22、olled Copy, (c) BSI Page 3 EN 10140 : 1996 BSI 1997 1 Scope 1.1 This European Standard applies to cold rolled narrow strip in coils and cut lengths, in thicknesses up to 10 mm and of widths less than 600 mm, made from unalloyed and alloyed steels with the exception of stainless and heat-resisting st
23、eels and the products given in 1.2. The application of this European Standard to products with other dimensions shall be agreed separately. 1.2 This European Standard does not cover cold rolled flat products for which a separate standard already exists, particularly the following products: cold roll
24、ed non-oriented magnetic steel sheet and strip (EN 10106); grain-oriented magnetic steel sheet and strip (EN 10107); semi-processed steel strip for the construction of magnetic circuits (EN 10126 and EN 10165); cold rolled uncoated low carbon and high yield strength steel flat products for cold form
25、ing (EN 10131); cold reduced blackplate (EN 10205). 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate place in the text and the publications are listed hereafter. For d
26、ated 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. For undated references the latest edition of the publication referred to applies. EN 10079Definition of steel products 3 Definiti
27、ons For the purposes of this European Standard, the definitions of cold rolled flat products given in clause 1 are identical to those given in EN 10079. NOTE. In the case of narrow widths, strip conforming to this standard may also be wound in layers and supplied in the form of a bobbin wound coil.
28、4 Form and conditions of delivery 4.1 Form of delivery Cold rolled narrow strip according to this European Standard may be supplied: in coils, of which the dimensions and weight shall be agreed at the time of ordering; or in cut lengths (when coils have been unwound and cut into lengths). By agreeme
29、nt at the time of order, the preferred internal coil diameter is approximately 500 mm or 400 mm. For narrow strip in thicknesses of less than 0.5 mm, smaller internal diameters (e.g. 300 mm or 250 mm) may be agreed separately. 4.2 Condition of delivery Unless the edge condition and tolerances on dim
30、ensions and shape are specified in the order, products shall be supplied with slit edges (GK) and normal tolerances (A); cut lengths shall be supplied in as-produced lengths. 5 Information to be supplied by the purchaser The following information shall be supplied by the purchaser at the time of ord
31、er: a) description of the product (coils or cut lengths); b) number of this European Standard (EN 10140); c) nominal thickness and width in millimetres; d) the symbol GK if slit edges have been ordered; e) nominal length in millimetres (for cut lengths); f) required tolerances: 1) on thickness; 2) o
32、n width; 3) on length; 4) on edge camber; g) type of coil and coil internal diameter. 6 Designation Products conforming to this European Standard shall be designated in the following order (see also clause 5): a) type of product (narrow strip or cut length); b) reference to this European Standard (E
33、N 10140); c) nominal thickness in millimetres; d) the letters B or C for products ordered with fine or precision tolerances on thickness; e) nominal width in millimetres; f) symbols for type of edge if not GK; g) the letter B for products ordered with fine tolerances on width; h) nominal length in m
34、illimetres (only for cut lengths); i) the letter B for products ordered with fine tolerances on length; j) the letters FS for narrow strip or cut length with fine tolerances on edge camber. The designation of products specified in clause 5 shall be followed by the precise designation of the steel gr
35、ade ordered and the surface appearance.

The tolerances in table 5 are only applicable to narrow strip of width at least 10 times the thickness. NOTE 2. For strip in the hardened and t
38、empered condition, edge camber tolerances may be reduced if agreed at the time of ordering. Where it is not practicable to measure over 1000 mm, equivalent tolerances may be calculated from the following formula, the result being rounded to the next highest millimetre: Edge camber tolerance = (non-s
39、tandard length)2 (standard length)2 3 edge camber tolerance in table 5 8.2 Flatness of cut lengths The tolerance on flatness of cut lengths in the direction of rolling shall be 10 mm maximum over 1000 mm. Any other requirements for flatness shall be specially agreed at the time of ordering. If strip
40、 is required to be specially flat across the width, the maximum deviation from flatness and the method of measurement shall be agreed at the time of ordering. 8.3 Out-of-squareness The out-of-squareness of cut lengths in widths less than or equal to 100 mm shall not exceed 1 mm. For cut lengths in w
41、idths exceeding 100 mm, the out-of-squareness shall not exceed 1 % of the actual width of the cut length.

44、f cut lengths The deviation from flatness, p (in the direction of rolling) is taken to be the greatest distance between the cut length resting freely on a flat horizontal base and a rule. The gauge length is fixed at 1000 mm (see figure 1). 9.3 Edge camber The edge camber c is taken to be the greate
45、st distance between a longitudinal edge and a straight line connecting both ends of the gauge length. It is measured on the concave edge of the product. The gauge length is fixed at 1000 mm. For narrow strip, the measurement shall be taken at least 3000 mm from one of the ends of the strip (see figu
46、re 2). 10 Packing Coils shall be secured in such a way that they cannot be damaged or unwind under normal conditions of loading, transportation or careful storage.
