18、3 Foreword This document (EN 10332:2003) has been prepared by Technical Committee ECISS/TC 24, “Electrical steel sheet and strip qualities - Qualities dimensions, tolerances and specific tests“, the secretariat of which is held by DIN. This European Standard shall be given the status of a national s
19、tandard, either by publication of an identical text or by endorsement, at the latest by November 2003, and conflicting national standards shall be withdrawn at the latest by November 2003. This document is equivalent to IEC 60404-5. Annex A is normative. According to the CEN/CENELEC Internal Regulat
20、ions, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal, Slovakia, Spain, Swede

22、c field strength and also the determination of the demagnetization curve and recoil line of permanent magnet materials, such as those specified in IEC 60404-8-1, the properties of which are presumed homogeneous throughout their volume. The performance of a magnetic system is not only dependent on th
23、e properties of the permanent magnet material but also on the dimensions of the system, the air-gap and other elements of the magnetic circuit. The methods described in this standard refer to the measurement on the magnetic properties in a closed magnetic circuit simulating a ring. 2 Normative refer
24、ences This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text, and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of th
