37、3.2 edge camber greatest distance between a longitudinal edge of the sheet and the line joining the two extremities of the measured length of this edge 4 Classification The grades covered by this European Standard are classified according to the maximum value of the specific total loss, in watts per

38、 kilogram, and according to the nominal thickness of the material (0,05 mm; 0,10 mm; 0,15 mm; 0,20 mm; 0,25 mm, 0,27 mm, 0,30 mm and 0,35 mm for non-oriented steel, respectively 0,05 mm; 0,10 mm, 0,15 mm and 0,18 mm for grain-oriented steel). 5 Designation The conventional designation of the differe

39、nt grades comprises the following in the order: a) the characteristic letters: 1) NO for non-oriented strip and sheet; 2) GO for grain-oriented strip and sheet; b) 100 times the nominal thickness of the material, in millimetres; EXAMPLE NO 20: non-oriented strip in thickness of 0,20 mm. c) maximum s

40、pecific total loss by given frequency in cases where steel grades with different values for maximum specific total loss per nominal thickness are stated (see Table 2). 6 Information to be supplied by purchaser 6.1 Mandatory information For material to comply adequately with the requirements of this

41、standard, the purchaser shall include the following information in his enquiry or order: a) the quantity required (including any limitations on the mass of a coil) (see 7.2); b) type of product (strip or sheet); c) number of this European Standard (EN 10303); d) the grade designation of the material

42、, in accordance with Clause 5; e) the dimensions of strips required (including any limitations of the internal and external diameter of a coil) (see 7.2 and 8.3.2); f) the inspection procedure required including the nature of the related documents (see 9.1); DIN EN 10303:2016-02 EN 10303:2015 (E) 7

43、6.2 Options A number of options are specified in this standard and listed below. lf the purchaser does not indicate his wish to implement one of these options, the products shall be supplied in accordance with the basis specification of this standard (see 6.1): 1) presence of welds or interleaves an

44、d their optional marking (see 7.2); 2) compatibility of the surface insulation coating (see 7.4); 3) residual curvature (see 8.3.5); 4) insulation coating resistance (see 8.4.4). 5) mechanical properties for non-oriented products (see Table D.1) 7 General requirements 7.1 Production process The prod

45、uction process of the steel and its composition are left to the discretion of the manufacturer. 7.2 Form of supply The material is supplied in coils. The mass of coils shall be agreed at the time of ordering. The recommended value for the internal diameter of coils is approximately 400 mm except for

46、 non-oriented strip in thickness of 0,20 mm; 0,25 mm, 0,27 mm, 0,30 mm and 0,35 mm, and grain-oriented strip in thickness of 0,18 mm for which the recommended internal diameter is approximately 500 mm. The strip shall be of constant width and wound in such a manner that the edges are super-imposed i

47、n a regular manner and that the side faces of the coil are substantially flat. The coils shall be sufficiently tightly wound that they do not collapse under their own weight. The strip can occasionally exhibit welds or interleaves resulting from the removal of defective zones, subject to prior agree

48、ment between the parties. The value of the additional thickness due to the weld is subject to the agreement. If necessary the marking of welds or interleaves may form the subject of a special agreement. For coils containing repair welds or interleaves, each part of the strip shall be of the same gra

49、de material. The edges of parts welded together shall not be so much out of alignment as to affect the further processing of the material. 7.3 Delivery condition Products according to this standard are delivered either with a coating on one or on both sides but also without coating. Different types of coating can be provided. DIN EN 10303:2016-02 EN 10303:2015 (E) 8 7.4 Surface condition The surfaces shall be smooth and clean and free from grease and rust.1)Dispersed
