18、594:2009. Annex J provides details of significant technical changes between this European Standard and the previous edition. There is a complete suite of functional standards prepared by CEN/TC 234 “Gas infrastructure” to cover all parts of the gas infrastructure from the input of gas to the transmi
19、ssion system up to the inlet connection of the gas appliances, whether for domestic, commercial or industrial purposes. Compliance to this standard ensures the interoperability, safety and reliability requirements of pipeline systems. Directive 2009/73/EC concerning common rules for the internal mar
20、ket in natural gas and the related Regulation (EC) No 715/2009 on conditions for access to the natural gas transmission networks also aim at technical safety (security) including technical reliability of the European gas system. These aspects are also in the scope of CEN/TC 234 standardization. In t
21、his respect, CEN/TC 234 evaluated the indicated EU legislation and amended this technical standard accordingly, where required and appropriate. A list of the relevant functional standards prepared by CEN/TC 234 is included in Clause 2 and the Bibliography of this document. CEN/TC 234 will continue i
22、ts work updating this European Standard to the latest developments at regular intervals. In preparing this European Standard, a basic understanding of gas supply by the user has been assumed. Gas infrastructure is complex and the importance on safety of their construction and use has led to the deve
23、lopment of very detailed codes of practice and operating manuals in member countries. These detailed statements embrace recognised standards of gas engineering and specific requirements imposed by legal structures of these member countries. According to the CEN-CENELEC Internal Regulations, the nati
24、onal standards organisations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lit
