3.4. Wire Placement
The stripped wire must be inserted into the wire barrel until the wire insulation is against the wire barrel but not
inside it. The wire insulation must be inside the metal sleeve. A gap between the wire insulation and wire barrel
is allowed, but not to exceed the dimension given in Figure 3.

Crimp Inspection Using Micrometer or Comparator

A. Crimp Height
The spring–back of the terminal, splice, or end cap insulation prevents an accurate direct measurement of
crimp height. However, crimping a slug of solder (60% tin and 40% lead) with a diameter slightly larger
than the conductor outside diameter can verify proper termination. The crimp height of the resulting solder
slug can be checked with a standard micrometer or comparator. The measurement must be made over
the most compressed area of the solder slug. See Figure 4.
Transparent Insulation
Window Butt Splice Shown
Some tooling with multiple crimping chambers form an embossed dot code in the terminal, splice, or end cap
insulation that indicates which crimping chamber was used. This dot code can be used as a visual inspection to ensure
that the correct wire size and crimping chamber were used.
