Preface The ultimate purpose for this document is that it constitute the performance standard for North America regarding fueling station reciprocating compressors applicable to dispensing natural gas to vehicles. Major funding in support of the consensus process for this Standard was provided by the Natural Gas Vehicle Coalition (NGVC), whose assistance is acknowledged with thanks. Scope This standard contains safety requirements for the material, design, manufacture and testing of gaseous hydrogen hose and hose assemblies which are used as a part of the dispensing station to connect the dispenser to the refueling nozzle; used as part of a vehicle on-board fuel system; or used as vent lines which carry gas to a safe location for either vehicles or dispensing systems.
