Footwear - Test methods for outsoles - Flex resistance (ISO 17707:2005)

ISO 17707:2005 specifies a method for determining the flex resistance of outsoles. This method is intended to assess the effect of sole materials and surface patterns on cut growth. This method is applied to outsoles that have a maximum longitudinal rigidity of 30 N.

Schuhe - Prüfverfahren für Laufsohlen - Biegeverhalten (ISO 17707:2005)

Dieser Normentwurf legt ein Verfahren für die Bestimmung des Biegeverhaltens von Laufsohlen fest. Mit diesem Verfahren wird beabsichtigt, die Auswirkung von Sohlenwerkstoffen und Oberflächenmustern auf das Weiterreißen eines Schnittes zu bewerten. Das Verfahren gilt für Laufsohlen, die in Übereinstimmung mit den in Anhang A genannten Prüfungen eine maximale Längssteifigkeit von 30 N haben.

Chaussures - Méthodes d'essai applicables aux semelles d'usure - Résistance a la flexion (ISO 17707:2005)

L'ISO 17707:2005 prescrit une méthode de détermination de la résistance à la flexion des semelles d'usure. Cette méthode vise à évaluer l'influence des matériaux constitutifs de la semelle ainsi que celle du relief de la surface sur l'agrandissement d'une entaille. Elle s'applique aux semelles d'usure qui, conformément à l'essai mentionné dans l'Article 6 ont une rigidité longitudinale maximale de 30 N.

Overview

EN ISO 17707:2005 - Footwear: Test methods for outsoles - Flex resistance (ISO 17707:2005) is a CEN-adopted ISO method for determining the flex resistance of shoe outsoles. The standard measures how sole materials and surface patterns influence cut growth and crack initiation under repeated bending. It applies to outsoles with a maximum longitudinal rigidity of 30 N (measured at 45° flex).

Key topics and technical requirements

• Scope: Method for assessing cut propagation and crack initiation on outsoles with longitudinal rigidity ≤ 30 N.
• Rigidity test: Outsoles are bent to 45° at (100 ± 10) mm/min and the force (0–50 N sensor, ±1 %) is recorded. Outsoles requiring >30 N at 45° are excluded from flex resistance testing.
• Flex resistance apparatus:
  • Mandrel diameter: 30 ± 0.1 mm around which the outsole is flexed.
  • Flexing rate: device capable of 135–150 cycles/min, flexing through 90° ± 2° about the mandrel axis.
  • Cycle counter and firm end clamps to align the flexing line.
• Test pieces & conditioning:
  • Test pieces may be taken from complete footwear or outsole units; attach a standard insole (cellulose board) of 2 ± 0.1 mm thickness and apparent bulk density 0.55 ± 0.05 g/cm³.
  • Condition samples 24 h according to EN 12222 (standard atmospheres).
• Cut initiation and measurement:
  • A single incision is made with a specified chisel; chisel is lubricated with soap and water.
  • Initial cut length L(o) measured in fully flexed position (accuracy 0.1 mm).
  • Subject outsole to 30 000 flexes; re-measure cut length L(f). Report cut growth as L(f) − L(o).
  • Record additional cracks (number and longest length to 0.5 mm).
• Test report must include results, sample identification, test method reference, test date and any deviations.

Applications and users

• Useful for: footwear manufacturers, material suppliers, test laboratories, R&D teams, quality control and compliance engineers.
• Practical uses:
  • Compare outsole compounds and tread patterns for durability against cut growth.
  • Evaluate new outsole formulations or cleat designs during product development.
  • Provide repeatable, standardised data for marketing claims and regulatory compliance for footwear performance.

• EN 12222 - Standard atmospheres for conditioning and testing of footwear.
• EN ISO 534 - Paper and board thickness/density (for insole specification).
