Connections for High Voltage On-Board Road Vehicle Electrical Wiring Harnesses—Test Methods and General Performance Requirements
- Ground Vehicle Standard

- Revised

Scope
Procedures included within this specification are intended to cover performance 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 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 must 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 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 Notes for further information.
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 methods and acceptance criteria. These changes are reflected in this revision of J1742.

Issuing Committee
Electrical Distribution Steering Committee
The scope of the Electrical Distribution Systems Steering Committee includes the development and maintenance of standards and recommended practices for automotive power and signal distribution systems used in passenger cars and light duty trucks. The scope includes standards for wiring systems, connection systems, cable, and harness coverings. Standards are developed for all voltage ratings up to but not including ignition cable assemblies and components. The scope does not include circuit protection or switching devices.

* Redlines comparisons are available for those standards
listed in the Revision History that contain a radio button. A
redline comparison of the current version against a revision is
accomplished by selecting the radio button next to the standard and
then selecting 'compare'. At this time, Redline versions only exist
for some AMS standards. SAE will continue to add redline versioning
with ongoing updates to SAE MOBILUS.
