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 according 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 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 valves 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. 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.
