Footwear - Test methods for uppers, lining and insocks - Seam strength (ISO 17697:2016)

ISO 17697:2016 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 as follows.
-      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 (ISO 17697:2016)

Dieses Dokument legt zwei Prüfverfahren zur Bestimmung der Nahtfestigkeit von Obermaterialien, Futter oder Decksohlen unabhängig vom Werkstoff fest, um die Eignung für den Endgebrauch zu bewerten.
Diese Verfahren sind:
   Verfahren A: Nadelperforationen. Zur Bestimmung der Kraft, die erforderlich ist, um eine Reihe von Nadeln durch einen Werkstoff für Obermaterial in einer Richtung senkrecht zur Nahtreihe zu ziehen.
   Verfahren B: Steppnähte. Zur Bestimmung der Bruchfestigkeit (Reißfestigkeit) von Steppnähten in Schuhobermaterialien und Futterwerkstoffen. Dieses Verfahren ist anwendbar auf, aus Schuhen geschnittene Nähte oder auf Nähte, die zur Nachahmung von Schuhaufbauten zusammengesetzt wurden.

Chaussures - Méthodes d'essai relatives aux tiges, doublures et premières de propreté - Résistance des piqûres (ISO 17697:2016)

ISO 17697:2016 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 qui les compose, afin d'évaluer leur aptitude à l'utilisation finale.
Ces méthodes sont les suivantes:
-      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;
-      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.

Obutev - Preskusne metode za zgornje dele, podloge in vložke - Trdnost šiva (ISO 17697:2016)

Ta evropski standard določa dve preskusni metodi za določanje trdnosti šiva na zgornjih delih, podlogi ali vložkih ne glede na material za namene ocenjevanja primernosti za končno uporabo. Ti dve metodi sta naslednji: Metoda A: perforacije igel. Za določanje sile, ki je potrebna za izvlečenje vrste igel skozi zgornji material v pravokotni smeri glede na vrsto. Metoda B: šivi. Za določanje upogibne trdnosti šivov na zgornjih delih in podlogi obutve. Ta metoda se uporablja za šive, izrezane z obutve ali izdelane za simulacijo konstrukcije obutve.

Overview

EN ISO 17697:2016 (ISO 17697:2016) specifies two standardized test methods to determine the seam strength of footwear uppers, linings and insocks irrespective of material. Its purpose is to assess the suitability of seams and perforation resistance for end use in footwear construction. The European adoption (EN ISO 17697:2016) supersedes EN 13572:2001 and was prepared by CEN/TC 309 in collaboration with ISO/TC 216.

Key topics and technical requirements

• Scope: Tests apply to uppers, lining and insocks, whether cut from shoes or made up to simulate constructions.
• Two methods:
  • Method A - Needle perforations: measures the force required to pull a row of needles through an upper material perpendicular to the row. Key apparatus includes a needle holding jig (17 needles, round point R, metric size 90 / Singer 14), a tensile testing machine and a T‑shaped test specimen. Six specimens are typical (three cut along and three across material direction).
  • Method B - Stitched seams: measures the breaking strength of stitched seams from cut or made-up seams to simulate real footwear construction. Useful tools include a tensile testing machine and, for made-up seams, 50 × 50 mm test specimens and sewing equipment.
• Test equipment and settings:
  • Tensile testing machine with jaw separation rate (100 ± 10) mm/min.
  • Force measurement accuracy greater than 2 % (Class 2 per ISO 7500-1).
  • Typical force ranges: usually < 500 N for upper materials (Method A) and up to 2 kN for stitched seams (Method B).
• Sampling and conditioning: follow ISO 17709 (sampling location/preparation) and ISO 18454 (standard atmospheres for conditioning/testing).

Applications and who uses this standard

• Footwear manufacturers and designers: validate seam constructions and material suitability for end-use durability.
• Quality control and testing laboratories: perform repeatable, accredited seam strength tests for production batches and supplier verification.
• Material and component suppliers: assess and specify performance of uppers, linings and insocks.
• Compliance engineers and spec writers: reference EN ISO 17697 when defining product specifications, test requirements or conformity documentation.

Practical benefits include consistent evaluation of seam performance, improved product reliability, and a common technical basis for supplier contracts and regulatory compliance.

Related standards

• ISO 7500-1 - Verification of static uniaxial testing machines (force measurement accuracy)
• ISO 17709 - Footwear sampling location, preparation and conditioning
• ISO 18454 - Standard atmospheres for conditioning/testing of footwear and components

Keywords: seam strength, footwear testing, EN ISO 17697, needle perforation test, stitched seams, uppers, linings, insocks, tensile testing machine.
