Foreword
This European Standard (EN ISO 17707:2005) has been prepared by Technical Committee CEN /TC 309
"Footwear", the secretariat of which is held by AENOR, in collaboration with Technical Committee ISO/TC 216
"Footwear".
This European Standard shall be given the status of a national standard, either by publication of an identical text or
by endorsement, at the latest by January 2006, and conflicting national standards shall be withdrawn at the latest
by January 2006.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic, Denmark,
Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta,
Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom.
1 Scope
This European Standard 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, in
accordance with the test mentioned in Clause 6, have a maximum longitudinal rigidity of 30 N.
NOTE The method described in this standard is based on the method for the determination of the flex resistance for
outsoles described in EN ISO 20344.
2 Normative references

3 Terms and definitions
For the purposes of this European Standard, the following term and definition apply.
flex resistance
number of flexes that cause cut growth and/or initiation of cracks in the outsoles
4 Apparatus and material
