Abrasion Resistance Test Procedure
7.14.1 Specimen Preparation:
- Cut six straight untwisted specimens (15 inch/380 mm) from finished cable
- Lay specimens flat and parallel on a horizontal steel plate
- Secure each specimen at both ends
- Position abrasion tool (weighted steel cylinder with three parallel teeth) above each specimen center
- Align tool teeth perpendicular to specimen axis
7.14.2 Test Execution:
- Reciprocate specimen plate horizontally at 30 cycles/minute
- Use simple harmonic motion parallel to specimen axes
- Center stroke on abrasion tools (6 inch/150 mm length)
7.14.3 Test Monitoring:
- Begin test with plate at stroke end and counter at zero
- Apply weight to each tool (3 lbf ±0.5 ozf / 13.34 ±0.14 N)
- Lower tools gently onto specimens and begin reciprocation
- Continue until jacket penetration or 70 complete cycles
- Operator must monitor wear, clear debris, and record penetration cycles
Note: Test complies with UL 719 standard for evaluating jacket abrasion resistance on flat cables.
