STEP 1. Bend lead with fingers, over rounded edge of metal plate as shown in (a).

STEP 2. Center component part in chuck; secure lead in clamp as shown in (b).

STEP 3. Rotate chuck part through 360° at a rate of approximately 5 seconds per 360° rotation. Successive

rotations shall be in alternate directions. A total of three such 360° rotations shall be performed. During

this test, the chuck shall rotate around an axis which is fixed with respect to the padded clamp, or vice

versa. The chuck shall have no appreciable end play during rotation.

NOTES:

1. Dimensions are in inches.

2. Metric equivalents are in parentheses and are given for general information only.
