DUS 2483: 2022, Standard Specification for Compressed Natural Gas (CNG) and Liquefied Natural Gas (LNG) Used as a Motor Vehicle Fuel, First Edition; (12 page(s), in English)
1.1 This specification defines the minimum fuel quality requirements for gaseous fuels consisting primarily of methane when used as an internal combustion engine fuel.
1.2 This specification defines the criteria for compressed natural gas (CNG), liquefied natural gas (LNG), or biogas when used as a fuel for internal combustion engines in motor vehicles.
1.3 This specification covers the needs of internal combustion engines designed for use in motor vehicles.
1.4 Fuels that have been enriched with hydrogen are outside the scope of this specification.
1.5 This specification applies to the fuel as delivered into the on-board fuel tanks of a motor vehicle either as a compressed gas or cryogenic liquified gas.
1.6 This specification may serve as a guide to gaseous fuel quality requirements for internal combustion engines used in stationary applications.
1.7 This specification is not a natural gas pipeline standard; those requirements are determined by national and regional tariffs. 1.8 Units—The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard.
