This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by August 2000, and conflicting national standards shall be withdrawn at the latest by August 2000. This European Standard has been p
19、repared 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 standard to those application and product standards which in themselves support an essential safety requirement of a New Approach Directive
20、 and which make reference to this European Standard. 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,
21、 Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom. The European Standard EN 10132, Cold rolled narrow steel strip for heat-treatment - Technical delivery conditions, is subdivided as follows: Part 1: General; Part 2: Case hardening steels;
22、Part 3: Steels for quenching and tempering; Part 4: Spring steels and other special applications.Page 4 EN 10132-2:2000 BSI 05-2000 1 Scope 1.1 This part of EN 10132 applies to non-alloy and alloy cold rolled narrow steel strip for case hardening with thicknesses up to 10 mm for general applications
23、. 1.2 This EN 10132-2 is complemented by EN 10132-1. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For
24、 dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision.
