Reibung - Prüfverfahren für Schuhe für den täglichen Gebrauch und Schuhbestandteile (ISO 24267:2020)
Dieses Dokument stellt ein Verfahren zur Bestimmung des Koeffizienten der Reibung zwischen Schuhen und Bodenbelägen zur Verfügung unter Nachbildung der Bedingungen, die in den Phasen eines typischen Gehschritts wahrgenommen werden, in denen das Auftreten von Rutschen am wahrscheinlichsten ist.
Das Verfahren ist anwendbar für alle Arten von Schuhen und Schuhbestandteilen, Laufsohleneinheiten, Absatzflecken (Deckflecken) und Werkstoffe für Sohlenplatten, mit Ausnahme von PSA Schuhen (Persönliche Schutzausrüstung) und für Schuhe für besondere Zwecke mit Spikes, Metallbolzen oder gleichwertig.
Chaussures - Détermination du coefficient de frottement pour les chaussures et éléments de semelle - Méthode d'essai (ISO 24267:2020)
Le présent document fournit une méthode pour déterminer le coefficient de frottement entre la chaussure et les revêtements de sol dans des conditions simulant celles des différentes phases typiques d'un pas lorsqu'un risque de glissade est très probable.
La présente méthode s'applique à tous les types de chaussures et composants de chaussure, de semelles d'usure, de bonbouts et de matériaux de feuilles de semelle, à l'exception des chaussures d'équipement de protection individuelle (EPI) et des chaussures destinées à un usage particulier comprenant des pics, crampons ou éléments similaires

Friction — Test methods for casual footwear and
components
1 Scope
This method determines the coefficient of friction between footwear and floorings under conditions
simulating those experienced in the phases of a typical walking step when slip is most likely to occur.
The method is applicable to all types of footwear, excepting professional footwear (EPI), outsole units,
heel top pieces (top lifts) and sheet soling materials.
2 Principle
The footwear item and underfoot surface are brought into contact, subjected to a specified vertical
force for a short period of static contact then moved horizontally relative to one another at a constant
speed. The horizontal frictional force is measured at a given time after movement starts and the
dynamic coefficient of friction is calculated `for the particular conditions of the test.
3 Normative references
The following documents are referred to in the text in such a way that some or all of their content

4 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
4.1
normal force
force applied to the surface through the footwear, perpendicular (90°) to the surface. The force includes
the weight of the footwear, shoemaking last (4.1.1 or 4.1.2) or mechanical foot (4.1.3) and mounting
4.2
frictional force
force parallel to the surface and against the direction of movement arising when footwear slides over
a surface
4.3
coefficient of friction CoF
ratio of the frictional force divided by the normal force
4.4
static contact time
time between initial contact of the footwear with the surface achieving a normal force of 50 N and the
beginning of movement
4.5
measurement period
time interval during which the frictional force measurement is taken and during which the test
conditions are satisfied

5 Apparatus and materials
Use apparatus and materials referred to in ISO 13287:2019, Chapter 4, with the following exceptions:
1)
• Regarding standard shoemaking last, other lasts with the same dimensions of "STM603L lasts "
can also be used.
• Regarding test flooring surface, preferably use pressed ceramic tile, or the flooring called up in the
relevant performance requirements. Suitable surfaces include EUROTILE 2 referred to in Annex B
of ISO 13287:2019, other quarry tiles, vinyl, carpet or wood.
Additional materials/accessories needed to test samples according to 7.1 to 7.6:
• Cellulosic insole material of around 2 mm in thickness for testing soles which are going to be used
in the footwear with an insole (for testing according to 7.1).
• Means to secure the soles to the last, as mechanical means, double sided adhesive tape, seal,
adhesives, bands, etc. (for testing according to 7.1).
• Saw and/or sanding machine, for sample preparation (for testing according to 7.3).
• Mechanical systems to attach to the equipment spigot small-sized top-pieces, bigger top pieces,
Slider 96 test piece or other testing samples to the testing machine, that can be used to replace the
shoemaking lasts or mechanical foots (for testing according to 7.5).
• High-hardness rubber material of at least 50 mm × 50 mm (thickness of ≤ 2 mm), for small- sized top
piece testing (for testing according to 7.5).
• Metallic plate made of e. g. aluminium, of at least (180 × 80) mm and 2,5 mm thick, for sheet material
testing (for testing according to 7.6).
6 Sampling and conditioning
6.1 Sampling
Two samples shall be tested, right foot and left foot whenever possible, with the exception of top pieces
where 2 test pieces shall be tested and sheet material where 2 test pieces shall be tested per direction.
6.2 Conditioning
The test items shall be conditioned prior to the test at (23 ± 2) °C and (50 ± 5) %
