13、by October 2018.Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN shall not be held responsible for identifying any or all such patent rights.This document has been prepared under a mandate given to CEN by the European Commissio

14、n and the European Free Trade Association.This document has been prepared under the standardization request M/533 given to CEN by the European Commission and the European Free Trade Association in the framework of Directive 2014/94/EU on the deployment of alternative fuels infrastructure.The standar

15、dization request M/533 focuses on interoperability aspects of the alternative fuels infrastructure, which for CNG fuelling stations are covered in this document by the following items: Fuelling pressure (service pressure): This document applies a fuelling pressure of 20,0 MPa gauge (200 bar) at 15 C

16、. This document allows possible higher fuelling pressures if the necessary requirements as provided are met accordingly. When adopting the fuelling pressure of 20,0 MPa at 15 C, the maximum fuelling pressure can be 26,0 MPa with “temperature compensation”. Connector profile: The harmonized connector

17、 profile is described in EN ISO 14469:2017, that specifies CNG refuelling nozzles and receptacles constructed entirely of new and unused parts and materials, for road vehicles powered by CNG, and which is referenced in this document as well as included in UN/ECE Regulation N 110. EN ISO 14469:2017 r

18、efers to fuelling pressures of 20 MPa and 25 MPa for both “size 1“ (B200 and B250) and “size 2“ (C200 and C250).In addition to interoperability aspects, the following aspects are relevant for applying this document in Europe: Fuel quality: The quality of CNG for use as automotive fuel is covered in

19、EN 16723-2:2017, that specifies the requirements and test methods for natural gas, biomethane and blends of both. Fuel labelling: The fuel label for CNG at dispensers is covered by EN 16942:2016, that lays down harmonized identifiers for marketed liquid and gaseous fuels, and which has also been dev

20、eloped to support Directive 2014/94/EU.According to the 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 Yugo

30、tandardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the ri

31、ght to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedure

32、s used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial r

33、ules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights.
