19、erference tests Test 24a: Residual magnetism FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on al
20、l questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publi
21、cation(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non-governmental organizations liaising with the IEC also participate in this preparation. IE
22、C collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus of op
23、inion on the relevant subjects since each technical committee has representation from all interested IEC National Committees. 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to
24、 ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparent
25、ly to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC itself does not provide any attestation of conformity. Independent certifi
26、cation bodies provide conformity assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by independent certification bodies. 6) All users should ensure that they have the latest edition of this publication. 7) No liability shall
27、 attach to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for any personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal
28、 fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications. 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable for the correct application of this publi
29、cation. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 60512-24-1 has been prepared by subcommittee 48B: Connec
30、tors, of IEC technical committee 48: Electromechanical components and mechanical structures for electronic equipment. This standard cancels and replaces Test 24a of IEC 60512-9, issued in 1992. The structure of IEC 60512 series is explained in IEC 60512-1-100. The text of this standard is based on t

32、, Part 3. A list of all parts of the IEC 60512 series, under the general title Connectors for electronic equipment Tests and measurements, can be found on the IEC website. The committee has decided that the contents of this publication will remain unchanged until the stability result date indicated
33、on the IEC web site under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. 4 60512-24-1 IEC:2010 CONNECTORS FOR ELECTRONIC EQUIPMENT TESTS AND MEASUREMENTS Part 24-1: Magn
34、etic interference tests Test 24a: Residual magnetism 1 Scope and object This part of IEC 60512, when required by the detail specification, is used for testing connectors within the scope of technical committee 48. It may also be used for similar devices when specified in a detail specification. The
35、object of this standard is to detail a standard method to measure the residual magnetism of a connector after exposure to a specified magnetic field. 2 Preparation of the specimen The connector shall be prepared and mounted in a fixture as required by the detail specification. 3 Test method A magnet
36、ometer with a suitable probe shall be placed horizontally on a non-magnetic support with the probe positioned as far away from the measuring instrument as allowed by the connecting cord. The measuring instrument shall be set to the appropriate scale and the probe oriented so as to read “0“. The spec
37、imen shall be exposed to a magnetic field of approximately 0,5 T (5 000 G) three times. NOTE The specimen should not touch the polar parts of the magnet. Immediately after magnetization, the specimen shall be placed at a distance not exceeding 3 mm from the probe, without touching the probe. The spe
38、cimen shall be oriented so as to obtain a maximum reading on the measuring instrument. 4 Requirements The value measured shall not exceed the maximum value specified by the detail specification. 5 Details to be specified When this test is required by the detail specification, the following details s
39、hall be specified: a) accessories to be fitted on the specimen; b) maximum value of the residual magnetism; c) any deviation from the standard test method. _ 6 60512-24-1 CEI:2010 COMMISSION LECTROTECHNIQUE INTERNATIONALE _ CONNECTEURS POUR QUIPEMENTS LECTRONIQUES ESSAIS ET MESURES Partie 24-1: Essa

La CEI a pour objet de favoriser la
41、coopration internationale pour toutes les questions de normalisation dans les domaines de llectricit et de llectronique. A cet effet, la CEI entre autres activits publie des Normes internationales, des Spcifications techniques, des Rapports techniques, des Spcifications accessibles au public (PAS) e
42、t des Guides (ci-aprs dnomms “Publication(s) de la CEI“). Leur laboration est confie des comits dtudes, aux travaux desquels tout Comit national intress par le sujet trait peut participer. Les organisations internationales, gouvernementales et non gouvernementales, en liaison avec la CEI, participen
43、t galement aux travaux. La CEI collabore troitement avec lOrganisation Internationale de Normalisation (ISO), selon des conditions fixes par accord entre les deux organisations. 2) Les dcisions ou accords officiels de la CEI concernant les questions techniques reprsentent, dans la mesure du possible
44、, un accord international sur les sujets tudis, tant donn que les Comits nationaux de la CEI intresss sont reprsents dans chaque comit dtudes. 3) Les Publications de la CEI se prsentent sous la forme de recommandations internationales et sont agres comme telles par les Comits nationaux de la CEI.
