17、 (E) 4 European foreword This document (EN 10152:2017) has been prepared by Technical Committee ECISS/TC 109 “Coated and uncoated flat products to be used for cold forming”, the secretariat of which is held by AFNOR. This European Standard shall be given the status of a national standard, either by

18、publication of an identical text or by endorsement, at the latest by July 2017, and conflicting national standards shall be withdrawn at the latest by July 2017. 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 hel

19、d responsible for identifying any or all such patent rights. This document supersedes EN 10152:2009. According to the CEN-CENELEC Internal Regulations, the national standards organisations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia,

20、Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the Un

BS EN 10152:2017EN 10152:2017 (E) 5 1 Scope This European Standard specifies requirements for continuously electrolytic (or produced with an alternative process on cold rolled finish substrate) zinc coated cold rolled flat products of low carbon steels suitable for cold forming accordi

22、ng to Table 1 in rolled widths 600 mm and thicknesses from 0,35 mm up to below and including 3 mm, delivered as strip (in coil form), sheet, slit strip or cut lengths obtained from slit strip or sheet. NOTE 1 This European Standard can also be applied to continuously electrolytic zinc coated flat pr

23、oducts of: a) steels according to EN 10139 (cold rolled strip in rolled widths 600 mm),b) steels normally characterized by minimum yield strength or minimum tensile strength values inaddition to formability parameters, e.g. 1) steels with high yield strength and improved formability according to EN

24、10268 (cold rolled flat products), 2) multiphase steels (cold rolled or hot rolled) according to EN 10338, 3) steels for construction according to national or regional standards (see e.g. DIN 1623). NOTE 2 By agreement at the time of enquiry and order this European Standard can be applied to continu

25、ously electrolytic zinc coated hot-rolled steel flat products (e.g. according to EN 100251 and 2, EN 10111, EN 101491 to EN 101493, etc.). NOTE 3 As the mass of the zinc coating applied is relatively small, the material is not intended to withstand outside exposure without further chemical treatment

26、 and painting. NOTE 4 The products covered by this European Standard can be used as substrates for organic coated flat products specified in EN 10169 for building and general engineering applications. 2 Normative references The following documents, in whole or in part, are normatively referenced in
