Scope:

This Standard contains requirements for non-threaded, quick-connect couplings of the internal lug design for use in fire protection service. (See Appendix A.)

The couplings are intended for use with fire hose in the following standard sizes: 38 mm, 65 mm, 100 mm, 125 mm and 150 mm.

This Standard also contains requirements for the non-threaded, quick-connect portion of adaptor fittings intended for use in modifying threaded fittings to accommodate couplings of the internal lug design. The remaining requirements for these adaptor fittings shall be in accordance with the applicable sections of the Standard for Threaded Couplings for 1-1/2- and 2-1/2-Inch Fire Hose, ULC-S513.

NOTE: It is also intended that this Standard will contain, in a future edition, requirements for adaptors intended for use in modifying couplings of the external lug design to accommodate the attachment of couplings of the internal lug design.

Project need:

Currently, CAN/ULC S543, Standard for Internal Lug Quick-Connect Couplings for Fire Hose, includes dimensions of gauges for 4” (100 mm) couplings but there are no dimensions for the actual couplings. The standard also includes dimensions for 5” (125 mm) couplings and gauges. NFPA 1963, Standard for Fire Hose Connections, only includes gauge dimensions and per industry needs, only including the dimensions of the gauges is suitable. It is being proposed that the reference to 5” (125 mm) couplings and gauges be removed to ensure that this ULC Standard is in alignment with other industry standards such as, NFPA 1963.
