25、eld 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of an identical text or by endorsement, at the latest by November 2015, and conflicting national standards shall be withdrawn at the latest by November 2015. Attention is drawn to the possibili
26、ty 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. This document supersedes EN 12007-3:2000. Annex D provides details of significant technical changes between this European
27、 Standard and the previous edition. There is a complete suite of functional standards prepared by CEN/TC 234 “Gas infrastructure“ to cover all parts from the input of gas to the transmission system up to the inlet connection of the gas appliances, whether for domestic, commercial or industrial purpo
28、ses. In preparing this standard, a basic understanding of gas infrastructure by the user has been assumed. Gas infrastructure is complex and the importance on safety of its construction and use has led to the development of very detailed codes of practice and operating manuals in the member countrie
29、s. These detailed statements embrace recognized 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 national standards organizations of the following countries are bound to implemen
