ISO 20871 is the ISO standard that specifies a method for determining the abrasion resistance of footwear outsoles, whatever the outsole material. The current edition is ISO 20871:2018, which replaced ISO 20871:2001 and was confirmed by ISO in its last review.
Because the method applies regardless of material, footwear makers and their suppliers can use one method to compare different outsole materials. Labs cite it in outsole specifications and supplier approvals, and keep specimen preparation and test conditions consistent so that results from different batches and suppliers can be compared. Before testing, labs confirm the edition and the acceptance values set by the brand or product specification.
Abrasion testers such as our DIN abrasion tester are used for outsole abrasion testing to ISO 20871. If you need help matching ISO 20871 requirements to your parts or setup, contact our team.
