CSA ANSI Z21.24-2006/CSA 6.10-2006 (R2011)

This standard applies to newly produced gas appliance connectors, constructed entirely of new unused parts and materials, having nominal internal diameters of 1/4, 3/8, 1/2, 5/8, 3/4 and 1 in, and having fittings at both ends provided with taper pipe threads for connection to a gas appliance and to house piping. This standard covers assembled appliance connectors not exceeding a nominal length of 6 ft (1.83 m). Connectors listed under this standard are intended for use with gas appliances that are not frequently moved after installation.

For the purpose of this standard, an unused connector, including end fittings, is considered to be a connector which has not been installed.
