15、The 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-g
16、overnmental, 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
17、. The 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
18、vote. 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
19、 the following parts, under the general title Road vehicles 50 impedance radio frequency connection system interface: Part 1: Dimensions and electrical requirements Part 2: Test procedures BS ISO 20860-2:2009INTERNATIONAL STANDARD ISO 20860-2:2009(E) ISO 2009 All rights reserved 1Road vehicles 50 im

27、sion 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. The cable itself and the quality of the application to the connector can impact the test results. Therefore, only those cables approved by th
28、e vehicle manufacturer and those tools and processes recommended by the connector manufacturer shall be used for the preparation of the test samples. These tools and processes should be as similar as possible to those used for the series production. This instruction shall be applied to PC boards as
29、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 the 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
30、 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 procedures are planned in such a way that the test samples shall pass through one test sequence. If the vehicle manufacturer so requests, the tes
31、t 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 calibration records shall be stored in a central file. Such storage shall be in accordance with established ISO/TS 16949 requirements. 5 Pre
32、paration of the test samples 5.1 Dimensional characteristics The part construction of the test samples shall conform to the dimensions, shape and detail attributes specified in ISO 20860-1 and as defined in the latest revision of the manufacturers applicable part drawing(s). 5.2 Material characteris
33、tics 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 applicable part drawing(s).

34、tails 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 test samples shall be marked so that they can be identified in
35、dividually 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 contact of the samples are continuously conductive. NOTE For proof o
36、f 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 test data can be recorded and retained for evidence. 6 Visual i
37、nspection 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 corrected vision and normal colour sensitivity, under cool white
38、 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 Apparatus 6.2.1 Magnification apparatus 20-times (as required). 6.2.
