In particular, it specifies general requirements, the magnetic pro
20、perties, geometric characteristics and tolerances, technological characteristics as well as the inspection procedure. This European Standard applies to materials supplied in the fully annealed condition intended for the construction of magnetic circuits. It does not apply to semi-processed material.
21、 These magnetic materials correspond to C.2.3.2.1 of IEC 60404-1:2000. 2 Normative references The following referenced documents are indispensable for the application of this document.

38、ial 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 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
39、 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 of enquiry and order. Sheets that make up each bundle shall be stacked so that the side faces are substantially flat and approximately perpendicular to t
40、he top face. Strip shall be of constant width and wound in such a way that the edges are superimposed in a regular 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
41、 resulting from removing defective zones if agreed at the time of enquiry and order. If necessary the marking of 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 muc

43、ides 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. 6.4 Surface condition The surfaces shall be smooth and clean, free f
44、rom grease and rust1).Dispersed defects such as scratches, blisters, cracks, etc. are permitted if the products are within the tolerances and if these 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 sha
45、ll be sufficiently adherent so that the coating does not become detached during cutting operations. During the alternating bend test (see 8.4.3.2), the 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 b
46、e subjected to a shearing test. During this test, it shall not be admissible for large pieces of the coating to become detached; however, slight chipping 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
47、 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. NOTE For coated products, the mass of
