24、EN by the European Commission and the European Free Trade Association. For a list of significant technical changes between this European Standard and EN 1918-4:1998, see Annex B.

26、unctional recommendations for surface facilities. Directive 2009/73/EC concerning common rules for the internal market in natural gas and the related Regulation (EC) No 715/2009 on conditions for access to the natural gas transmission networks also aim at technical safety including technical reliabi

EN 1918-4:2016 (E) DIN EN 1918-4:2016-11 4 1 Scope This European Standard covers the functional recommendations for design, construction, t
30、esting, commissioning, operation, maintenance and abandonment of underground gas storage (UGS) facilities in mined rock caverns up to and including the wellhead. This European Standard does not cover the technology of lined rock. NOTE 1 Even if not covered in this standard, the lined rock is an avai
31、lable technology. This European Standard specifies practices which are safe and environmentally acceptable. For necessary surface facilities for underground gas storage, EN 1918-5 applies. In this context, “gas“ is any hydrocarbon fuel: which is in a gaseous state at a temperature of 15 C and under
32、a pressure of 0,1 MPa (this includes natural gas, compressed natural gas (CNG) and liquefied petroleum gas (LPG). The stored product is also named fluid); which meets specific quality requirements in order to maintain underground storage integrity, performance, environmental compatibility and fulfil
33、s contractual requirements. This European Standard specifies common basic principles for underground gas storage facilities. Users of this European Standard should be aware that more detailed standards and/or codes of practice exist. A non-exhaustive list of relevant standards can be found in Annex
34、A. This European Standard is intended to be applied in association with these national standards and/or codes of practice and does not replace them. In the event of conflicts in terms of more restrictive requirements in the national legislation/regulation with the requirements of this European Stand
35、ard, the national legislation/regulation takes precedence as illustrated in CEN/TR 13737 (all parts). NOTE 2 CEN/TR 13737 (all parts) contains: clarification of relevant legislation/regulations applicable in a country; if appropriate, more restrictive national requirements; national contact point fo
36、r the latest information. This European Standard is not intended to be applied retrospectively to existing facilities. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
