Overview
EN ISO 22774:2004 - "Footwear - Test methods for accessories: shoe laces - Abrasion resistance (ISO 22774:2004)" is a CEN-adopted ISO standard that defines laboratory test methods to measure the abrasion resistance of shoelaces under repeated rubbing. The standard specifies three distinct test configurations: lace-to-lace, lace-to-standard eyelet, and lace-to-eyelet (from footwear). Results are reported as the arithmetic mean of cycles to failure for six test specimens.
Key Topics and requirements
- Three test methods
- Method 1: lace-to-lace abrasion
- Method 2: lace-to-standard eyelet abrasion (uses a specified brass eyelet)
- Method 3: lace-to-eyelet abrasion using eyelets cut from actual footwear
- Test geometry and motion
- Reciprocating motion: 35 mm ± 2 mm travel, simple harmonic motion
- Frequency: 60 cycles/min ± 6 cycles/min
- Fixed bending angle at contact via spacer/template: 52.5° ± 5.0°
- Tension and loading
- Applied tension of 2.45 N ± 0.03 N (commonly achieved with a 250 g ± 3 g mass over a pulley)
- Test specimens and sample size
- Six test specimens per method (cut lengths specified: typically 300–500 mm depending on method)
- If fewer test stations are available, tests are repeated until six specimens are completed
- Apparatus and fixtures
- Moveable and stationary clamps, spacer, metal strip for mounting carriers, standard eyelets (brass, internal diameter 4.5 mm, length 5.5 mm)
- Conditioning
- Store and test in standard atmosphere per EN 12222 for at least 48 h
- Results and reporting
- Record number of cycles to failure, type of failure, any damage to carriers
- Test report must reference EN ISO 22774, identify method used, describe materials, give arithmetic mean and range, and note deviations or incidents
Applications
- Quality control and acceptance testing for shoelaces and lace assemblies
- Product development and material comparison (coverings, cores, eyelet compatibility)
- Supplier evaluation and procurement specifications for footwear accessories
- Laboratory test protocols for third‑party testing and certification
- Failure analysis where lace wear and durability affect product performance or safety
Who uses this standard
- Footwear manufacturers and accessory suppliers
- Component and materials R&D teams
- Accredited test laboratories and QA departments
- Procurement and compliance officers specifying accessory durability
