19、he development of a European performance standard of valves for use in pipelines for transportation of natural gas in accordance with EN 1594. The significant properties of valves designed for a special application are defined by performance requirements accompanied by the description of tests to be

20、 carried out: by the manufacturer on the product during the manufacture; and by an independent accepted body on test samples for certification purposes; to give proof that the valve meets the performance requirements of this European Standard. A type test is included in this European Standard to sat

21、isfy the requirements of EN 1594. BS EN 14141:2013EN 14141:2013 (E) 5 1 Scope This European Standard applies to all valves (plug, ball, gate and check valves) used in onshore transmission pipelines for transport of natural gas in accordance with EN 1594, but with a differing temperature range accord

22、ing to the following three classes in accordance with EN 682: 1) - 10 C to 60 C; 2) - 20 C to 60 C; 3) the range stated by the purchaser for special design. This European Standard comprises all valves which are components of the pipeline. This European Standard specifies valves for pipelines with a

23、maximum operating pressure (MOP) over 16 bar. Control valves and safety valves are excluded from the scope of this European Standard. This European Standard specifies requirements and appropriate verification tests carried out during production and for certification purposes to verify that the valve

24、s conform to the requirements. A summary of the product and type tests is given in Annex G. This European Standard makes reference to EN 13942. All the requirements of EN 13942 should be met unless otherwise stated. Paragraphs marked with a dot indicate requirements which are identical to EN 13942.

25、Additional national requirements and tests in accordance with individual national legal regulations not yet harmonised may be necessary and are to be advised in the purchase order. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and ar
