This European Stand
15、ard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by January 2000, and conflicting national standards shall be withdrawn at the latest by January 2000. This European Standard has been prepared under a mandate given to CE
16、N by the European Commission and the European Free Trade Association. This European Standard is considered to be a supporting standard to those applications and product standards which in themselves support an essential safety requirement of a New Approach Directive and which make reference to this
17、European Standard. This European Standard EN 10277, Bright steel products Technical delivery conditions, is subdivided as follows: Part 1: General; Part 2: Steels for general engineering purposes; Part 3: Free-cutting steels; Part 4: Case-hardening steels; Part 5: Steels for quenching and tempering.
18、 According to the CEN/CENELEC Internal Regulations, the national standards organizations 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, Po
