AI Overview
ISO 17699 is a standard developed specifically for footwear. It evaluates the breathability of uppers and complete upper assemblies, regardless of the material. It primarily measures two metrics: Water Vapor Permeability (WVP) (mass of moisture passing through per area per hour) and Water Vapor Absorption (WVA) (mass of moisture absorbed).
Core Scope & Methods
- Target Material: Footwear uppers, linings, and complete upper assemblies (leathers, textiles, laminates, and synthetics).
- Method A (Permeability): Measures how much moisture can pass through the fabric. The fabric is clamped over a rigid cylindrical container holding a solid desiccant. A precisely controlled mechanical device rotates a turntable and paddle fan overhead to simulate the movement of a foot while walking, and the weight gain is measured to calculate the transmission rate.
- Method B (Absorption): Measures how much moisture the fabric can trap or absorb within its own structure.
Typical Values for Footwear Fabrics
- Minimum requirements for standard work/outdoor footwear uppers: Typically require a Water Vapor Permeability of at least (or).
- Minimum for standard linings: Typically requires (or).
- High-performance/Athletic gear: Breathable upper constructions often target ranges of to handle heavy perspiration.
Finding Specific Standards & Testing
To view the exact testing temperatures, airflow velocities, and detailed equations, you can purchase the official document directly from the ISO Standard Catalog. For certified third-party testing of your fabric, you can reach out to global testing laboratories like Intertek High-Performance Standards.
