19、with the exception of stainless and heat-resisting steels 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 e

20、xists, particularly the following products: cold rolled non-oriented magnetic steel sheet and strip (EN 10106); grain-oriented magnetic steel sheet and strip (EN 10107); cold rolled electrical non-alloy and alloy steel sheet and strip delivered in the semi-processed state (EN 10341); cold rolled unc

21、oated low carbon and high yield strength steel flat products for cold forming (EN 10131); cold reduced blackplate (EN 10205). 2 Normative references The following referenced documents are indispensable for the application of this document.

23、in EN 10079:1992 shall apply. 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

24、 cut into lengths). By agreement 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. NOTE In the case of narrow widths, strip co

25、nforming to this standard may also be wound in layers and supplied in the form of a bobbin wound coil.

26、 tolerances (A); cut lengths shall be supplied in as produced lengths. 5 Designation Products conforming to this European Standard shall be designated in the following order: a) type of product (narrow strip or cut length); b) reference to this European Standard (EN 10140); c) nominal thickness in m

27、illimetres; d) 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; g) letter B for products ordered with fine tolerances on width; h) nominal length in millimetres (only for cut lengths); i) letter B for pr
