This document (EN 10131:2006) has been prepared by Technical Committee ECISS/TC 13 “Flat products for cold working - Qualities, dimensions, tolerances and specific tests”, the secretariat of which is held by IBN. 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of an identical text or by endorsement, at the latest by January 2007, and conflicting national standards shall be withdrawn at the latest by January 2007. This document supersedes EN 10131:1991. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, 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.

For dated references, only the edition cited applies. For undated references the latest edition of the referenced document (including any amendments) applies. EN 10079:1992, Definition of steel products 3 Terms and definitions For the purposes of this European Standard, the terms and definitions given in EN 10079:1992 and the following apply. 3.1 nominal thickness whole specified thickness of the coated or uncoated product NOTE In the case of coated products, it includes both substrate and coating.
4 Designation 4.1 Products conforming to this European standard shall be designated in the following order (see also clause 5): a) type of product (sheet, wide strip, slit wide strip or cut length); b) reference to this European Standard (EN 10131); c) nominal thickness in millimetres; d) letter S for products ordered with special tolerances on thickness; e) nominal width in millimetres;

Wide strip EN 10131-1,20x1500 Steel EN 10130-DC04-A-m EXAMPLE 2 Sheet according to this European standard of nominal thickness 0,80 mm ordered with special thickness tolerance (S), nominal width of 1200 mm with special tolerances on width (S), nominal length of 2500 mm and with special tolerances on flatness in steel DC06-B-g as specified in EN 10130:
Sheet EN 10131-0,80Sx1200Sx2500FS Steel EN 10130-DC06-B-g 5 Condition of delivery 5.1 Flat products according to this European standard may be delivered as follows: a) with normal or special thickness tolerances (see Tables 1 to 4); b) with normal or special width tolerances (see Tables 5 and 6); c) with normal or special length tolerances for sheet or cut lengths (see Table 7); d) with normal or special flatness tolerances for sheet or cut lengths (see Tables 8 and 9); e) with normal or special tolerances on camber for slit strip of width less than 600 mm (see clause 11). 5.2 In the absence of information on the order in respect of the condition of delivery given in 5.1 the flat products shall be delivered with normal tolerances on thickness, width, length, flatness and camber.
6 Tolerances on thickness The thickness may be measured at any point located more than 40 mm from the edges. In the case of slit coils or cut lengths having a width of 80 mm or below, the position of the measurement shall be at the middle axis. The tolerances on thickness shall be as given in Tables 1 to 4 and apply over the whole length. Tolerances more severe than special tolerances may be agreed at the time of the order.
