Quality Crimp Handbook
SECTION 7
MEASUREMENT
Pull Force Testing
1. Cut wire length to approximately 150mm (6”) long.
2. Strip one end to 13mm (.50”), or long enough so no
wire insulation is under the insulation grip, or
loosen the insulation crimp so it has no grip on the
insulation of the wire.
3. Terminate the appropriate terminal to the wire to
the nominal crimp height.
4. Visually inspect the termination for bell mouth, wire
brush and cut strands.
5. Set pull tester to 254mm per minute (1.00" per
minute). For most applications, a higher rate will
not have a significant impact on the data. The
slower rate prevents a sudden application of force
or jerking that snaps strands. Verify higher pull
rates with data taken at 1.00” per minute.
6. If necessary, knot the un-terminated end of the wire
(If insulation slips on wire).
7. Regardless of pull tester type, both wire and
terminated end must be securely clamped. (Note:
Clamp terminal contact interface, do not clamp
conductor crimp)
8. Activate pull test.
a. Record pull force readings. A minimum of five
pull force measurements should be done to
confirm each set-up. A minimum of 25 readings
should be taken for determining process
capability.
b. Compare lowest reading to minimum pull force
specification.
Note: High variability and lower value of C pk (see
section 8 for explanation of C pk ) are common
when two wires are crimped together. The
variability is due to more variation in conductor
brush, conductor bell mouth and fewer strands of
one wire being in contact with the serrations on the
terminal barrel. A double wire crimp is considered
no better than the smallest wire crimped. Higher
pull force readings can be seen if both wires are
gripped and pulled exactly together. Pulling each
wire individually will result in a much lower pull
force reading. If both wires are of the same size,
the top wire will normally result in a lower reading than
the bottom wire due to the effects of the terminal
serrations.
Wire Chart
Note: Pull force has only a minimum specification. For C pk
calculations, the average reading is assumed nominal and
the upper specification limit is set so C p and C pk are equal.
High pull force readings that increase the standard
deviation can lower C pk even if the mean and lowest
reading are increased.

Crimp Height Testing
1. Complete tool set-up procedure.
2. Crimp a minimum of five samples.
3. Place the flat blade of the crimp micrometer across the
center of the dual radii of the conductor crimp. Do not
take the measurement near the conductor bell mouth.
4. Rotate the micrometer dial until the point contacts the
bottom radial surface. If using a caliper, be certain not
to measure the extrusion points of the crimp.
5. Record crimp height readings. A minimum of five crimp
height readings is necessary to confirm each set-up. A
minimum of 25 readings is necessary to determine
capability.
6. Check crimp height every 250 to 500 parts throughout
the run.
