NOTES AND DEFINITIONS
5.1
Contact Resistance
Differences in contact resistance between various terminal configurations represent changes in bulk
resistance due to longer lengths of current path.
5.2
Contact Retention
Only terminals employing an integral latching mechanism (e.g. barbs, dimples, etc.) for rigid retention
within the housing are subject to this requirement. Terminals which "free-float" within a housing and
are retained by the closure of some form of hinged cover are not included.
5.3
Multi-Position Connector
Assemblies containing more than one jumper shall be subjected to the Group 3 tests; these tests do
not apply to single position devices.
