BS EN 12327:2012EN 12327:2012 (E) 4 Introduction There is a complete suite of functional standards prepared by CEN/TC 234, “Gas infrastructure“ to cover all parts of the gas infrastructure from the point of i
18、nput of gas to the transmission system up to the inlet connection of the gas appliances, whether for domestic, commercial or industrial purposes. In addition, a new EN Work Item is being prepared by CEN/TC 234/WG 10, “Gas Service Lines“. In preparing this European Standard a basic understanding of g
19、as supply by the user has been assumed. Gas infrastructures are complex and the importance on safety of their construction and use has led to the development of very detailed codes of practice and operating manuals in the member countries. These detailed statements embrace recognized standards of ga
20、s engineering and the specific requirements imposed by the legal structures of the member countries. BS EN 12327:2012EN 12327:2012 (E) 5 1 Scope This European Standard describes common principles for pressure testing, commissioning and decommissioning of gas infrastructures as covered by the functio
21、nal European Standards of the Technical Committee CEN/TC 234, see Annex B. They have been extracted from the detailed codes of practice and operating manuals in the member countries. This European Standard does not cover installation pipework which is covered by EN 1775. The specified procedures are
22、 applicable to strength testing, tightness testing and combined testing. Test pressure levels, test periods and acceptance criteria are not covered by this European Standard. Additional measures or different methods of testing, commissioning or decommissioning can be required by legislation of the i
23、ndividual member countries or at the discretion of the pipeline operator. This European Standard specifies common basic principles for gas infrastructure. Users of this European Standard should be aware that more detailed national standards and/or code of practice may exist in the CEN member countri
24、es. This European Standard is intended to be applied in association with these national standards and/or codes of practice setting out the above-mentioned basic principles. In the event of conflicts in terms of more restrictive requirements in national legislation/regulation with the requirements of
