23、This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by December 2017, and conflicting national standards shall be withdrawn at the latest by December 2017. Attention is drawn to the possibility that some
24、 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 Commission and the European Free Trade Association. EN 16723 consists o
25、f the following parts, under the general title “Natural gas and biomethane for use in transport and biomethane for injection in the natural gas network”: Part 1: Specifications for biomethane for injection in the natural gas network Part 2: Automotive fuel specification According to the CEN-CENELEC

BS EN 16723-2:2017EN 16723-2:2017 (E) 4 Introduction This European Standard was prepared by CEN/TC 408 in re
28、sponse to the European Commission standardization mandate M/475. The mandate asks for the development of a set of quality specifications for biomethane to be used as a fuel for automotive vehicle engines and to be injected in natural gas pipelines (network). However, the scope of the standard was wi
29、dened according to BT decision C109/2012 that redefined the scope of CEN/TC 408: Standardization of specifications for natural gas and biomethane as automotive vehicle fuel and of biomethane for injection in the natural gas grid, including any necessary related methods of analysis and testing. Produ
30、ction process, source and the origin of the source are excluded. NOTE The CEN Technical Board (CEN/BT) is responsible for coordinating the work between technical bodies in order to achieve a coherent set of standards and to avoid overlaps. One of the aims of European policy in the field of energy is
31、 to increase the security of energy supply in the EU, as well as to contribute to reducing the emission of greenhouse gases accepted by the EU at Kyoto. In this context, special focus is given to the development and use of energy from renewable sources of biological and non-biological origin. Figure
32、 1 provides a visual representation of some applications of biomethane. Mandate M/475 indicates that the requirements for natural gas quality for injection in the natural gas network are developed by CEN/TC 234 in answer to Mandate M/400 on natural gas quality. CEN/TC 408 should consider the work of
33、 the pending mandate M/400 on gas quality, and should refer to the parameters as defined and specified in EN 16726. This standard should exclude the definition of any parameters or substances that are addressed in EN 16726. However, it may specify more strict limits for parameters or substances uniq
34、ue to biomethane if deemed technically necessary. If needed, additional parameters or substances should be defined.

36、) 6 1 Scope This European Standard specifies the requirements and test methods for natural gas (group L and H, as in EN 437), biomethane and blends of both at the point of use as automotive fuels. This European Standard applies to the previously mentioned fuels irrespective of the storage state (com
37、pressed or liquefied). To check compliance with some requirements set by the standard, LNG or liquefied biomethane should be re-gasified prior to testing. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its ap
38、plication. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.
