16、 22-1: Capacitance tests Test 22a: Capacitance 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
17、all 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 Pub
18、lication(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.
19、IEC 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
20、opinion 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
21、to 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 transpare
22、ntly 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 certi
23、fication 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 sha
24、ll 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 leg
25、al 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 pub
26、lication. 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 60512-22-1 has been prepared by subcommittee 48B: Conn
27、ectors, of IEC technical committee 48: Electromechanical components and mechanical structures for electronic 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 committee has decided that the contents of this publication will remain unchanged until the stabili
30、ty date indicated on the IEC web site under “http:/webstore.iec.ch“ in the data related to the specific publication.

31、T 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 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 det
32、ail specification. The object of this standard is to detail a standard test method to determine the capacitance between conductive elements of connectors. 2 Preparation of the specimen The specimen shall be prepared and mounted according to the detail specification. 3 Test method Any one of the foll
33、owing contact combinations may be measured: a) between one contact and the following parts, all connected to earth at a common point: all other contacts, 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
34、 other contacts, all metal parts, the mounting plate; c) any other measuring point or operating condition as specified by the detail specification. The capacitance shall be measured at a frequency as specified by the detail specification, using a suitable test set, for example a capacitance bridge w
35、hich will ensure an accuracy of 5 %. The preferred measuring frequencies are: 1 kHz 200 Hz, 1 MHz 200 kHz. 4 Requirements The values of capacitance shall not exceed the values specified by the detail specification.
