The
14、work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-gover
15、nmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. Th
16、e main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote
17、. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 20860-2 was prepared by Technical Committee ISO/TC 22, Road vehicles. ISO 20860 consists of the

20、e This part of ISO 20860 specifies the tests for male and female connectors of the 50 impedance interface for radio frequency applications in road vehicles, and ensures communication to and within road vehicles. These tests apply to all coaxial connectors for road vehicles with a 50 radio frequency
21、interface in accordance with ISO 20860-1. 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 any amend
22、ments) applies.

27、tor 3.2 Abbreviated terms CT/A continuity totalizer/analyzer NWA network analyzer PC printed circuit RF radio frequency SMA subminiature version A VSWR voltage standing wave ratio 4 Principle Connectors in accordance with ISO 20860-1 need to be tested as one unit consisting of connector and cable. T
28、he cable itself and the quality of the application to the connector can impact the test results. Therefore, only those cables approved by the vehicle manufacturer and those tools and processes recommended by the connector manufacturer shall be used for the preparation of the test samples. These tool
29、s and processes should be as similar as possible to those used for the series production. This instruction shall be applied to PC boards as appropriate, in the case of testing board mount connectors. The test procedures are not intended to test the samples beyond their limits of resilience. After th
30、e tests, the samples shall not show any damage due to the excessive loads applied. The condition of the test samples shall be the same as in regular production. The test samples shall not be specially prepared for the test procedures, apart from as specified in this part of ISO 20860. The test proce
31、dures are planned in such a way that the test samples shall pass through one test sequence. If the vehicle manufacturer so requests, the test samples may be used for several test sequences. All individual requirements shall be fulfilled in that case as well. All test results, laboratory reports and
32、calibration records shall be stored in a central file. Such storage shall be in accordance with established ISO/TS 16949 requirements. 5 Preparation of the test samples 5.1 Dimensional characteristics The part construction of the test samples shall conform to the dimensions, shape and detail attribu
33、tes specified in ISO 20860-1 and as defined in the latest revision of the manufacturers applicable part drawing(s). 5.2 Material characteristics All material used in each test sample shall conform to the specifications in ISO 20860-1 and as defined in the latest revision of the manufacturers applica
34、ble part drawing(s).

35、 reserved 3 5.3 Making of the test samples The quantity and details relative to making the test cable assemblies are given in the corresponding test procedures. The length of the cable assembly is the distance between the two reference planes as defined in ISO 20860-1, with an accuracy of 3 mm. The
36、test samples shall be marked so that they can be identified individually during and after completion of each test sequence. 5.4 Quality test of the test samples All dimensions specified in ISO 20860-1 shall be tested by adequate means. It shall be ensured that the centre contact and the outer contac
37、t of the samples are continuously conductive. NOTE For proof of conductivity, flexible contact parts can be touched, but it is advisable not to expose them to a mating cycle. 5.5 Documentation of the test samples Each single test cable shall be appropriately identified with a unique label, so that t
38、est data can be recorded and retained for evidence. 6 Visual inspection 6.1 Purpose This test shall be used to document the physical appearance of the test samples. A comparison shall then be made with other test samples. In most cases, examinations shall be carried out by a person with normal or co
39、rrected vision and normal colour sensitivity, under cool white fluorescent lighting. Conformity with RAL colours shall be proven by comparison with the RAL colour table (see Reference 1). An identical match is not required, but there shall be clear identification with the intended colour. 6.2 Appara
40、tus 6.2.1 Magnification apparatus 20-times (as required). 6.2.2 Camera, digital camera or video recorder. 6.2.3 RAL colour table or RAL-K5 reference kit (see Reference 1). 6.3 Test samples The visual inspection shall be part of all test procedures. All test samples shall be inspected before and afte
41、r testing. The cables and connectors that belong to the test apparatus shall be inspected and documented. 6.4 Reference samples An additional and appropriately identified untested sample from each test group shall be retained for post-test physical comparisons. Alternatively, photographs and/or vide
42、os are encouraged as a more complete means of documentation instead of the extra sample. 6.5 Procedure Visually inspect each test specimen prior to testing and/or conditioning. Any manufacturing or material defects such as cracks, tarnishing, flash, etc. shall be documented. Special attention shall
43、be paid to contact areas and locking mechanisms.

45、rformance of the samples, shall be allowed. 7 Connector electrical tests 7.1 General Perform the tests in accordance with the corresponding test sequence plans in Clause 10. For each sequential test, the same test samples shall be used. 7.2 Contact resistance 7.2.1 Purpose This test, which conforms
46、to IEC 60512-2-1, determines the electrical resistance of both the outer conductor crimps and corresponding contact interface and the inner conductor crimps and corresponding contact interface. 7.2.2 Apparatus 7.2.2.1 A micro-ohmmeter, which limits the open circuit voltage to 20 mV and limits the cu
47、rrent applied to 100 mA. 7.2.3 Test samples Ten sample test cables, each 100 mm cable dielectric length, with a female connector in accordance with ISO 20860-1 on one end and a male SMA connector on the other end. Ten sample test cables, each 100 mm cable dielectric length, with a male connector in
48、accordance with ISO 20860-1 on one end and a male SMA connector on the other end. 7.2.4 Reference samples Three reference cable assemblies, each 200 mm in length, minus the equivalent length of the mated ISO 20860-1 connectors, with male SMA connectors on both ends. 7.2.5 Procedure Mate two sample cable assemblies. The SMA connectors on the remaining ends shall be connected in an adequate way to the test apparatus. The resistance of the whole cable length between the SMA connectors shal
