This European Standard shall be given the status of a nat
20、ional standard, either by publication of an identical text or by endorsement, at the latest by December 2009, and conflicting national standards shall be withdrawn at the latest by December 2009. This document supersedes EN 12807:2001. The main technical changes are a widening of the range of materi
21、als permitted, reference to the latest EN brazing standards, a reduction in the minimum required burst pressure from 50 bar to 35 bar and simplification of the marking requirements by reference to EN 14894. This document has been prepared under a mandate given to CEN by the European Commission and t
22、he European Free Trade Association, and supports essential requirements of EU Directive(s).
