ASSOCIATED MATERIALS
 Caliper
A gauge, consisting of two opposing blades, used for measuring
linear dimensional attributes.
 Eye Loop
This is a magnification tool,
normally 10 times power or
greater, which is used in the
aid visual evaluation of a
crimp termination.
 Crimp Micrometer
This is a micrometer specifically designed to measure crimp
height. The measurement is taken in the center of the crimp so
the conductor bell mouth does not influence it. It has a thin
blade that supports the top of the crimp while a pointed section
determines the bottom radial surface.
 Ruler (Pocket Scale)
This is used to estimate the five-piece measurement of bell mouth,
cut-off tab, conductor brush, wire position, and strip length. The
recommended maximum resolution is 0.50mm (.020”).
 Pull Tester (Reference Figure 5)
A device used to determine the mechanical strength of a crimp
termination. Most pull testing is done with a device that clamps
the wire, pulls at a set speed, and measures force by means of a
load cell. A pull tester also can be as simple as hanging fixed
weights on the wire for a minimum of one minute.
 Toolmaker’s Microscope
This is used for close visual evaluation and statistical measurement
of bell mouth, cut-off tab, conductor brush, wire position and strip
length.
