This European Standard shall be given the status of a national standard, either by p
15、ublication of an identical text or by endorsement, at the latest by April 2001, and conflicting national standards shall be withdrawn at the latest by April 2001.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.
16、 This European Standard is considered to be a supporting standard 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 sp
17、ecified in European Standards ; - Part 2 : Steels other than those specified in European Standards ; - Part 3 : Cast irons specified in European Standards ; - Part 4 : Copper alloys specified in European Standards. According to the CENEENELEC Internal Regulations, the national standards organization
18、s of the following countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom. 1 Scope This European Standa
