31、4 Classification and designation 4.1 Classification The grades covered by this European Standard are classified according to the value of the maximum specific total loss in watts per kilogram and according to the nominal thickness of the material (0,35 mm, 0,50 mm, 0,65 mm and 1,00 mm). 4.2 Designat

32、ion For the steel grades covered by this European Standard, the steel names are allocated in accordance with EN 10027-1. The steel numbers are allocated in accordance with EN 10027-2. The steel name comprises the following in the order given: a) capital letter M for electrical steel; b) number of on

33、e hundred times the specified value of maximum specific total loss at 50 Hz, in watts per kilogram and corresponding to the nominal product thickness, at 1,5 T; c) one hundred times the nominal thickness of the material, in millimetres; d) characteristic letter A for non-oriented electrical sheet or

34、 strip supplied in the fully processed state. EXAMPLE Non-oriented electrical steel sheet or strip with a maximum specific total loss at 1,5 T of 2,50 W/kg at 50 Hz, a nominal thickness of 0,35 mm, supplied in the fully processed state: M25035A. 5 Information supplied by the purchaser 5.1 Mandatory

35、information For material to adequately comply with the requirements of this standard, the purchaser shall include the following information in their enquiry or order: BS EN 10106:2015EN 10106:2015 (E) 7 a) quantity; b) type of product (strip or sheet); c) number of this European Standard (EN 10106);

36、 d) steel name or number (see 4.2); e) dimensions of sheets or strips required (including any limitation on the external diameter of a coil) (see 6.2 and 7.2.2); f) axis of coil (horizontal or vertical) (see 6.2); g) internal diameter of coil (508 mm or 610 mm) (see 6.2); h) limitation on the mass o

37、f a bundle of sheets or of a coil or limitation of external diameter (see 6.2); i) limitation of the mass of the packing unit (see 6.2); j) type of inspection procedure, and for specific inspection type of the related document (see 8.1). 5.2 Options A number of options are specified in this standard

38、 and listed in Annex A. 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 5.1). 5.3 Example of an order 18 t strip with 0,35 mm thickness in accordance with EN 10106, made of

39、steel grade M270-35A, delivered in coils with a width of 1 000 mm and a maximum mass of 3 500 kg, vertical coil axis (v), with specific inspection, inspection report 3.1 in accordance with EN 10204: 18 t strip EN 10106 M270-35A 1000 mm max. 3500 kg v 3.1 6 General requirements 6.1 Production process

40、 The production process of the steel and its chemical composition are left to the discretion of the manufacturer. 6.2 Form of supply For sheets the material is supplied in bundles and for strip the material is supplied in coils. The mass of bundles of sheets or the mass and/or the external diameter

41、of coils shall be agreed at the time of enquiry and order. The mass of the package unit shall be agreed at the time of enquiry and order. The recommended value for the internal diameter of coils is 508 mm or 610 mm. The direction of coils, horizontal (h) or vertical (v), shall be agreed at the time

42、of enquiry and order. BS EN 10106:2015EN 10106:2015 (E) 8 Sheets that make up each bundle shall be stacked so that the side faces are substantially flat and approximately perpendicular to the top face. Strip shall be of constant width and wound in such a way that the edges are superimposed in a regu

43、lar manner and that the side faces of the coil are substantially flat. Coils shall be sufficiently tightly wound so that they do not collapse under their own weight. Strip may exhibit welds resulting from removing defective zones if agreed at the time of enquiry and order. If necessary the marking o

44、f welds may be agreed at the time of enquiry and order. For coils containing welds, each part of the strip shall be of the same grade. The edges of parts welded together shall not be so much out of alignment as to affect further processing of the material. 6.3 Delivery condition The material may be

45、supplied either without insulation or with insulation on one or both sides in accordance with EN 10342. lf the material is supplied with insulation, the nature of the insulation, its thickness and properties, the stacking factor and their verification shall be agreed at the time of enquiry and order

46、 (see Annex A, Option 2) and in accordance with the values stated in Table D.1. 6.4 Surface condition The surfaces shall be smooth and clean, free from grease and rust1). Dispersed defects such as scratches, blisters, cracks, etc. are permitted if the products are within the tolerances and if these

47、defects are not detrimental to the correct use of the supplied material. When an insulation coating is present on the surface of the material, it shall be sufficiently adherent so that the coating does not become detached during cutting operations. During the alternating bend test (see 8.4.4.2), the

48、 coating shall not be detached after a bend of 90. If the coating becomes detached during the test, the piece from which the sample was taken shall be subjected to a shearing test. During this test, it shall not be admissible for large pieces of the coating to become detached; however, slight chippi

49、ng of this coating at the shearing edges shall be tolerated. 6.5 Suitability for cutting The material shall be able to be cut or punched at any point and in the usual shapes, thus ensuring accurate working with the correct cutting tools. 7 Technical requirements 7.1 Magnetic properties 7.1.1 General The properties defined in 7.1.2 to 7.1.4 are applicable to products in the delivery conditions defined in 6.3. For coated products, the mass of the insulation coating should be taken into account. 7.1.2 Magnetic polarization The m
