is
not required on interior strands of the cable, chemical conversion coating in accordance with MIL-DTL-
5541, class 3 shall be applied after brazing. Inert gas welding using aluminum based solder or other
means of termination may be used only if approved by the qualifying activity. Aluminum
terminals may be crimped to the cable to facilitate dip brazing. Over crimping shall be avoided.
5/ Bonding jumper types J, K, and L are intended for use on aircraft structures where they are
subjected to continuous and/ or excessive vibrations.
6/ Static charge bonding types I and J are used for static charge bonding applications. Static charge
bonding types I and J shall not be used for lightning protection bonding, which requires conductor
sizes of 12 AWG or larger.

2/ Alternate crimping tools which use the specified dies of this table or qualified class II copper terminal
lugs in accordance with SAE-AS7928/1 (crimped with the tools and dies used t o obtain the class II
terminal lug approval), may be used to facilitate high volume production of copper jumpers. However,
either of these options must be pre-approved by the qualifying activity before qualification tests are
initiated on samples produced using these termination options.
