45、has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive(s). For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this document. The main technical c

46、hanges that have been made since the latest edition are as follows: the merging of EN 12864, EN 13785 and EN 13786 and their amendments; the extension of the scope to adaptors; the addition of requirements for taking into account pressure loses of gas installations; the removal from this standard of

47、 drawing of connections described in other standards; the improvement of testing methods; additional corrections. Change-over devices and adaptors within the scope of this standard, are not covered by the EU Directive for gas appliances (2009/142/EC). Items relating to quality assurance systems, pro

48、duction testing and particularly certificates of conformity are not covered in this standard.
