Abstract

This Standard applies to gas hose connectors (See Clause 3 Definitions), 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 for: <br>a) connection of portable outdoor gas-fired appliances to the gas supply piping; <br>b) use in unconcealed outdoor locations; <br>c) 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) use with natural gas , manufactured gas, mixed gases, propane and LP gas-air mixtures; and <br>e) use on gas piping systems having fuel gas pressures not in excess of 1/2 psi (3.45 kPa). <br>All references to psi throughout this Standard are to be considered gauge pressure unless otherwise specified. <br>Annex A contains provisions that are unique to Canada. <br>Clause 2 contains a list of standards specifically referenced in this Standard and sources from which these reference standards may be obtained. <br>This Standard contains SI (Metric) equivalents to the yard/pound quantities, the purpose being to allow the standard to be used in SI (Metric) units. (IEEE/ASTM-SI-10 is used as a guide in making metric conversion from yard/pound quantities.) If a value for a measurement and an equivalent value in other units, the first stated is to be regarded as the requirement. The given equivalent value may be approximate. If a value for a measurement and an equivalent value in other units, are both specified as a quoted marking requirement, the first stated unit, or both shall be provided. <br>In this Standard, "shall" is used to express a requirement, i.e., a provision that the user shall satisfy in order to comply with the standard; "should" is used to express a recommendation or that which isadvised but not required; and "may" is used to express an option or that which is permissible within the limits of the standard. <br>Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material. <br>Notes to tables and figures are considered part of the table or figure and may be written as requirements. <br>Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.
