Foreword The text of document 48B/1607/FDIS, future edition 1 of IEC 60512-14-5, prepared by SC 48B, Connectors, of IEC TC 48, Electromechanical components and mechanical structures for electronic equipment, was submitted to the IEC-CENELEC parallel vote and was approved by CENELEC as
16、 EN 60512-14-5 on 2006-04-01. 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 which the EN has to be implemented at national level by publication of an identical national
17、 standard or by endorsement (dop) 2007-01-01 latest date by which the national standards conflicting with the EN have to be withdrawn (dow) 2009-04-01 Annex ZA has been added by CENELEC. _ Endorsement notice The text of the International Standard IEC 60512-14-5:2006 was approved by CENELEC as a Euro

19、d for testing l connectors within the scope of IEC 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 is to detail a standard test method to assess the effectiveness of the sealing of a connector against ingr
20、ess of water by exposure to low pressure whilst immersed in a salt solution. It is particularly, but not exclusively, suitable for mated connector assemblies. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only
21、the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

22、ronic equipment Tests and measurements Part 3-1: Insulation tests Test 3a: Insulation resistance IEC 60512-4-1: Connectors for electronic equipment Tests and measurements Part 4-1: Voltage stress tests Test 4a: Voltage proof 3 Preparations 3.1 Preparation of specimen The specimen shall consist of a
23、mated pair of connectors with its terminations, wired as specified in the detail specification. All wires and cables shall be either sealed or extended outside the test chamber. 3.2 Equipment A vessel containing a 5 % 1 %, by weight, solution of non-iodized (commercial) salt, in distilled or deionis
24、ed water shall be prepared. No contaminant shall be present which would be likely to, or tend to, affect the wetting characterics of the solution. This vessel shall be placed in a chamber capable of being evacuated to a pressure of 2 kPa. EN 60512-14-5:2006 4 3.3 Lubricant or sealing substance If th
25、e detail specification so requires, the specified lubricant or sealing substance shall be applied in the manner given in the detail specification. 3.4 Mounting If mounting of the specimen is appropriate, it shall be as specified in the detail specification. 4 Method 4.1 Procedure The test shall be c
26、arried out at room temperature; the temperature of the specimen and the solution shall not differ by more than 5 C. The specimen shall be submerged in the solution, in such a way that the uppermost point of the specimen is at least 25 mm below the surface of the solution The chamber pressure shall b
27、e reduced from room ambient to 2 kPa 0,1 kPa within a period of 5 min to 15 min and maintained at that pressure for a minimum of 30 min. The chamber pressure shall then be returned to room ambient within a period of 1 min and maintained at that pressure for a minimum of 30 min. This constitutes one
28、cycle. Two additional, identical, cycles shall be carried out. During all three cycles, for the period of intervention and subsequent testing, the specimen shall remain submerged as described above. 4.2 Measurements 4.2.1 Initial measurements Visual examination according to IEC 60512-1-1 shall be ca
29、rried out. There shall be no defects, which would impair the validity of the test. 4.2.2 Test measurements and requirements These tests shall be carried out before the specimen is removed from the salt solution. After testing given in 4.1, insulation resistance in accordance with IEC 60512-3-1 shall
30、 be measured. It shall not be less than that given in the detail specification. After the above test, a voltage proof test in accordance with IEC 60512-4-1 shall be carried out. It shall not be less than that given in the detail specification. 4.2.3 Final measurements Visual examination according to
31、 IEC 60512-1-1 shall be carried out with 10 magnification. Any defects, which would impair the normal functioning of the connector, shall be documented. Special attention shall be given to a) evidence of ingress of the solution; b) evidence of dielectric breakdown. 5 EN 60512-14-5:2006 5 Details to
32、be specified When this test is required by a detail specification, the following shall be given therein: a) preconditioning, if required; b) wiring of the specimen; including wire/cable size and type; c) sealant and/or lubricant to be applied, means and quantity; or state Sealant and/or lubricant no
33、t required; d) minimum value of insulation resistance (after this test); and method; e) proof voltage and maximum permitted leakage current; NOTE The values for d) and e) may be given as a requirement after this test and not be identical to those required for an untested specimen. Measurement test p
34、oints should be given in the detail specification. f) any deviation from the standard test method. _ EN 60512-14-5:2006 6 Annex ZA (normative) Normative references to international publications with their corresponding European publications The following referenced documents are indispensable for th
35、e application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.
