China Leather Reciprocation Abrasion Testing Machine ULB-F14 from Reliable Suppliers and Factory
Application
Operation Process
- Setup Place two square test samples on a standard abrasive surface.
- Testing Apply a constant force to move the samples in a reciprocating motion.
- Dust Control Activate the air extraction system to remove dust, preventing measurement errors.
- Abrasive Flow Ensure the abrasive agent flows beneath the samples for even contact.
- Results Calculate the average thickness reduction rate per thousand cycles, excluding the last ~1.0 mm of the sample.

Frequently Asked Questions
What is the primary function of the Leather Reciprocation Abrasion Tester?
The machine is specifically designed to assess the abrasion resistance of sole leather materials by simulating reciprocating wear under controlled pressure and abrasive contact.
Which international standards does the ULB-F14 model comply with?
This tester fully complies with the IS 6721-2023 ANNEX B standard, ensuring testing protocols meet global footwear quality standards.
Why is the air extraction system critical during the test?
The air extraction system controls dust build-up. By removing leather particles and debris during the reciprocating motion, it prevents measurement errors and ensures consistent abrasive contact.
What are the specimen size and rubbing stroke requirements?
The standard sample size is a 25 mm ± 0.5 mm square. The tester operates with a fixed rubbing stroke of 216 mm at a speed of 30 ± 5 times per minute.
How is the final abrasion resistance calculated?
The results are determined by calculating the average thickness reduction rate per thousand cycles. Note that the calculation excludes the final ~1.0 mm of the sample thickness to maintain data accuracy.
What accessories are standard with the ULB-F14 machine?
The standard package includes 2 pieces of steel plates and 1 power line, allowing users to set up and begin standard testing quickly.
