Overview

prEN ISO 10764 (ISO/DIS 10764:2008) is a CEN draft standard that defines a repeatable test method to assess the lateral strength of closed slide fasteners used in footwear. The method is applicable to all types of slide fastener and is intended to support quality control, product development and regulatory compliance by providing standardised measurement of failure load and failure mode.

Key Topics

• Purpose: Assess lateral strength of closed slide fasteners for footwear.
• Test principle: Pull the stringers laterally in a tensile testing machine until failure and record the maximum force.
• Apparatus and accuracy:
  • Tensile testing machine with jaw separation rate of (100 ± 10) mm/min.
  • Force measurement accuracy to class 2 per ISO 7500-1, with capacity ranges for light (0.5 kN), medium (1 kN) and heavy (2 kN) duty fasteners.
  • Two clamps with square ends of (25.5 ± 0.5) mm width, corrugated or abrasive coated surfaces, avoiding localised pressure at the clamping edge.
  • Optional locating jig and, for heavy duty chains, solvent-based polychloroprene adhesive to aid gripping.
• Specimen preparation: Minimum of three test positions (or three fasteners); each test position requires at least 50 mm of free closed fastener on either side of the clamped area. Mark clamping lines (25 ± 2 mm) parallel and 3.0 ± 0.5 mm from the teeth edge.
• Procedure highlights: Close the fastener, clamp each stringer aligned to the marked lines, align chain at 90° to the machine axis, run at the specified jaw rate until failure, and record the maximum force in newtons and the observed failure mode.
• Failure modes recorded: Locked teeth separation, teeth pulled off the stringer, stringer failure, stringer torn at clamp edge, or clamp slip.

Applications

This test method is valuable for:

• Quality control - routine inspection of fastener batches to ensure consistent lateral strength.
• Product development - comparing fastener types (light, medium, heavy duty) and materials during design iterations.
• Supplier qualification and procurement - defining acceptance criteria based on mean maximum forces and failure modes.
• Durability assessment and compliance - providing objective data for footwear performance claims and regulatory documentation.

Related Standards

• ISO 7500-1 - verification of force measuring systems for tensile testing machines.
• ISO 17709 - sampling locations, preparation and conditioning for footwear tests.
• ISO 18454 - standard atmospheres for conditioning and testing of footwear components.
• ISO 19952 - footwear vocabulary (terms and definitions used in this standard).

Test report should include reference to the method, full sample description, test date, arithmetic mean maximum forces, failure types and any deviations from the method. This ensures traceability and practical utility of lateral strength data for footwear manufacturers, test labs and standards officers.
