1 Scope 1.1 This Standard applies to independently operating gas compressor packages designed for installation in accordance with (a) CAN/CSA-B149.1 when used for filling vehicles; or (b) CSA B108 when used for filling gas storage or piping systems. 1.2 This Standard applies to independently operating gas compressor packages that are (a) intended to be used for natural gas only; (b) intended for installation only in non-hazardous locations; and (c) designed so as not to create a hazard through leakage. 1.3 This Standard applies to gas compressor packages that are (a) certified as a system for the direct fuelling of vehicles. In this package the system includes components necessary to transfer fuel to a vehicle such as breakaway devices, delivery hoses, and fuel transfer nozzles. Nozzles, hose assemblies, and breakaway devices are not interchangeable between the P30 system and other pressure systems; or (b) certified for use with a piping system or to fill gas storage but not connected to a vehicle. In such cases, the certification need not include components such as the breakaway device, delivery hose, or fuel transfer nozzle. 1.4 This Standard applies to multiple-hose gas compressor packages and multiple accessories (as covered under the Scope) that form a part of the system. 1.5 This Standard applies to compressor packages intended for use on a system voltage of 600 V or less, designed to be used in accordance with the Canadian Electrical Code, Part I. 1.6 A compressor package is investigated under this Standard for reliable and safe operation at ambient temperatures of -40 degrees C (-40 degrees F) and the manufacturer's declared maximum ambient temperature rating; this declared rating is not less than 40 degrees C (104 degrees F). 1.7 This Standard is written in SI (metric) units.
