21、n prepared by Technical Committee CEN/TC 234 “Gas supply”, the secretariat of which is held by DIN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by May 2009, and conflicting national standards sha

22、ll be withdrawn at the latest by May 2009. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. There is a complete suite of functional sta

23、ndards prepared by CEN/TC 234 “Gas infrastructure” to cover all parts of the gas supply system from the input of gas to the transmission system up to the inlet connection of the gas appliances, whether for domestic, commercial or industrial purposes. In preparing this standard, a basic understanding

24、 of gas supply by the user has been assumed. In the event of conflicts in terms of more restrictive requirements in national legislation/regulation with the requirements of this standard, national legislation/regulation takes precedence as illustrated in CEN /TR 13737. NOTE CEN/TR 13737 contains: -

25、clarification of relevant legislation/regulations applicable in a country; - if appropriate, more restrictive national requirements; - national contact point for the latest information. Gas supply systems are complex and the importance on safety of their construction and use has led to the developme

26、nt of very detailed codes of practice and operating manuals in the member countries. These detailed statements embrace recognised standards of gas engineering and the specific requirements imposed by the legal structures of the member countries. According to the CEN/CENELEC Internal Regulations, the

27、 national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Nor

29、ns and assemblies with an operating pressure greater than 0,5 bar and of non-industrial gas installations (residential and commercial) with an operating pressure greater than 5 bar, starting from the outlet of the network operators point of delivery up to the inlet connection to the gas appliance; n

30、ormally the inlet isolation valve. This European Standard also covers the inlet connection to the gas appliance comprising of the pipework that does not fall within the scope of the appliance standard. This standard applies to gas installations operating at ambient temperatures between 20 C and 40 C

31、 and operating pressures up to and including 60 bar. For operating conditions outside these limitations, reference should additionally be made to EN 13480 for metallic pipework. For industrial gas installations up to and including 0,5 bar and for non-industrial (residential and commercial) gas insta

32、llations up to and including 5 bar EN 1775 applies. For gas installations that do not fall within the scope of EN 1775 or other European Standards, this European Standard applies. In this European Standard, the term “gas“ refers to combustible gases, which are gaseous at 15 C and 1 013 mbar absolute

33、 atmospheric pressure. These gases are commonly referred to as manufactured gas, natural gas or Liquefied Petroleum Gas (LPG). They are also referred to as first, second or third family gases (see table 1 of EN 437:2003). LPG storage vessels (including all ancillaries fitted directly to storage vess

34、els) are excluded. Also excluded are LPG installations and sections of LPG installations operating at vapour pressure (e.g. between the storage vessel and its pressure regulator). In this European Standard, all pressures are gauge pressures unless otherwise stated. For gas installations within the s

35、cope of this standard, national legislation and regulations have to be taken into account. Functional requirements for design, selection of materials, construction, inspection and testing of industrial gas installations and assemblies with an operating pressure greater than 0,5 bar and of gas instal

36、lations greater than 5 bar in buildings and areas intended for residential, commercial, public and mixed uses are described in prEN 15001-1. 2 Normative references The following referenced documents are indispensable for the application of this document.
