19、n (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 all questions concerning standardization in the electrical and electronic fields. To this end and in ad
20、dition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee inter
21、ested 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. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance wi
22、th 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 opinion on the relevant subjects since each technical committee has representation from all interested
23、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 ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible fo
24、r 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 transparently to the maximum extent possible in their national and regional publications. Any divergence between
25、 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 certification bodies provide conformity assessment services and, in some areas, access to IEC marks of confo
26、rmity. 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 attach to IEC or its directors, employees, servants or agents including individual experts and membe
27、rs 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 fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or
28、 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 publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication ma
29、y be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 60512-22-1 has been prepared by subcommittee 48B: Connectors, of IEC technical committee 48: Electromechanical components and mechanical structures for elect
30、ronic equipment. This standard cancels and replaces Test 22a 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 the following documents: FDIS Report on voting 48B/2158/FDIS 48B/2192/RVD Full information on the voti
31、ng for the approval of this standard can be found in the report on voting indicated in the above table. 60512-22-1 IEC:2010 3 This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. A list of all parts of the IEC 60512 series, under the general title Connectors for elect
32、ronic 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 date indicated on the IEC web site under “http:/webstore.iec.ch“ in the data related to the specific publication. At this
33、 date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. 4 60512-22-1 IEC:2010 CONNECTORS FOR ELECTRONIC EQUIPMENT TESTS AND MEASUREMENTS Part 22-1: Capacitance tests Test 22a: Capacitance 1 Scope and object This part of IEC 60512, when required by the detail
34、 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 object of this standard is to detail a standard test method to determine the capacitance between conductive elements of con
35、nectors. 2 Preparation of the specimen The specimen shall be prepared and mounted according to the detail specification. 3 Test method Any one of the following contact combinations may be measured: a) between one contact and the following parts, all connected to earth at a common point: all other co
36、ntacts, all metal parts, the mounting plate; b) between any two adjacent contacts, the following parts all being connected to earth at a common point: all other contacts, all metal parts, the mounting plate; c) any other measuring point or operating condition as specified by the detail specification
37、. The capacitance shall be measured at a frequency as specified by the detail specification, using a suitable test set, for example a capacitance bridge which will ensure an accuracy of 5 %. The preferred measuring frequencies are: 1 kHz 200 Hz, 1 MHz 200 kHz. 4 Requirements The values of capacitanc
38、e shall not exceed the values specified by the detail specification. 60512-22-1 IEC:2010 5 5 Details to be specified When this test is required by the detail specification, the following details shall be specified: a) preparation of the specimen; b) mounting of the specimen; c) contact combinations
39、to be measured; d) value of the measuring frequency; e) the maximum permitted value(s) of the capacitance(s); f) any deviation from the standard test method. _ 6 60512-22-1 CEI:2010 COMMISSION ELECTROTECHNIQUE INTERNATIONALE _ CONNECTEURS POUR EQUIPEMENTS ELECTRONIQUES ESSAIS ET MESURES Partie 22-1:
40、 Essais de capacit Essai 22a: Capacit AVANT-PROPOS 1) La Commission Electrotechnique Internationale (CEI) est une organisation mondiale de normalisation compose de lensemble des comits lectrotechniques nationaux (Comits nationaux de la CEI). La CEI a pour objet de favoriser la coopration internation
41、ale 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) et des Guides (ci-aprs
42、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, participent galement aux travaux
43、. 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, un accord internatio
44、nal sur les sujets tudis, tant donn que les Comits nationaux intresss sont reprsents dans chaque comit dtudes. 3) Les publications CEI se prsentent sous la forme de recommandations internationales et elles sont agres comme telles par les Comits nationaux de Tous les efforts raisonnables sont entrepr
45、is afin que la CEI sassure de lexactitude du contenu technique de ses publications; la CEI ne peut pas tre tenue responsable de lventuelle mauvaise utilisation ou interprtation qui en est faite par un quelconque utilisateur final. 4) Dans le but dencourager luniformit internationale, les Comits nati
46、onaux de la CEI sengagent, dans toute la mesure possible, appliquer de faon transparente les Publications de la CEI dans leurs publications nationales et rgionales.
