ISO 16177:2012 specifies a test method for determining the resistance of a component or material to crack initiation and growth due to repeated flexing. The method is mainly applicable to outsoles of footwear but may also be used with certain other flexible components.

Abstract

Overview

ISO 16177:2012 - "Footwear - Resistance to crack initiation and growth - Belt flex method" specifies a laboratory test method to determine how a component or material resists crack initiation and growth from repeated flexing. The method is primarily intended for footwear outsoles but may be applied to other flexible footwear components. It simulates repeated short-period flexing (as at the toe/forepart) by bonding specimens to a continuous cotton-canvas belt that passes over two rollers.

Key topics and technical requirements

Test principle: Specimens are adhesively bonded to a driven cotton canvas belt which runs over a flexing roller and a driven roller; repeated flexing cycles produce and propagate cracks that are recorded.
Apparatus: flexing machine with specified roller dimensions (examples in the standard: 90 mm centre diameter for typical soles; 120 mm for soles >15 mm; a 225 mm driven roller), continuous cotton canvas belt, heating device, counting method and hand tools.
Belt and speed: belt dimensions and material properties are defined; machine drives the larger roller to give about (90 ± 8) flexing cycles per minute (driven roller speed ~247 ± 20 r/min).
Adhesives & surface prep: a two-stage polyurethane adhesive system (pre-reacted and single‑component PU) plus primers for rubber, EVA or thermoplastics are specified. Surface preparation (scouring, priming, MEK wipe for PVC/PU) is required by material type.
Specimen preparation: details for cutting, marking toe‑heel centre line, thickness limits (reduce >15 mm to 15 mm), and optional mechanical fastening for very stiff specimens.
Inspection and reporting: specimens are inspected at recommended intervals (e.g., 2 500, 5 000, 10 000, 20 000… up to 50 000 cycles). Crack position, length (to nearest 1 mm) and depth class (superficial, shallow, moderate, deep) are recorded. Test report must include reference to ISO 16177:2012, specimen description, roller diameter used, number of cycles, damage observations, test temperature and any deviations.

Applications

Product development and materials selection for outsoles and flexible components.
Quality control and batch verification for manufacturers of footwear and sole compounds.
Comparative testing of outsole formulations, treads and constructions to evaluate durability under repeated flexing.
Research labs studying crack initiation, rubber/EVA performance and bonding methods.

Who uses this standard

Footwear manufacturers and sole compound formulators
R&D and testing laboratories
Quality assurance teams in footwear production
