It supersedes EURONORM 147 (1979) Continuous hot-dip zinc coated unalloyed steel sheet and coil with specified minimum yield strengths for structural purposes; Quality standard. The European Committee for Iron and Steel Standardization (ECISS) has allocated TC 27 the task of transforming EURONORM 147-79 into a European Standard (EN10147). This European Standard EN 10147 was approved by CEN on 30 November 1991. In accordance with the Common CEN/CENELEC Internal Regulations, the following countries are bound to implement this European Standard: Austria, Belgium, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, the Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and United Kingdom. Foreword to Amendment 1 This Amendment 1 to the European Standard EN 10147 has been prepared by Technical Committee ECISS/TC 27, Surface coated steel flat products, of which the secretariat is held by DIN. During the 14th COCOR meeting on 27 and 28 May 1993 in Brussels ECISS/TC 27 was charged to prepare an amendment of EN 10147 in order to work in the new designations according to EN 10027-1 and ECISS Information Circular IC 10 as well as the steel numbers according to EN 10027-2. It is intended to issue a second version of EN 10147 as soon as this amendment is adopted. This amendment to European Standard EN 10147 shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by December 1995, and conflicting national standards shall be withdrawn at the latest by December 1995. According to the CEN/CENELEC Internal Regulations the following countries are bound to implement this Amendment 1 to European Standard EN 10147: Austria, Belgium, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom.

The thickness is the final thickness of the delivered product after zinc coating. This European Standard applies to strip of all widths and to sheets cut from it ($ 600 mm width) and cut lengths ( 3,0 m. In this case, the mechanical property, adhesion of coating and surface condition requirements shall also be agreed at the time of ordering. 1.3 The products covered by this European Standard are suitable for applications where the minimum yield strength values and resistance to corrosion are of prime importance. Corrosion protection afforded by the coating is directly proportional to the mass of coating (see also 5.2.2). 1.4 This European Standard is not applicable to continuously hot-dip zinc coated low carbon steel strip and sheet for cold forming (see EN 10142); electrolytically zinc coated cold rolled steel flat products (see EN 10152); continuously organic coated (coil coated) flat steel products (see EN 10169). 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 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.
