Overview
ISO 10750:2015 - "Footwear - Test method for slide fasteners - Attachment strength of end stops" specifies laboratory test methods to determine the attachment strength of the top and bottom stops of slide fasteners (zippers) used in footwear. The standard is applicable to all types of slide fasteners for shoes and describes three test methods, required apparatus, specimen conditioning and the information to include in a test report.
Key topics and technical requirements
- Scope: Measures force required to pull top or bottom end stops off a slide fastener used in footwear.
- Three test methods:
- Method 1 (Top stop): Closed fastener; slider clamped to upper jaw via a small hook through the puller, stringer/tape clamped in lower jaw; jaws separate to pull top stops off.
- Method 2 (Bottom stop - Slider‑stringer): Open fastener with slider at bottom stop; hook on slider in upper jaw and both free stringer ends clamped together in lower jaw.
- Method 3 (Bottom stop - Stringer‑stringer): Open fastener; each free stringer end clamped separately in the two jaws; jaws separate to pull bottom stop off.
- Apparatus:
- Tensile testing machine with jaw separation rate (100 ± 10) mm/min.
- Force measurement capability up to 1 kN, accuracy ±2% (Class 2 per ISO 7500-1).
- Recording facility for maximum force or force vs. displacement.
- Small hook attachment (recommended wire diameter 1.6 ± 0.2 mm) to engage the slider puller when required.
- Specimens & conditioning:
- Three fasteners per test.
- Condition specimens for 24 hours in accordance with ISO 18454 standard atmospheres before testing.
- Results & reporting:
- Record maximum force (N) and failure mode (e.g., end stop pulled off, puller detached/broken).
- Report the arithmetic mean of three maximum forces and note any deviations from the method.
Applications and who uses it
- Footwear manufacturers and component suppliers for quality control of zippers and fasteners.
- Product development and R&D teams validating end stop designs and materials.
- Independent testing laboratories performing compliance or acceptance testing.
- Procurement and QA professionals specifying performance requirements for slide fasteners in shoes, boots and other footwear.
