2.1 INSTALLATION TEST PROCEDURE
INSTALLATION TEST PROCEDURE (TBM8S ONLY)
WARNING
SHURE STAKE®SAFETY RELEASE
The TBM8S compression tool is equipped with the Shure Stake®full stroke compelling mechanism. If it
becomes necessary to release the Shure Stake®Mechanism before completion of the crimp cycle, disengage ratchet as follows. Slightly squeeze
handles, and push the dowel pin, releasing the locking mechanism allowing the handles to open.

CAUTION
Care should be taken to strip the insulation of the conductor
without cutting or nicking the conductor strands, as this
condition will result in premature pull-test failures.
Using a tool that has passed the calibration requirements install a
minimum of six (6) terminals for each die nest on the appropriate
wire for which a performance check is required. In order to obtain
valid and consistent results, perform installation procedure as
follows:
1.
Strip conductor approximately 1/4” longer than the connector
barrel. (Strip length for test purposes only. For actual installation,
refer to the instruction sheet supplied with the connectors.)
2. For aluminum conductor, smear a thin layer of joint compound
onto the cable and brush it in with a wire brush or emery cloth.
3. Insert stripped conductor into connector barrel until it
bottoms out.
4. Choose an installing die with the same color marking as the
connector.
5. Locate connector in die grooves of tool, so that die is between
the color code marks for copper and on the color code marks for
aluminium, see graphics below.
6. Some Color Keyed
®
connectors require more than one
compression. Refer to the instruction sheet supplied with
the connectors regarding the number of compressions
required. If more than one compression is indicated, the first
compression should be in the indicated area nearest to the
tongue of a terminal and nearest the center of a splice, and
then working progressively toward the end of the barrel.
7. Squeeze handles fully closed until SHURE STAKE
®
mechanism releases.

1. Install test sample in a tension-testing machine or a suitable pull-test
fixture.
NOTE: The pull is to be exerted gradually. An abrupt pull is not a proper test method.
2. Subject each sample to an axial pull which is to be increased until failure of the
connection occurs. See graphics below.
3. The pull force required to separate a terminal from its associated wire shall be no less
than the minimum pullout (see table on the right).
NOTE: On “C” tap and wire joints, only the smallest wire in each combination is to be
tested for pullout.
