This European Standard applies to all valves (plug valves, ball valves, gate valves and check valves) used in onshore transmission pipelines for transport of natural gas in accordance with EN 1594. It 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. Excluded from the scope are control valves, safety valves and all valves <= DN 50. 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 H. This European Standard makes reference to ISO 14313. All the requirements of ISO 14313 should be met unless otherwise stated. Paragraphs marked with a dot [•] indicate requirements which are identical to ISO 14313. In the case of conflict between European and International Standard, the European Standard takes precedence. Additional national requirements and tests in accordance with individual national legal regulations not yet harmonized may be necessary and are to be advised in the purchase order.
