19、IONAL ELECTROTECHNICAL COMMISSION _ CONNECTORS FOR ELECTRONIC EQUIPMENT TESTS AND MEASUREMENTS Part 19-1: Chemical resistance tests Test 19a: Fluid resistance of pre-insulated crimp barrels FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardizatio
20、n 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 addition to other activities, IEC publishes Internationa
21、l 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 interested in the subject dealt with may participate in thi
22、s 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 with conditions determined by agreement between the two
23、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 IEC National Committees. 3) IEC Publications have the
24、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 for the way in which they are used or for any misinterpr
25、etation 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 any IEC Publication and the corresponding national or
26、 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 conformity. IEC is not responsible for any services carried
27、 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 members of its technical committees and IEC National Commit
28、tees 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 any other IEC Publications. 8) Attention is drawn to
29、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 may be the subject of patent rights. IEC shall not be he
30、ld responsible for identifying any or all such patent rights. International Standard IEC 60512-19-1 has been prepared by subcommittee 48B: Connectors, of IEC technical committee 48: Electromechanical components and mechanical structures for electronic equipment. This standard cancels and replaces Te
31、st 19a of IEC 60512-9, issued in 1992. The structure of IEC 60512 series is explained in IEC 60512-1-100. 60512-19-1 IEC:2010 3 The text of this standard is based on the following documents: CDV Report on voting 48B/2022/CDV 48B/2112/RVC Full information on the voting for the approval of this standa
32、rd can be found in the report on voting indicated in the above table. 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 electronic equipment Tests and measurements, can be found on
33、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 date, the publication will be reconfirmed, withdrawn, r
34、eplaced by a revised edition, or amended. 4 60512-19-1 IEC:2010 CONNECTORS FOR ELECTRONIC EQUIPMENT TESTS AND MEASUREMENTS Part 19-1: Chemical resistance tests Test 19a: Fluid resistance of pre-insulated crimp barrels 1 Scope and object This part of IEC 60512, when required by the detail specificati
35、on, 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 method to assess the ability of the insulation of pre-insulated crimp barrels to withst
36、and specified fluids under specified conditions. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including an
37、y amendments) applies. IEC 60512-1-1, Connectors for electronic equipment Tests and measurements Part 1-1: General examination Test 1a: Visual examination IEC 60512-4-3, Connectors for electronic equipment Tests and measurements Part 4-3: Voltage stress tests Test 4c: Voltage proof of pre-insulated
38、crimp barrels 3 Preparation of the specimen The specimen shall consist of a crimp contact or a terminal end having a pre-insulated crimp barrel and the appropriate cable/wire and shall be prepared in accordance with the detail specification. The cable or wire, stripped as specified, shall be fitted
39、to the crimp barrel and then crimped in the normal manner. The specimen shall be visually examined with a suitable magnification (e.g. 2 X to 4 X) in accordance with IEC 60512-1-1, test 1a to ensure that the insulation of the crimped barrel is free of splits or cuts which would render the test inval
40、id. 4 Test method 4.1 Conditioning The specimen shall be immersed for 20 h (unless otherwise specified in the detail specification) in the fluid and at the temperature specified in the detail specification. Two specimens shall be immersed in each fluid. No specimen shall be subjected to more than on
41、e fluid. 60512-19-1 IEC:2010 5 4.2 Recovery After removal from the fluid, the specimen shall be allowed to recover for 1 h under standard atmospheric conditions, after which any remaining fluid shall be wiped away. 5 Final measurements 5.1 Visual examination The specimen shall be visually examined w
42、ith a suitable magnification (e.g. 2 X to 4 X) in accordance with IEC 60512-1-1, test 1a. 5.2 Voltage proof After the visual examination, the specimen shall be prepared and then submitted to the voltage proof test as detailed in IEC 60512-4-3, test 4c. The proof voltage shall be as specified in the
43、detail specification. 6 Requirements 6.1 Visual examination There shall be no signs of splitting or other deterioration which would impair use. Discolouration of the insulation is permitted. 6.2 Voltage proof There shall be no breakdown or flashover. 6.3 Details to be specified When this test is req
44、uired by the detail specification, the following details shall be specified: a) preparation of the specimen; b) cable or wire to be used; c) type and die setting of crimping tool; d) fluid and temperature; e) immersion time if other than 20 h; f) proof voltage; g) any deviation from the standard tes
