Footwear - Test methods for uppers, lining and insocks - Seam strength

This European Standard specifies two test methods for determining the seam strength of uppers, lining or insocks, irrespective of the material, in order to assess the suitability for the end use.
These methods are :
Method A : Needle perforations. For determining the force required to pull a row of needles through an upper material, in a direction perpendicular to the row.
Method B : Stitched seams. For determining the breaking strength of stitched seams in shoe upper and lining materials. This method is applicable to seams cut from shoes or made up to simulate footwear constructions.

Schuhe - Prüfverfahren für Obermaterialien, Futter und Decksohlen - Nahtfestigkeit

Diese Europäische Norm legt zwei Prüfverfahren zur Bestimmung der Nahtfestigkeit von Obermaterialien,
Futter oder Decksohlen unabhängig vom Werkstoff fest, um die Gebrauchseigenschaften im fertigen Zustand
zu bestimmen.
Diese Verfahren sind:
- Verfahren A: Nadelperforationen. Zur Bestimmung der Kraft, die erforderlich ist, eine Reihe von Nadeln
durch einen Werkstoff für Obermaterial in einer Richtung senkrecht durch die Nahtreihe zu ziehen.
- Verfahren B: Steppnähte. Zur Bestimmung der Bruchfestigkeit von Steppnähten in Schuhoberteilen und
Futterwerkstoffen. Das Verfahren ist auf von Schuhen geschnittene Nähte oder Nähte anwendbar, die zur
Nachahmung von Schuhaufbauten zusammengesetzt wurden.

Chaussures - Méthodes d'essai relatives aux tiges, doublures et premières de propreté - Résistances des piqûres

La présente Norme européenne spécifie deux méthodes d'essai permettant de déterminer la résistance des piqûres de la tige, de la doublure ou de la première de propreté, quel que soit le matériau, afin d'évaluer l'aptitude à l'usage prévu.
Ces méthodes sont les suivantes :
¾ méthode A : perforations à l'aiguille. Cette méthode permet de déterminer la force requise pour traverser le matériau de la tige avec une rangée d'aiguilles dans le sens perpendiculaire ;
¾ méthode B : piqûres. Cette méthode permet de déterminer la résistance à la rupture des piqûres dans la tige et dans les matériaux de la doublure. Elle s'applique à des piqûres prélevées sur des chaussures ou à des piqûres réalisées pour simuler la fabrication de chaussures.
