Scope:

1.1
This Standard applies to nonmetallic or composite mechanical protection tubing (MPT), and nonmetallic, composite or metallic fittings, and clamps used for the support, routing and mechanical protection of conductors, wires, and cables. The MPT, fittings, and clamps are intended to be used to interconnect separate component assemblies or consoles of electrical devices, such as robotics, medical or X-ray equipment. The mechanical protection afforded the internal wiring contained within the tubing is considered equivalent to the protection provided by a type SJT flexible cord. Mechanical protection tubing (MPT) may be submitted without fittings, clamps, etc.

1.2
The MPT, fittings, and clamps covered by this Standard are not intended for use as a wiring method in accordance with NFPA 70, National Electrical Code (NEC), CSA C22.1, Canadian Electrical Code (CE Code), Part I and NOM-001-SEDE Standard for Electrical Installations.

1.3
This Standard does not include standard trade sizes. The MPT, fittings, and clamps from different manufacturers are not interchangeable unless the combination of MPT, fittings, and clamps are determined to be in accordance with this Standard.

Project need:

This is a New Edition of the tri-national standard CSA C22.2 No. 227.3 / UL 1696 / NMX-J-855-ANCE to maintain alignment with international requirements and to update the current standard due to user experience/feedback/new technology. This proposed New Edition is being developed at the request of the industry and the CANENA Technical Harmonization Subcommittee on Nonmetallic Raceway Products and Accessories. It will provide the industry with guidance on acceptable construction and use of mechanical protection tubing (MPT) and fittings.
