16、ns 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 another source, it does not relieve the primary supplier of responsi

17、bility 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 testing at all phases of development, production, and field analys

18、is of electrical terminals, connectors, and components that constitute the electrical connection systems in high power road vehicle applications that operates at either 20 V to 600 volts regardless of the current applied or any current greater than or equal to 80 A regardless of the voltage applied

19、These procedures are applicable only to terminals used for In-Line, Header, and Device Connectors and for cable sizes up to 120 mm2(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 mu

20、st pass J1742 requirements, and all other contacts must 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

21、complete subassemblies. This document does not contain 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

22、 Notes for further information. IMPORTANT NOTICE: In 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

23、 they can be considered acceptable for actual vehicle 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

24、the wheel hub. Products certified by their supplier 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 t

25、ests are to be performed on his or her parts and for 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 contai

26、ned in this specification. Any such deviation must be 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 va

27、lue = 85 N. Example 2: SAE J2223-2, Revision 1, paragraph 5.4.9 Cavity Damage Susceptibility not applicable to this design. 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 gi

28、ven in the charts in 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:
