Abstract

<strong>Scope and references</strong> <br>This Standard details mechanical, physical, and electrical requirements for a newly manufactured appliance that dispenses natural gas for vehicles directly into the vehicle natural gas fuel storage system, referred to as a residential fueling appliance (RFA). <br>These requirements apply to appliances for: <br>a) natural gas only (see Clause 1.1); <br>b) outdoor or indoor installation in nonliving spaces (e.g., garage); <br>c) ambient temperature not below minus 40&#176;F (minus 40 &#176;C); <br>d) nominal voltage not exceeding 240 VAC; <br>e) fill pressure not exceeding specified vehicle service pressure; <br>f) maximum inlet flow rate not exceeding 10 SCFM (0.3 SCMH); <br>g) intended to be connected to residential utility gas piping system in accordance with requirements of the applicable Code; <br>h) intended to meet the installation fire safety requirements in accordance with the requirements of the applicable Code; and <br>i) single hose gas compressor packages. <br>All references to "psi" throughout this Standard are to be considered gauge pressures, unless otherwise specified. <br>In the case of conflict between this Standard and Federal, National, Provincial, State, or local requirements, the government requirements take precedence. <br>This Standard contains SI (Metric) units corresponding to the yard/pound quantities, the purpose being to allow the standard to be used in SI (Metric) units. If a value for a measurement and a corresponding value in other units are stated, the first stated value is to be regarded as the requirement. The given corresponding value may be approximate. If a value for a measurement and a corresponding value in other units are both specified as a quoted marking requirement, the first stated unit, or both are to be provided. <br>Note: <em>IEEE/ASTM SI 10 or ISO 80000-1 is used as a guide in making metric conversion from yard/pound quantities.</em> <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 is advised 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.
