Overview
CEN ISO/TS 20952:2026 - "Footwear - Performance requirements for components for footwear - Uppers" (ISO/TS 20952:2024) - is a technical specification established by CEN that sets clear performance requirements for upper components used in all types of footwear. This standard is applicable regardless of the material used for the upper and is focused solely on the performance and suitability of the upper component, rather than the finished footwear product. It includes detailed criteria and associated test methods for evaluating compliance, providing an essential benchmark for footwear manufacturers and suppliers.
Key Topics
-
Scope of Application
- Covers requirements for uppers in all types of footwear (e.g., casual, fashion, sport, work, and children’s shoes).
- Not limited by material, ensuring versatility for a wide range of manufacturing techniques and designs.
-
Performance Requirements
- Specifies both essential and additional requirements for upper components.
- Classifies footwear into exposure-based categories (Class A: slight; Class B: medium; Class C: high; Class D: heavy), aligning test criteria with end-use conditions.
-
Test Methods
- References established ISO and EN test methods to verify performance properties, such as flex resistance, tear strength, seam and bond strength, water resistance, color fastness, abrasion resistance, and more.
- Requires samples to be prepared in accordance with ISO 17709 for consistent and reliable results.
-
Marking and Labelling
- Provides optional guidance on marking compliant uppers, including manufacturer identity, footwear type, and reference to this standard.
Applications
CEN ISO/TS 20952:2026 is a valuable tool for:
- Quality Assurance: Footwear manufacturers can use this standard to ensure the upper components they purchase or produce consistently meet necessary quality and durability thresholds appropriate to the end-use environment.
- Supplier and Manufacturer Communication: The clear classification and performance benchmarks facilitate robust agreements between footwear component suppliers and manufacturers, streamlining procurement and compliance processes.
- Product Development: Designers and engineers can reference the standard during the selection and testing of upper materials to preemptively satisfy global market requirements, especially when exporting to European and international markets.
- Market Entry and Traceability: Ensures traceability and credibility for upper components used within finished footwear, supporting claims of compliance during audits, certifications, and regulatory assessments.
