Overview
ISO/TS 20358:2024 - Footwear - Performance requirements for components for footwear - Accessories specifies performance requirements and test methods for footwear accessories such as laces and eyelets, metal components, touch-and-close fasteners, zippers and trims. It is intended to assess suitability for end use across all kinds of footwear by classifying products by exposure (Classes A–D) and defining minimum performance thresholds and test procedures. The technical specification is a practical reference for manufacturers, suppliers, test laboratories and quality teams involved in footwear component selection and verification.
Key topics and technical requirements
- Scope and classification
- Accessories for all footwear types are covered and grouped by exposure:
- Class A (slight): e.g., infant shoes, slippers, fashion shoes
- Class B (medium): casual and school shoes, many adult work shoes (non‑PPE)
- Class C (high): sport shoes, trekking/hiking, heavy work (non‑PPE)
- Class D (heavy): heavy‑duty sports and similar high‑stress footwear
- Performance areas and typical limits
- Laces and eyelets - abrasion resistance: Required fatigue/abrasion cycles vary by class and test method (ranges from about 1 000 up to 20 000 cycles depending on exposure and method).
- Metal components - corrosion resistance: Must meet a minimum corrosion grade (no worse than grade 4) per ISO 22775.
- Touch-and-close fasteners (hook & loop): Specified shear strength and peel strength before and after repeated opening/closing cycles (e.g., minimum shear typically in the tens of kPa and peel strength in the 0.06–0.10 N/mm range after cycling; values depend on class).
- Zippers: Requirements for puller attachment strength (e.g., ≥250–300 N), lateral load (e.g., ≥400–500 N), and fatigue resistance (e.g., ≥1 000–2 000 cycles) per ISO 10734, ISO 10764 and EN 16732.
- Trims and attachment strength: Minimum attachment strength requirements (for some classes ≥50 N) evaluated per ISO 24263.
- Marking and labelling: Optional. If used, accessories claiming compliance must be clearly marked with manufacturer identification, intended footwear class, and reference to ISO/TS 20358:2024; markings must not be visible on finished footwear.
Applications - who uses this standard
- Footwear component manufacturers and suppliers for product spec and supplier agreements.
- Footwear OEMs, designers and product development teams to select components appropriate to use-class.
- Quality assurance and compliance teams for incoming inspection, conformance testing and labeling decisions.
- Test laboratories performing the referenced methods to verify accessory performance.
