Abstract

This standard applies to gas hose connectors, hereinafter referred to as connectors. They are conduits for conveying gas and depend for gas-tightness on the wall structure of the hose material. Such connectors shall be: <br>a. Newly produced and constructed entirely of new, unused parts and materials; and <br>b. Equipped with a fitting at each end provided with standard taper pipe threads. <br>Connectors covered by this standard are intended: <br>a. For connection of portable outdoor gas-fired appliances to the gas supply piping; <br>b. For use in unconcealed outdoor locations; <br>c. For use only in locations where they will not be likely to be subject to excessive temperatures [above 200&#176;F (93.5&#176;C)]; <br>d. For use with natural, manufactured, mixed and liquefied petroleum gases and LP gas air mixtures; and <br>e. For use on gas piping systems having fuel gas pressures not in excess of &#189; psi (3.45 kPa). <br>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 requirement. <br>All references to psi throughout this standard are to be considered gage pressure unless otherwise specified. <br>Exhibit A contains provisions that are unique to Canada. <br>Exhibit B contains a list of standards specifically referenced in this standard and sources from which these reference standards may be obtained.
