本欧洲标准描述了CEN/TC 234技术委员会功能性欧洲标准所涵盖的天然气基础设施的压力测试,调试和退役的常规原则,见附件B.他们从详细的操作规范和操作手册中摘录成员国。 本欧洲标准不包括EN 1775所涵盖的安装管道。 规定的程序适用于强度测试,紧密度测试和组合测试。本欧洲标准不涵盖测试压力水平,测试期和验收标准。 附加措施或不同的测试,调试或退役方法可以由个别成员国的立法或管道运营人的酌情决定。 本欧洲标准规定了天然气基础设施的共同基本原则。本欧洲标准的用户应该知道,CEN成员国可能存在更详细的国家标准和/或实践守则。 本欧洲标准旨在与上述基本原则的国家标准和/或业务守则相结合。 在更严格的要求方面出现冲突的情况
This European Standard describes common principles for pressure testing, commissioning and decommissioning of gas infrastructures as covered by the functional 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 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 individual 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 countries. 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 this European Standard, the national legislation/regulation should take precedence as illustrated in CEN/TR 13737. CEN/TR 13737 gives: - clarification of all legislations/regulations applicable in a member state; - if appropriate, more restrictive national requirements; - a national contact point for the latest information.
