit for use as a raceway for wires or cables of an electrical system. Finished conduit is produced in nominal 10 ft (3.05 m) lengths, threaded on each end with one coupling attached. It is protected on the exterior surface with a metallic zinc coating or alternate corrosion protection coating (as specified in clauses 5.3.3, 6.2.4, 7.8, and 7.9 in UL 6) and on the interior surface with a zinc or organic coating. This standard also covers conduit couplings, elbows, nipples, and conduit lengths other than 10 ft (3.05 m). Properly assembled systems of conduit, couplings, elbows, and nipples, manufactured in accordance with this standard, and other identified fittings provide for the electrical continuity required of an equipment grounding conductor.

Under writers laboratories Standard for Electrical Rigid Conduit (UL 6)

These requirements cover electrical rigid metal conduit - steel (ERMC-S), elbows, couplings, and nipples for use as a metal raceway for installation of wires and cables in accordance with CSA C22.1,  Canadian Electrical Code, Part 1, NOM-001-SEDE,  Standard for Electrical Installations, and NFPA 70,  National Electrical Code (see Reference Item No. 1, Annex a). ERMC-S is provided with a zinc, zinc-based, nonmetallic, or other alternate corrosion-resistant exterior coating and an organic or zinc interior coating. It is the user's responsibility to determine the appropriate product for their application.
