CENELEC members are
9、bound to comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European Standard the status of a national standard without any alteration. Up-to-date lists and bibliographical references concerning such national standards may be obtained on application to th
10、e Central Secretariat or to any CENELEC member. This European Standard exists in three official versions (English, French, German). A version in any other language made by translation under the responsibility of a CENELEC member into its own language and notified to the Central Secretariat has the s

Foreword The text of document 48B/1879/FDIS, future edition 1 of IEC 60512-16-4, prepared by SC 48B, Connectors, of IEC TC 48, Electromechanical components and mechanical structures for electronic
13、 equipment, was submitted to the IEC-CENELEC parallel vote and was approved by CENELEC as EN 60512-16-4 on 2008-07-01. This standard is to be read in conjunction with EN 60512-1 and EN 60512-1-100 which explains the structure of the EN 60512 series. The following dates were fixed: latest date by whi
14、ch the EN has to be implemented at national level by publication of an identical national standard or by endorsement (dop) 2009-04-01 latest date by which the national standards conflicting with the EN have to be withdrawn (dow) 2011-07-01 Annex ZA has been added by CENELEC. _ Endorsement notice The
15、 text of the International Standard IEC 60512-16-4:2008 was approved by CENELEC as a European Standard without any modification. _ 2 BS EN 60512-16-4:2008CONNECTORS FOR ELECTRONIC EQUIPMENT TESTS AND MEASUREMENTS Part 16-4: Mechanical tests on contacts and terminations Test 16d: Tensile strength (cr
16、imped connections) 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 object of this part of IEC 60512 i
17、s to detail a standard test method to determine the tensile strength of a crimped connection. 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 edi
18、tion of the referenced document (including any amendments) applies. IEC 60512-1-1, Connectors for electronic equipment Tests and measurements Part 1-1: General examination Test 1a: Visual examination 3 Preparations 3.1 Preparation of specimen The specimen shall consist of a contact or terminal crimp
19、ed to a conductor. This shall be done in accordance with the relevant detail specification and tooling specifications given therein. If the specimen has a cable insulation support or any other clamping device not part of the conductor crimp, this shall be rendered inoperative such that it has no inf
20、luence on the test. Any preconditioning required by the detail specification shall be applied. NOTE It may be convenient to crimp a specimen to each end of a conductor; if this is done such a specimen shall be considered as one specimen. 3.2 Equipment A tensile testing machine with relevant fixtures
21、 able to comply with the test procedure herein detailed shall be required. 3.3 Mounting If mounting of the specimen is appropriate, it shall be as specified in the detail specification. The specimen shall be fixed in the jaws of a tensile testing machine such that the crimp barrel of the specimen is
22、 nor damaged or otherwise affected by the jaws. The fixing of the specimen shall be such that the tensile load is applied axially to the crimped connection under test. 3 BS EN 60512-16-4:20084 Test method The testing machine head, travelling at a rate of between 25 and 50 mm/min, shall apply tension
23、 to the specimen until the conductor is pulled out of the crimp barrel or the wire or the specimen breaks. 5 Measurements and requirements 5.1 Before testing Visual examination according to IEC 60512-1-1 shall be carried out. 5.2 During testing The load to cause breakage shall be recorded. Also, the
24、 testing machine head rate of travel in mm/min shall be recorded. NOTE The elongation versus load graph may be of interest to users. However, this information is not a requirement of this part of IEC 60512. 5.3 After testing Visual examination according to IEC 60512-1-1 shall be carried out. The nat
25、ure and characterics of the breakage shall be recorded. 6 Details to be specified When this test is required by a detail specification, the following shall be given therein: whether preconditioning is required; cable/wire/conductor size(s) to be used; details of assembly and/or crimping tooling; whe
26、ther a lubricant, including that for assembly and/or crimping tooling, is to be used; whether special mounting of the specimen is required; number of specimens to be tested; minimum ultimate load (if none is specified the values in IEC 60352-2 shall be referenced); any deviation from the standard te
27、st method. 4 BS EN 60512-16-4:2008Bibliography IEC 60352-2, Solderless connections Part 2: Crimped connections General requirements, test methods and practical guidance _ 5 BS EN 60512-16-4:2008NOTE Harmonized as EN 60352-2:2006 (not modified).
