8、related component may be represented as having met SAE specifications unless conformance to all applicable requirements of this specification have been verified and documented. All required verification and documentation must be done by the supplier of the part or parts. If testing is performed by a
9、nother source, it does not relieve the primary supplier of responsibility for documentation of all test results and for verification that all samples tested met all applicable Acceptance Criteria. See Section 4. 1. Scope Procedures included within this specification are intended to cover performance
10、 testing at all phases of development, production, and field analysis of electrical terminals, connectors, and components that constitute the electrical connection systems in high power (20 V to 600 V and/or 80 amps) road vehicle applications. These procedures are applicable only to terminals used f
11、or In-Line, Header, and Device Connectors and for cable sizes up to 120 mm 2 (4/0). In cases where power levels are mixed in the same connector, (i.e. sensing or normal 14.5 volt system circuits with High Power Contacts) the High Power Contacts must pass J1742 requirements, and all other contacts mu
12、st pass SAE J2223-2 requirements. The connection system (housing and high power contacts) shall meet J1742 requirements. The requirements and procedures in this document are not intended for connections internal to electrical/electronic modules or complete subassemblies. This document does not conta
13、in a test for EMI/EMC since these parameters must be tested as a combination of cable and connector. These are considered system level requirements. Determination of the need and type of test must be considered at that level. See Appendix C, Design Notes for further information. IMPORTANT NOTICE: In
14、 any intended vehicle application, if the products covered by this specification are, or may be, subjected to conditions beyond those described in this document, they must pass special tests simulating the actual conditions to be encountered before they can be considered acceptable for actual vehicl
15、e application. By way only of example, this includes products that may be subjected to temperatures beyond the extremes of Class 5 in Table 2 of SAE J2223-2, or may be subjected to shock or vibration in the un-sprung portions of a vehicle, such as the wheel hub. Products certified by their supplier
16、as having passed specific applicable portions of this specification are not to be used in applications where conditions may exceed those for which the product has been satisfactorily tested. The Authorized Person is the final authority as to what tests are to be performed on his or her parts and for
17、 what purpose these tests are required. He or she is also the final authority for resolving any questions related to testing to this specification and for authorizing any deviations to the equipment, procedures and/or acceptance requirements contained in this specification. Any such deviation must b
18、e documented and included in the final test report and on the part print. The following are examples of appropriate print notations: Example 1: Test value per SAE J2223-2, Revision 1, paragraph 5.4.2 Connector Mating/Un-mating Force mating force value = 85 N. Example 2: SAE J2223-2, Revision 1, para
19、graph 5.4.9 Cavity Damage Susceptibility not applicable to this design. SAE J1742 Revised DEC2005 - 3 - Agreement to waive or alter test procedures and Acceptance Criteria must be made between customer and supplier. Guidance as to the recommended tests for selected purposes is given in the charts in
20、 Appendix A and B. In the absence of contrary direction from the Authorized Person in the test request/order, all electrical connectors and their associated terminals and other components are required to meet all applicable portions of this document with the following exception: Specific tests that
21、are not required or additional test requirements as specified in any document in the hierarchy of Section 2. 1.1 Rationale Numerous technological advances have been made since the original document was issued. USCAR and SAE have also cooperated on the development of more refined connector test metho
22、ds and acceptance criteria. These changes are reflected in this revision of J1742. 2.
