Specific functional requirements for polyethylene pipelines are given in EN 12007-2, for steel pipelines in EN 12007-3 and for the renovation of pipelines in EN 12007-4. Functional recommendations for pipework for buildings are g
8、iven in EN 1775. Functional requirements for service lines are given in prEN 12007-5. Functional requirements for pressure testing, commissioning and decommissioning are given in EN 12327. In Germany, DVGW G 462, G 472 and G 469 apply to the gas infrastructure covered by the present standard. These

31、European Standard describes the general functional requirements for pipelines up to the point of delivery, and also for buried sections of pipework after the point of delivery, for maximum operating pressures up to and including 16 bar for gaseous fuels in accordance with EN 437:1993+A1:2009, Table
32、1. It applies to their design, construction, commissioning, decommissioning, operation, maintenance, renovation, extension and other associated works. This European Standard does not apply to the materials, design, construction, testing and commissioning of gas infrastructures in use prior to the pu
33、blication of this European Standard. However, this European Standard does apply to the operation, maintenance, renovation and extension of all gas infrastructures. Specific functional requirements for polyethylene pipelines are given in EN 12007-2, for steel pipelines in EN 12007-3 and for the renov
34、ation of pipelines in EN 12007-4. Functional recommendations for pipework for buildings are given in EN 1775. Functional requirements for service lines are given in prEN 12007-5. Functional requirements for pressure testing, commissioning and decommissioning are given in EN 12327. Functional require
35、ments for measuring systems are given in EN 1776. Functional requirements for pressure regulating stations are given in EN 12186. Functional requirements for pressure regulating installations are given in EN 12279. Functional requirements for gas transmission are given in EN 1594. This European Stan
36、dard 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 stan
37、dards 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 takes precedence as illustrated
38、 in CEN/TR 13737 (all parts). CEN/TR 13737 (all parts) give: clarification of all legislations/regulations applicable in a member state; if appropriate, more restrictive national requirements; a national contact point for the latest information. 2 Normative references The following documents, in who
