BS EN 12007-1:2012EN 12007-1:2012 (E) 5 1 Scope This 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 o
24、perating pressures up to and including 16 bar for gaseous fuels in accordance with EN 437:1993+A1:2009, Table 1. It applies to their design, construction, commissioning, decommissioning, operation, maintenance, renovation, extension and other associated works. This European Standard does not apply t
25、o the materials, design, construction, testing and commissioning of gas infrastructures in use prior to the publication of this European Standard. However, this European Standard does apply to the operation, maintenance, renovation and extension of all gas infrastructures. Specific functional requir
26、ements 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 given in EN 1775. Functional requirements for service lines are given in prEN 12007-5. Functional
27、requirements for pressure testing, commissioning and decommissioning are given in EN 12327. Functional requirements for measuring systems are given in EN 1776. Functional requirements for pressure regulating stations are given in EN 12186. Functional requirements for pressure regulating installation
28、s are given in EN 12279. Functional requirements for gas transmission are given in EN 1594. 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
29、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 t
30、he requirements of this European Standard, the national legislation/regulation takes precedence as illustrated 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 requirement
