Shoelace Abrasion Tester / SATRA TM93 / QB/T2226
Standards
SATRA TM93、DIN-4843、QB/T2226、SATRA TM154
Principle
Let shoelace cross the eyelet clamped on the fiber board, make the shoelace and eyelet form into 90 degree, make the fiber board and shoelace form into 45 degree. Then straining reciprocated the shoelace under the standard tension by eyelet. While the shoelace is damaged, stop the testing.
Product Advantages
Measures Key Durability of Lacing System: Evaluates the wear resistance of both shoelaces and eyelets, critical for footwear performance and lifespan.
Standard Compliant: Designed to meet standards like SATRA TM93. ensuring recognized and comparable test results.
Quantitative Result: Provides objective data, typically the number of cycles to failure.
Controllable Test Parameters: Allows for precise setting and control of tension, stroke length, and test speed.
Multiple Testing Stations: Equipped with multiple positions (6) for simultaneous testing, increasing efficiency.
Simulates Realistic Abrasion: The setup and reciprocating motion simulate the rubbing action that occurs during footwear use.
Versatile Application: Suitable for testing various types of shoelaces and eyelets.
Product Features
Multiple test positions or stations (6 positions) for simultaneous testing of multiple shoelace-eyelet pairs.
Mechanism to securely clamp a standard eyelet mounted on a fiberboard.
System to position the shoelace and eyelet at specified angles (90 degrees and 45 degrees).
Tensioning system that applies a standard load to the shoelace using weights (455g ± 5g per position, 6 weights included).
Mechanism to reciprocate the shoelace back and forth through the eyelet with a controlled movable stroke (76 ± 2 mm).
Controllable test speed (100 ± 5 cpm) for the reciprocating motion.
Touch-screen control interface for setting test parameters and monitoring the test.
Integrated digital counter (0-999.999 range) to track the number of abrasion cycles performed.
Designed to utilize standard eyelets (Brass, Inner diameter: 4.5mm) and fiberboard (25$times$25mm, Inner diameter 5.0 ± 0.2mm).
Robust construction suitable for repetitive abrasion testing.
Application
This shoelace abrasion tester is used for shoelace against standard eyelet abrasion testing, or eyelet against standard shoelace abrasion testing. This tester is suitable for all kinds of shoelace and eyelet.
