The Shoelace Abrasion Tester is designed to evaluate the wear resistance of shoelaces and eyelets by simulating the friction and tension experienced during actual footwear use. The instrument provides objective durability data, including the number of cycles to failure, enabling quality control, R&D, and performance verification of footwear lacing systems.
Applications
The tester is suitable for evaluating the abrasion resistance of shoelaces and eyelets in:
(1) Athletic shoes: Running shoes, basketball shoes, football shoes.
(2) Casual shoes: Sneakers, loafers, canvas shoes.
(3) Work and safety footwear: Industrial boots, steel-toe shoes with reinforced eyelets.
(4) Children’s footwear: School shoes and sports shoes with frequent lacing.
(5) Leather footwear: Dress shoes with leather laces and metal eyelets.
(6) Outdoor footwear: Hiking boots, trekking shoes, and waterproof boots.
(7) Footwear R&D: Testing innovative shoelace materials, coatings, or eyelet designs.
Standards
(1) SATRA TM93 — Footwear: Shoelace and Eyelet Abrasion Test
(2) DIN 4843 — German Standard for Footwear Component Abrasion
(3) QB/T 2226 — Chinese Standard for Shoelace and Eyelet Durability
(4) SATRA TM154 — Footwear Lacing System Durability Testing
(5) ISO 22774 — Textiles and Plastics – Shoelace Abrasion Testing
(6) EN ISO 20344 — Personal Protective Equipment — Footwear — Test Methods
(7) ASTM F2023 — Standard Test Method for Footwear Components
