Footwear - Test methods for whole shoe - Upper sole adhesion (ISO 17708:2018)

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

Schuhe - Prüfverfahren für den ganzen Schuh - Sohlenhaftung (ISO 17708:2018)

Dieser Norm-Entwurf beschreibt ein Prüfverfahren zur Bestimmung des Trennwiderstandes der Obermaterial-Sohleneinheit von der Laufsohle oder anliegender Schichten von der Laufsohle oder zur Messung der Beständigkeit gegen Abriss des Obermaterials oder der Sohle. Darüber hinaus werden Alterungsbedingungen festgelegt, die für die Fertigungskontrolle eingesetzt werden können.
Er gilt für alle Schuhtypen (geklebte, vulkanisierte, spritzgeformte usw.), bei denen die Bewertung der Sohlenhaftung am Obermaterial benötigt wird und bei denen das Obermaterial durchgehend gearbeitet ist (geschlossener Schuh).
ANMERKUNG   In allen Fällen sollte das Ziel darin bestehen, die Haftfestigkeit unmittelbar an der Kante des Aufbaus zu prüfen. Die Prüfung braucht nicht durchgeführt zu werden, wenn die Haftung durch Schleifen (unter Verwendung von zum Beispiel Nägeln oder Schrauben) oder durch Nähen hergestellt wurde.

Chaussures - Méthodes d'essai applicables à la chaussure entière - Liaison tige semelle (ISO 17708:2018)

Le présent document décrit une méthode d'essai visant à déterminer la résistance au pelage de l'assemblage tige-semelle, la résistance au pelage de couches adjacentes de la semelle d'usure ou la résistance à la déchirure de la tige ou de la semelle. Il définit également les conditions de vieillissement utilisables pour le contrôle de la production.
Le présent document s'applique à tous les types d'articles chaussants (collage, vulcanisation, moulage par injection, etc.) pour lesquels il est nécessaire d'évaluer l'adhérence de la semelle à la tige et dont la tige présente une marge d'assemblage continue (chaussures fermées).
NOTE 1    Dans tous les cas, l'objectif recherché est de vérifier la résistance d'adhérence le plus près possible du bord de l'assemblage.
NOTE 2    L'essai n'a pas lieu d'être lorsque le montage est cloué (en utilisant par exemple des semences ou des vis) ou cousu.

Obutev - Preskusne metode za celoten čevelj - Adhezija zgornjega sloja (ISO 17708:2018)

Ta dokument opisuje preskusno metodo za določanje odpornosti proti ločevanju zgornjega sloja od podplata, ločevanje sosednjih slojev podplata ali raztrganje zgornjega dela ali podplata. Določa tudi pogoje staranja, ki se lahko uporabljajo za nadzor proizvodnje.
Ta dokument se uporablja za vse vrste obutve (cementiranje, vulkanizacija, vbrizgavanje itd.), pri katerih je potrebna ocena prilepljenosti podplata na zgornji del in pri katerih je zgornji del izdelan vzdolžno (zaprti čevelj).
OPOMBA 1 V vseh primerih je cilj preveriti sprijemno trdnost stika na mestu, ki je najbližje robu sklopa. OPOMBA 2 Preskus ni potreben, če je stik izdelan z brušenjem (na primer z žeblji ali vijaki) ali šivanjem.

Overview

EN ISO 17708:2018 - "Footwear - Test methods for whole shoe - Upper sole adhesion" is a CEN-endorsed ISO standard that specifies a laboratory test method to measure the resistance to separation between the upper and outsole of finished footwear. The standard covers the force required to separate the upper from the sole, to delaminate adjacent outsole layers, or to cause tear failure of the upper or sole. It also defines conditioning and ageing options for production control. EN ISO 17708:2018 applies to all closed shoe constructions (cemented, vulcanized, injection‑moulded, etc.) where evaluation of sole adhesion is required, but not to assemblies fastened by grindery (nails/screws) or stitching.

Key topics and technical requirements

• Test objective: Measure bond strength nearest the edge of the assembly (upper–sole interface).
• Applicable constructions: Types a–g (conventional lasting, cemented, injected/vulcanized, strobel, welted, multilayer soles) - specific sample preparation differs by type.
• Sampling & conditioning: Footwear must be conditioned according to ISO 18454 for at least 24 hours; allow 72 hours for freshly glued parts when taken directly from production. Optional ageing processes for production control are defined in Annex A. Minimum two items per model.
• Apparatus & measurement: Sharp cutting device; tensile testing machine meeting ISO 7500-1 (force range 0–600 N, low‑inertia, autographic recording); jaws 25–30 mm wide; measuring device with ±0.5 mm accuracy for test‑piece width.
• Test procedure: Cut and, where required, pre‑separate the upper/sole layers (hot knife). Measure width at five points and compute average. Pull in tensile machine at a separation speed of 100 mm/min (tolerance specified in the standard) while recording force/deformation.
• Results & interpretation: Report force per unit width (upper‑sole adhesion), evaluate and classify the mode of bond failure (adhesive separation, cohesive failure, tear, interlayer delamination) and include conditioning/ageing details.

Applications and who uses it

• Footwear manufacturers - production control, incoming/outgoing inspection, process validation (cementing, moulding, vulcanization).
• Quality assurance and R&D teams - compare adhesives, sole materials, and construction methods; verify durability after ageing.
• Third‑party test laboratories and certification bodies - standardized method for supplier verification and compliance testing.
• Procurement and footwear designers - confirm design choices meet adhesion performance requirements.

Related standards

• ISO 18454 - standard atmospheres for conditioning and testing of footwear
• ISO 7500-1 - calibration and verification of tensile testing machines
• EN 344 - earlier basis for this revision

Keywords: EN ISO 17708:2018, upper‑sole adhesion, footwear test methods, bond strength test, sole adhesion testing, tensile testing machine, footwear conditioning, production control.
