ISO 24267-2020 pdf free.Footwear — Determination of coefficient of friction for footwear andsole components — Test method.
This document provides a method for determining the coefficient of friction between footwear andfloorings under conditions simulating those experienced in the phases of a typical walking step whenslip is most likely to occur.
The method is applicable to all types of footwear and footwear components,outsole units,heel toppieces (top lifts) and sheet soling materials,excepting PPE footwear (Personal Protective Equipment)and special purpose footwear containing spikes, metal studs or similar.
The following documents are referred to in the text in such a way that some or all of their contentconstitutes requirements of this document.For dated references,only the edition cited applies. Forundated references, the latest edition of the referenced document(including any amendments) applies.ISO 13287:2019, Personal protective equipment — Footwear —Test method for slip resistance.
For the purposes of this document, the terms and definitions given in ISo 13287:2019 apply.
The footwear item and underfoot surface are brought into contact, subjected to a specified verticalforce for a short period of static contact then moved horizontally relative to one another at a constantspeed. The horizontal frictional force is measured at a given time after movement starts and thedynamic coefficient of friction is calculated for the particular conditions of the test.
Use apparatus and materials in ISO 13287:2019,Clause 4.
NOTE Regarding standard shoemaking last in ISO 13287:2019,4.1.1, other lasts with the same dimensionsof STM603LTM1) lasts can also be used.
Additional materials/accessories to test samples according to 8.1 to 8.6:
Cellulosic insole material of around 2 mm in thickness for testing soles which are going to be usedin the footwear with an insole (for testing according to 8.2 to 8.6).Two samples shall be tested, right foot and left foot whenever possible, with the exception of top pieceswhere 2 test pieces shall be tested and sheet material where 2 test pieces shall be tested per direction.ISO 24267 pdf download.
