Abstract

Defines safety requirements for the material, design, manufacture and testing of automatic valves used in gaseous hydrogen vehicle fueling stations.

Scope

This Standard contains safety requirements for the material, design, manufacture and testing of automatic valves (see Clause 3) used in gaseous hydrogen vehicle fueling stations. This Standard applies to newly manufactureda) Pneumatically actuated valvesb) Check valvesc) Excess Flow valvesd) Electrically actuated valves1.1This Standard does not apply to:a) Hydraulically actuated valvesb) Pressure regulating valvesc) Pressure relief valves; ord) Fueling nozzle valves as covered by the Standards for Compressed Hydrogen Surface Vehicle Refueling Connection Device, SAE J2600, or ISO 172681.1.1A valve that complies with the requirements for a Class A valve may be used for a Class B valve application, however, a Class B valve may not be substituted for a Class A valve. (see Clause 3).1.1.2All references to pressure throughout this document are to be considered gauge pressures unless otherwise specified.1.1.3All dimensions used in this standard are in metric units [International System of Units (SI)], unless otherwise specified. If a value for a measurement, as given in this standard, is followed by an equivalent value in other units, the first stated is to be regarded as the specification.1.2This Standard contains SI (Metric) corresponding to the yard/pound quantities, the purpose being to allow the standard to be used in SI (Metric) units. (Standard for use of the International System of Units (SI): The Modern Metric System, IEEE/ASTM SI I0 or ISO 80000-1:2009 Quantities and units- Part 1: General are used as a guide in making metric conversion from yard/pound quantities.) 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 shall be provided.
