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. 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 C22.1-12@ Canadian Electrical Code (CE Code)@ Part I and NOM-001-SEDE@ Standard for Electrical Installations. 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.
