1.1 SCOPE 1.1.1 This standard applies to newly produced gas appliance connectors, constructed entirely of new unused parts and materials, having nominal internal diameters of ¼, 3/8, ½, 5/8, and 1 inch, 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 feet. Connectors listed under this standard are intended for use with residential and commercial 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. 1.1.2 Appliance connectors complying with this standard are considered suitable for use with natural, manufactured, mixed and liquefied petroleum gases and LP gas-air mixtures. 1.1.3 Appliance connectors complying with this standard are for use with piping systems having fuel gas pressures not in excess of ½ pound per square inch (3.5 kPa). 1.1.4 If a value for measurement as given in this standard is followed by an equivalent value in other units, the first stated value is to be regarded as the specification. 1.1.5 All references to psi throughout this standard are to be considered gauge pressure unless otherwise specified. 1.1.6 Exhibit A contains provisions that are unique to Canada. 1.1.7 Exhibit B contains a list of standards specifically referenced in this standard, and sources from which these reference standards may be obtained.
