UL 719 Abrasion Resistance Tester Overview
Product Overview
The UL 719 Abrasion Resistance Tester is used to test the jacket abrasion resistance of flat cables. During testing, straight cable specimens are fixed on a horizontal steel plate, while weighted abrasion tools are positioned over the specimens. The specimen plate then reciprocates horizontally so that the cable jacket is subjected to repeated abrasion.
This equipment is suitable for cable manufacturers, third-party laboratories, certification preparation teams, R&D departments and quality control departments that need to verify the mechanical durability of flat cable jackets.
The system provides controlled reciprocating abrasion conditions for repeatable product development, quality inspection and compliance preparation.

Testing Principle and Result Evaluation
The UL 719 Abrasion Resistance Tester evaluates the abrasion resistance of flat cable jackets through repeated reciprocating abrasion. Cable specimens are fixed on a horizontal steel plate, and weighted abrasion tools are positioned above the required test area.
During testing, the specimen plate moves horizontally at 30 times per minute with a 150 mm / approximately 6 inch stroke. The abrasion tool applies a defined load to the cable jacket while the repeated movement rubs the jacket surface under controlled conditions.
The operator should monitor the jacket surface during the test and record whether penetration occurs. The test continues until jacket penetration occurs or the required number of cycles is reached. Final evaluation should follow UL 719 Clause 7.14 and the laboratory acceptance criteria.

Common Error Mitigation
Reliable flat cable jacket abrasion testing depends on correct specimen preparation, tool alignment and stable test movement. Laboratories should avoid:
| ● Using twisted, bent or damaged cable specimens | ● Cutting specimens to the wrong length |
| ● Failing to secure specimens firmly at both ends | ● Allowing the specimen to move during testing |
| ● Misaligning the abrasion tool teeth with the specimen axis | ● Using worn or damaged abrasion tools |
| ● Applying an incorrect test weight | ● Setting the wrong reciprocating speed or stroke length |
| ● Forgetting to reset the counter before testing | ● Recording only pass/fail results without noting the penetration cycle count |
Specimen Preparation and Test Notes
Before testing, straight untwisted cable specimens should be prepared according to the applicable test procedure. The original procedure information describes six straight untwisted specimens of 15 inch / 380 mm cut from finished flat cable.
The specimens should be fixed flat and parallel on the steel plate, with the abrasion tools correctly positioned over the required test area. The counter should be reset before the test starts, and the operator should confirm the test weight, stroke length and reciprocating speed.
During testing, the jacket condition should be monitored until jacket penetration occurs or the specified cycle count is completed. The original procedure describes testing at 30 cycles per minute, with a 6 inch / 150 mm stroke, until jacket penetration or 70 complete cycles are reached.
Maintenance and Documentation Support
| Maintenance:
The test plate, abrasion tools, teeth, fixtures and moving mechanism should be inspected regularly. Worn abrasion tools, loose fixtures or unstable reciprocating movement may affect test repeatability. After testing, cable debris and jacket particles should be removed from the test area. The abrasion tools and steel plate should be kept clean and dry. The test weight, stroke length and movement stability should be checked periodically according to the laboratory procedure. |
For formal laboratory use, recommended documentation includes:
● Equipment specification
● Calibration certificate or inspection record ● Abrasion tool condition record ● Test weight verification record ● Specimen preparation record ● Stroke length and speed setting record ● Cycle count record ● Jacket penetration observation ● Final test report according to laboratory procedure |
Standards Compliance Notes
This tester is designed to support UL 719 Clause 7.14 abrasion resistance testing of flat cable jackets. Final compliance depends on the complete test procedure, specimen preparation, abrasion tool condition, applied load, reciprocating speed, stroke length, monitoring method and acceptance criteria.
The equipment should be described as a test system for supporting UL 719 flat cable jacket abrasion testing, not as a product certification result. If ISO 17025 calibration documentation is required, the certificate scope and covered parameters should be confirmed before ordering.
