If the crimp passes the bend test, the insulation crimp must be tested by pulling the wire from the terminal,
splice, or end cap. If the wire insulation is only slightly deformed, the crimp is correct. Figure 8, Detail B
shows a desired crimp, providing adequate support without damage to either the insulation or the wire
conductor(s). If there is visible damage, such as tearing or piercing of the insulation, the crimp is too tight,
and the tooling must be adjusted to produce a looser insulation crimp. Figure 8, Detail C shows a crimp
that is too tight, damaging the insulation and possibly breaking wire conductor(s) or reducing circular mil
area (CMA) by wire extrusion.

3.6. Tensile Strength
Crimped terminals, splices, or end caps should hold the wire conductor(s) firmly and have a pull--test tensile
value meeting that specified in the table in Figure 7.
Adjust tensile testing machine for head travel of 25.4 [1.0] per minute. Directly and gradually apply force for 1 minute.
