2、01 REVISED DATE: 2008. 10. 21 VERSION: 3 GM DAEWOO Auto & Technology Note: This standard may be applied only for current project (incl. T255 Program). It is Superceded for all future projects and replaced by GMW3191. 1. PURPOSE In these technical delivery conditions the requirements, test conditions

3、 and test method are determined, which must fulfill the plug and socket in the motor vehicle. This specification is valid for plug and socket made by crimp-connection with multiple-fine-and superfinish wires Cu-conductors. At that time, the question is blade-and pin plug connections in single-and mu

4、ltipolar type, which can differ in the technical type according to case of application. Part 1 of this specification determines the requirements valid for plug connections in general. Because the large scope of plug connections is not clearly limited, it is necessary to agree with the manufacturer a

5、bout the requirements already determined in the additional parts, further supplementary requirements and tests for the special purposes. Further requirements on individual plug connections are determined in the follwing stated additional parts for these technical delivery conditions. 2. REMARK Sampl

6、es of material released to this specification shall be tested according to this spec. and approved by GMDAT TECHNICAL CENTER, prior to the commencement of this bulk supplies. In the event of any intentional deviation from the requirement of this spec., it is the sole responsibility of the supplier t

7、o submit the purchaser unsolicited the samples for reapproval by GMDAT TECHNICAL CENTER prior to the commencement of delivery of deviant bulk supplies. 3. TEST SAMPLE AND TEST QUANTITY If nothing else is specified, min. 40 piece plug and sockets with a works test certificate to DIN 50049. 2.3 are to

8、 be delivered for initial sampling and release test according to this specification. It is expected that the values of all required characteristic quantities represent the tolerance range of production scattering width at the presented test samples. If these supposition is not fulfilled by the test

9、samples, the tolerance ranges of production scattering width for all required characteristic quantities must be specified in the works test certificate apart from the individual values.
