15、nfrastructure.The standardization request M/533 focuses on interoperability aspects of the alternative fuels infrastructure, which for LNG fuelling stations are covered in this document by the following items: Fuelling pressure (service pressure): This document requires that the pressure of LNG at t

16、he nozzle is lower than the maximum allowable working pressure of the vehicle tank. Connector profile: The harmonized connector profile is described in EN ISO 12617:2017, that specifies LNG refuelling nozzles and receptacles constructed entirely of new and unused parts and materials for road vehicle

17、s powered by LNG, and which is referenced in this document.In addition to interoperability aspects, the following aspects are relevant for applying this document in Europe: Fuel quality: The quality of LNG for use as automotive fuel is covered in EN 16723-2:2017, that specifies the requirements and

18、test methods for natural gas, biomethane and blends of both. Fuel labelling: The fuel label for LNG at dispensers is covered by EN 16942:2016, that lays down harmonized identifiers for marketed liquid and gaseous fuels, and which has also been developed to support Directive 2014/94/EU.According to t

19、he CEN-CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece,
