At this time, UL is seeking Canadian participation on the Standards Technical Panel so we can move forward to adopt
•    UL 213, Standard for Rubber Gasketed Fittings for Fire-Protection Service, and 
•    UL 213C, Standard for Grooved and Plain End Fittings,
as NSCs fully harmonized for both Canada and the US with the following scopes:

UL 213

1.1 This standard covers rubber gasketed fittings intended for assembling sections of pipe in fire protection systems, for example, couplings to attach pipe sections end to end, and side outlets to attach pipe sections at right angles.

1.2 The products covered by this standard are intended for use in fire protection service as outlined by the following Standards of the National Fire Protection Association:

a)     Installation of Sprinkler Systems, ANSI/NFPA 13;

b)     Installation of Standpipe, Private Hydrant, and Hose Systems, ANSI/NFPA 14;

c)     Water Spray Fixed Systems for Fire Protection, ANSI/NFPA 15; and

d)     Installation of Private Fire Service Mains and Their Appurtenances, ANSI/NFPA 24.

1.3 The joints formed with the use of fittings covered by this standard prevent separation under pressure.

UL 213C

1.1 These requirements cover the construction and performance of Grooved and Plain End fittings intended to be joined to pipe or another fitting by couplings complying with the requirements of the Standard for Rubber Gasketed Fittings for Fire-Protection Service, UL 213.

1.2 For the purpose of this standard, Grooved and Plain End fittings include constructions having one piece cast devices and fittings fabricated from steel pipe that could be segmented and welded to form the fitting.
