BRITISH STANDARD BS EN 10079:2007 Definition of steel products The European Standard EN 10079:2007 has the status of a British Standard ICS 01.040.77; 77.140.01 BS EN 10079:2007 This British Standard was published under the authority of the Standards Policy and Strategy Committee on 30 April 2007 © BSI 2007 ISBN 978 0 580 50483 9 National foreword This British Standard was published by BSI. It is the UK implementation of EN 10079:2007. It supersedes BS EN 10079:1993 which is withdrawn. The UK participation in its preparation was entrusted to Technical Committee ISE/5, Technical delivery conditions, classification and designation of steels. A list of organizations represented on ISE/5 can be obtained on request to its secretary. This publication does not purport to include all the necessary provisions of a contract. Users are responsible for its correct application. Compliance with a British Standard cannot confer immunity from legal obligations. Amendments issued since publication Amd.

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of an identical text or by endorsement, at the latest by September 2007, and conflicting national standards shall be withdrawn at the latest by September 2007. This document supersedes EN 10079:1992. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom. EN 10079:2007 (E) 4 Introduction There are various classification systems existing in Europe but this European Standard only deals with definitions for steel products manufactured by or used in the steel industry or by its customers. For example, Annex B provides guidance on the definition systems used in the former European Coal and Steel Community (ECSC) Treaty as well as the Statistical office of the European Communities and of the Harmonised Commodity Description and Coding System. The entries that are presented in this European Standard have been ordered systematically, and have been grouped by steel products according to: shape and dimensions e.g. flat products, long products, heavy sections; appearance and surface condition e.g. coated flat products, bright products. This European Standard also contains an alphabetical index, which has been included at the end of this document. EN 10079:2007 (E) 5 1 Scope This European Standard defines terms for steel products according to: a) shape and dimensions; and b) appearance and surface condition. NOTE 1 Although the products are generally defined independently of their end uses or manufacturing processes, it has sometimes been necessary to make reference to these criteria. NOTE 2 All dimensions given in this European Standard are nominal. 2 Normative references The following referenced documents are indispensable for the application of this document.
