The CSA Group has published 18 new standards to support the safe deployment of LNG vehicles. This includes the LNG 3 series, which contain 17 standards covering LNG vehicle fuel system components and LNG 4.1 for vehicle dispensing systems.

摘要

The CSA Group is an organization that develops standards in 57 areas, including the LNG and compressed natural gas (CNG) fields. The LNG 3 series are bi-national adoptions of the international ISO 12614 Road Vehicles—Liquefied Natural Gas (LNG) Fuel System Components: 2014 19-part series. Seventeen of the 19-part standards have been adopted, with deviations, in both the US and Canada. CSA LNG 3.1 covers general requirements and definitions; while CSA LNG 3.2 covers performance and general test methods. The LNG 3 series covers the various LNG vehicle components such as valves, fittings, gauges and sensors while LNG 4.1 is a bi-national standard for LNG dispensing systems. The standard applies to newly-manufactured stationary and mobile vehicle LNG dispensing systems.
