Introduction

Standard Framework and Technology Evolution

As the first special technical specification for accessories in the footwear industry, ISO/TS 20358:2024 fills the gap in the systematic performance evaluation of footwear components. The standard integrates the test methods originally scattered in multiple standards such as ISO 22774-22777 to form a unified grading evaluation system.

Analysis of core performance requirements

Accessory type	Key test items	Class AD difference
Lace/eyelet	Abrasion resistance (ISO 22774)	The number of test cycles for Class BD is 2-4 times that of Class A
Metal parts	Corrosion resistance (ISO 22775)	All grade requirements ≥Grade 4 (Salt spray test)
Zipper	Transverse strength (ISO 10764)	Class C/D requirements are 25% higher than Class A

Implementation suggestions

Key points of supply chain management

• Raw material verification: Metal parts need to provide a 72-hour salt spray test report
• Process control: Class D shoelaces need to undergo a 20,000 times abrasion pre-test
• Finished product sampling: Perform temperature and humidity balance treatment
as specified in ISO 17709

Breakthrough in technical difficulties

In the standard The cyclic test requirements of class=instrument>Velcro (maintaining 60kPa shear strength after 5000 opening and closing times) require special attention:

1. Use nylon hook and wool matching structure
2. Add UV stabilizer treatment
3. It is recommended to conduct accelerated aging verification
for each batch
