Overview
EN ISO 17709:2018 (adoption of ISO 17709:2004) specifies how to take, prepare and condition samples and test pieces from footwear and footwear components for laboratory testing. The standard defines a reference sampling system, sample shapes and sizes, and the required conditioning before applying test methods used to determine suitability for end use. EN ISO 17709:2018 supersedes EN 13400:2001 and is intended as the general sampling and conditioning reference unless a specific test method states otherwise.
Key topics and requirements
- Sampling location and reference system
- The standard defines a locating axis system (X and Y axes) and a zero point on the shoe to ensure repeatable sampling positions across uppers, outsoles, insoles, linings and components.
- Sample shapes and dimensions
- Test-piece geometries (circular, rectangular, T-shaped, dumb-bell, etc.) and example sizes are provided so samples are compatible with common footwear test fixtures (e.g., circular Ø34 mm discs for upper tests).
- Preparation and orientation
- Instructions cover how to cut samples relative to the X axis (parallel) or Y axis (perpendicular) and how to prepare seamed or composite specimens (shanks, toe puffs, stiffeners treated as whole components).
- Conditioning before testing
- Samples must be conditioned for the duration specified in the standard or in the corresponding test method. Conditioning times are given per test and ensure consistent moisture/temperature state prior to testing.
- Scope and applicability
- Applies to samples taken from finished shoes and individual components to support standardized test methods that evaluate flex resistance, tear strength, delamination, abrasion, water resistance, bondability and many other properties.
Practical applications and users
- Footwear manufacturers and product engineers use EN ISO 17709:2018 to:
- Define sample locations and preparation for in-house quality checks and R&D.
- Ensure compatibility and repeatability when submitting samples to independent test laboratories.
- Test laboratories and certification bodies rely on the standard to:
- Prepare test pieces correctly so results are comparable across labs and compliant with footwear test methods.
- Material and component suppliers reference the standard when delivering materials intended for validated performance testing.
Related standards
EN ISO 17709:2018 is used together with specific footwear test methods. Normative references included in the standard (examples) are:
- EN 13511 (lastability)
- EN 13512 (flex resistance)
- EN 12770 / EN 12771 (outsole abrasion / tear strength)
- EN 1392 (adhesive bondability)
