Scope:

1.1
These requirements cover liquid-tight flexible nonmetallic conduit in the 3/8 – 4 (12 – 103) trade sizes of Type LFNC-A (Layered), Type LFNC-B (Integral), and Type LFNC-C (Corrugated) constructions. The conduit is intended for installation in accordance with the National Electrical Code (NEC), the CE Code, Part 1, and the Mexican Electrical Code, NOM-001-SEDE. The values in parentheses are metric trade designators of conduit.

1.2
Conduit covered by this Standard is intended for use in wet, dry, or oily locations at a maximum of 60°C (140°F), unless otherwise marked. (See Section 6.)

1.3
Fittings for liquid-tight flexible nonmetallic conduit are covered in UL 514B, CSA C22.2 No. 18.3, or NMX-J-017-ANCE.

Project need:

This is a new Amendment of the tri-national standard CSA C22.2 No. 227.2.1 / UL 1660 / NMX-J-764-ANCE to maintain alignment with international requirements and to update the current standard due to user experience/feedback/new technology. This proposed Amendment 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 liquid-tight flexible nonmetallic conduits.
