It supersedes BS EN 10027-1:2005

2、which is withdrawn.BSI, as a member of CEN, is obliged to publish EN 10027-1:2016 as a British Standard. However, attention is drawn to the fact that during the development of this European Standard, the UK committee voted against its approval as a European Standard.The UK committee suggested that a

3、mendments be made to Table 1 of EN 10027-1:2016 to address the differences in mechanical and physical properties between hot-finished and cold-formed structural hollow sections. Currently, despite there being different design rules for these products within Eurocode 3 Design of Steel Structures and

4、Eurocode 4 Design of Composite and Steel Structures, both hot-finished and cold-formed hollow sections have exactly the same steel names. The UK proposal was for this to be changed to enable a clear differentiation between the two products and hence eliminate any danger that an incorrect product mig

5、ht be supplied or used in a structure. However, as the changes requested by the UK committee were not adopted, the committee advises users of structural hollow sections to apply suitable checks to ensure that they have been supplied with the correct products, which are properly CE marked and certifi

6、ed in accordance with the European Commission Construction Products Regulation.The UK participation in its preparation was entrusted to Technical Committee ISE/100, Steel, General Issues.A list of organizations represented on this committee can be obtained on request to its secretary.This publicatio

21、100 “Iron and steel - General issues”, the secretariat of which is held by BSI. 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of an identical text or by endorsement, at the latest by April 2017, and conflicting national standards shall be withdrawn at

22、 the latest by April 2017. This document supersedes EN 10027-1:2005. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN shall not be held responsible for identifying any or all such patent rights. According to the CEN-CENELEC Int

23、ernal Regulations, the national standards organisations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland,

24、Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom. EN 10027-1:2016 (E)BS EN 10027-1:20161 Scope 1.1 This European Standard specifies rules for designating steels by means

25、 of symbolic letters and numbers to express application and principal characteristics, e.g. mechanical, physical, chemical, so as to provide an abbreviated identification of steels. NOTE In the English language the designations covered by this European Standard are known as “steel names”; in the Fre

26、nch language as “designation symbolique”; in the German language as “Kurznamen”. 1.2 This European Standard applies to steels specified in European Standards (EN), Technical Specifications (TS), Technical Reports (TR) and CEN members national standards. 1.3 These rules may be applied to non-standard

27、ized steels. 1.4 A system of numerical designation of steels known as steel numbers is specified in EN 10027-2. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the e

28、dition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 10020:2000, Definition and classification of grades of steel EN 10027-2, Designation systems for steels - Part 2: Numerical system EN 10079:2007, Definition of steel pro

29、ducts 3 Terms and definitions For the purposes of this document, the terms and definitions given in EN 10020:2000 and EN 10079:2007 apply. 4 Principles 4.1 A unique steel name There shall be one unique steel name for each steel. 4.2 Formulation of steel names Steel names allocated in accordance with

30、 this European Standard shall comprise principal symbols as specified in 7.1. In order to avoid ambiguity, it may be necessary to supplement these principal symbols by additional symbols identifying additional characteristics of the steel or steel product, e.g. suitability for use at high or low tem

31、peratures, surface condition, treatment condition, de-oxidation. These additional symbols are given in 7.2. EN 10027-1:2016 (E)BS EN 10027-1:2016Unless otherwise specified in this European Standard the symbols used in the steel name shall be written without spaces. 4.3 Allocation of steel names 4.3.

32、1 For steels specified in European Standards (EN), Technical Specifications (TS) and Technical Reports (TR), steel names shall be allocated by the ECISS Technical Committee concerned. 4.3.2 For steels specified in CEN members national standards and for other steels, steel names shall be allocated by

33、 or under the responsibility of the national standards body concerned. So as to avoid a variety of steel names being assigned to essentially the same steel, the European Registration Office as provided for in EN 10027-2 shall, when a steel number is applied for, cooperate with the national standards

34、 body concerned to ensure uniform steel names. 4.4 Consultation Where there are difficulties or disputes in establishing steel names ECISS/TC100 shall be consulted and shall advise accordingly. 5 Reference to product standards The complete designation of a steel product where quoted in orders or sim

35、ilar contractual documents shall include, in addition to the steel name, an indication of the technical delivery requirement in which the steel is specified. For steels specified in standards this shall be the reference number of the relevant product standard. Details of the structures of the steel

36、name for the steel or steel product shall be provided in the relevant product or dimensional standard. 6 Classification of steel names For the purposes of designation, steel names are classified into two main categories: Category 1: steels designated according to their application and mechanical or

37、physical properties (see 7.3). Category 2: steels designated according to their chemical composition (see 7.4). 7 Structure of steel names 7.1 Principal symbols Principal symbols for steels designated according to steel application and its mechanical and physical properties shall be assigned in acco

38、rdance with 7.3. Principal symbols for steels designated according to the chemical composition of the steel shall be assigned in accordance with 7.4. Where a steel is specified in the form of a steel casting, its name as specified in Tables 1 to 15 shall be preceded by the letter G. Where a steel is

39、 produced by powder metallurgy, its name as specified in Tables 14 and 15 shall be preceded by the letters PM. EN 10027-1:2016 (E)BS EN 10027-1:20167.2 Additional symbols Additional symbols may be added to the principal symbols and assigned in accordance with 7.3 and 7.4. Additional symbols are divi

40、ded into two groups, i.e. group 1 and group 2 (see 7.3 and 7.4). If the symbols for group 1 are inadequate to describe the steel fully, then additional symbols from group 2 may be added. Symbols of group 2 shall only be used in conjunction with and follow symbols of group 1. Further additional symbo

41、ls for steel products may follow the additional symbols of group 1 and group 2 and shall be selected in accordance with 7.3 and 7.4 from Tables 16, 17 and 18. These symbols shall be separated from preceding symbols by the plus sign (+). Additional symbols selected from Tables 16, 17 and 18 may be ad

42、ded to steel numbers allocated in accordance with EN 100272 and, when used, separated from the steel number by the plus sign (+). 7.3 Steels designated according to their application and mechanical or physical properties The designation of steel according to their application and mechanical or physi

43、cal properties shall be made in accordance with Table 1 to Table 11.
