During the 14th COCOR meeting on 27 and 28 May 1993 in Brussels, ECISS/TC 27 was charged to prepare an amendment of EN 10142 in order to work in the new designations according to EN 10027 : Part 1 and ECISS Information Circular IC 10 as well as the steel numbers according to EN 10027 : Part 2. It is intended to issue a second version of EN 10142 as soon as this amendment is adopted. This amendment to European Standard EN 10142 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of an identical text or by endorsement, at the latest by December 1995, and conflicting national standards shall be withdrawn at the latest by December 1995.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 10142: Austria, Belgium, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and 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 ( 600 mm width). The types of coating, coating masses and coating finishes available, and surface qualities are given in tables 2 to 4 (see also 5.2 to 5.4). 1.2 The products covered by this European Standard are suitable for applications where suitability for forming 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). 1.3 This European Standard is not applicable to ± continuously hot-dip zinc coated structural steel strip and sheet (see EN 10147); ± electrolytically zinc coated cold rolled steel flat products (see EN 10152); ± continuously organic coated (coil coated) steel flat 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 points in the text and the publications are listed hereafter. Subsequent amendments to, or revisions of, any of these publications apply to this European Standard only when incorporated in it by amendment or revision. In the case of undated references, the most recent edition of the publications referred to applies. EN 10002-1Metallic materials.

In this case, wide strip steel is continuously hot-dip coated; the zinc content of the bath shall be at least 99 %. 3.2 coating mass Total mass including both surfaces (expressed in grams per square metre). 4 Designation 4.1 The steel names are allocated in accordance with EN 10027-1 and ECISS Information Circular IC 10; the steel numbers are allocated in accordance with EN 10027-2. 4.2 The products covered by this European Standard shall be designated as follows in the order given: a) type of product (e.g. strip, sheet or cut length); b) number of this standard (EN 10142); c) steel name or steel number and symbol for the type of hot-dip coating as given in table 1; d) number denoting the nominal mass of coating (e.g. 270 = 270 g/m2including both surfaces, see table 4); e) letter denoting the coating finish (N, M or R, see tables 2 and 3); f) letter denoting the surface quality (A, B or C, see tables 2 and 3). g) letter denoting the surface treatment (C, O, CO or U, see 5.5).
