15、-2:2000 Foreword This European Standard has been prepared by Technical Committee CENTTC 69 “Industrial valves“, the secretariat of which is held by AFNOR. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the lat
16、est by April 2001, and conflicting national standards shall be withdrawn at the latest by April 2001. This European Standard has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association. This European Standard is considered to be a supporting stan
17、dard to those application and product standards which in themselves support an essential safety requirement of a New Approach Directive and which make reference to this European Standard. EN 1503 comprises four parts : - Part 1 : Steels specified in European Standards ; - Part 2 : Steels other than
18、those specified in European Standards ; - Part 3 : Cast irons specified in European Standards ; - Part 4 : Copper alloys specified in European Standards. According to the CENKENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this Euro
