ISO/TC 216/WG 1 - Minimum performance requirements and test methods for components for footwear

This document specifies two test methods for the determination of the flexing durability of whole shoes. The two methods might not give comparable results. NOTE The selected test method depends on agreement between relative parties who use this test method or product standards which reference this test method. These methods are not applicable to the whole shoes with heel height more than 50 mm, or the thickness of flexing area of the soles more than 25 mm, or flexing angle less than 45° according to ISO 17707:2005, Clause 6.

This document provides a method for determining 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 and footwear components, outsole units, heel top pieces (top lifts) and sheet soling materials, excepting PPE footwear (Personal Protective Equipment) and special purpose footwear containing spikes, metal studs or similar.

This document specifies a method for determining the attachment strength of footwear upper straps joined to the sole, hooks, eyelets and trims.

This document specifies a method for the determination of the rubbing resistance of leather and synthetic materials using rubber. The method aims to establish testing conditions that are similar to those of the practical use of footwear subjected to drastic stress, as is the case of hiking or children's footwear, where the upper of one of the shoes is expected to rub with the sole of the other. This method is applicable to all types of leather and synthetic materials intended for shoe uppers.

This document specifies a method for determining the attachment pull-out strength of heel top pieces. This method is applicable to all kind of heels with top pieces.

This document describes a test method for determining the resistance to separation of the upper from the outsole, for separating adjacent layers of the outsole or for causing tear failure of the upper or the sole. It also defines conditions of ageing that can be used for production control. This document is applicable to all types of footwear (cementing, vulcanisation, injection moulding, etc.) where the evaluation of sole adhesion on the upper is needed and where the upper is continuously assembled (closed shoe). NOTE 1 In all cases the objective is to test the bond strength nearest to the edge of the assembly. NOTE 2 The test need not be carried out when the bond has been made by grindery (using, for example, nails or screws) or stitching

ISO 22650:2018 specifies a method for the determination of the heel attachment of footwear. It applies to woman's medium and high heeled footwear. This test method measures three related wear properties: - the rigidity of the shoe backpart during normal walking; - the amount of permanent deformation of the backpart caused by a fairly large force applied to the heel in a backward direction; - the force required to detach the heel.

ISO 18896:2018 specifies a method for assessing the stiffness in the longitudinal direction of steel shanks used for the reinforcement of the waist region of women's shoes and of some men's and children's shoes.

ISO 20866:2018 specifies a test method for the determination of the delamination resistance of insoles, irrespective of the material.

ISO 20876:2018 describes a method for evaluating the ability of an insole, irrespective of the material, to hold stitches, or to take clenched metal fastenings. The method has become accepted as a general quality criterion for insole materials even where attachment is by means of adhesives.

ISO 20872:2018 specifies a method for the determination of the tear strength of outsoles, irrespective of the material, using trouser test pieces.

ISO 20874:2018 specifies a method for the determination of the needle tear strength for outsoles, irrespective of the material.

ISO 20867:2018 specifies a method to determine the ability of an insole component to hold a heel pin and to prevent its head from being pulled through the insole component. The method is applicable to insoles used in the seat of footwear with inside attached heels, and also to seat components where outside heel attachments are used and the heel pin is clenched.

ISO 20875:2018 specifies a method for the determination of the split tear strength and delamination resistance for outsoles.

ISO 20873:2018 specifies a method for determining the linear shrinkage after heating of test specimens prepared from outsoles.

ISO 20871:2018 specifies a method for the determination of the abrasion resistance for outsoles, irrespective of the material.

ISO 20863:2018 specifies a method for the determination of the bondability of heat activated and solvent activated stiffeners and toepuffs to upper and lining materials.

ISO 18454:2018 specifies the general conditioning and testing atmospheres for the evaluation of footwear and footwear component properties. ISO 18454:2018 defines two standard atmospheres for conditioning and testing of footwear and footwear components.

ISO 20870:2017 specifies laboratory procedures which are intended to imitate the effects of naturally occurring reactions. The physical properties of interest are measured before and after the application of the specified treatments. The effect of the ageing procedures on any of the physical properties of the material can be examined.
