EN ISO 13935-1:2014

• Abstract:

  ISO 13935-1:2014 specifies a procedure to determine the seam maximum force of sewn seams when the force is applied perpendicularly to the seam. ISO 13935-1:2014 specifies the method known as the strip test.; The method is mainly applicable to woven textile fabrics, including fabrics which exhibit stretch characteristics imparted by the presence of an elastomeric fibre, mechanical or chemical treatment . It can be applicable to fabrics produced by other techniques. It is not normally applicable to geotextiles, nonwovens, coated fabrics, textile-glass woven fabrics and fabrics made from carbon fibres or polyolefin tape yarns (see Bibliography).; The sewn fabrics may be obtained from previously sewn articles or may be prepared from fabric samples, as agreed by the parties interested in the results.; This method is applicable to straight seams only and not to curved seams.; The method is restricted to the use of constant rate of extension (CRE) testing machines.

Overview

EN ISO 13935-1:2014 - "Textiles - Seam tensile properties of fabrics and made‑up textile articles - Part 1: Determination of maximum force to seam rupture using the strip method" - defines a standardized procedure to measure the maximum force to seam rupture when a tensile force is applied perpendicular to a sewn seam. Commonly called the strip test, this method is intended mainly for woven fabrics (including those with elastomeric fibres or stretch treatments) and is restricted to straight seams and constant‑rate‑of‑extension (CRE) testing machines.

Key topics and technical requirements

• Test principle: A specimen with a seam centred is pulled perpendicular to the seam at a constant rate until the seam ruptures; the peak force is recorded.
• Scope limitations: Mainly for woven textile fabrics; not normally applicable to geotextiles, nonwovens, coated fabrics, textile‑glass woven fabrics, or fabrics made from carbon fibres or polyolefin tape yarns.
• Specimen preparation & sampling: Seams may be taken from sewn articles or prepared from fabric samples. Avoid selvedges, folded/creased areas; only straight seams are valid.
• CRE testing machine: Requires a constant‑rate‑of‑extension (CRE) machine. Metrological confirmation per ISO 10012, force measurement accuracy class 1 (ISO 7500‑1) with maximum force error ≤ ±1%.
• Rate and recording: Machine capability of 100 mm/min rate of extension (±10%); data acquisition frequency at least 8 samples/second if digital recording is used.
• Conditioning: Test atmosphere and conditioning to follow ISO 139 (standard atmospheres for textiles).
• Test output: Report the maximum force to seam rupture and relevant test conditions, specimen details and apparatus used.

Applications and users

• Quality control: Apparel manufacturers and textile mills use this standard to verify seam strength during production and incoming inspection.
• Product development & R&D: Designers and material engineers compare seam performance of different fabrics, stitch types or elastomeric treatments.
• Conformity testing & procurement: Test laboratories and procurement teams use EN ISO 13935-1:2014 to provide comparable, traceable seam strength data for specifications and contracts.
• Regulatory & accreditation bodies: Ensures testing consistency across labs when assessing seam integrity for safety, durability and warranty claims.

Related standards

• ISO 13935-2 - Grab method for seam rupture (complements Part 1).
• ISO 139 - Standard atmospheres for conditioning and testing textiles.
• ISO 7500-1 / ISO 10012 - Machine verification, force measurement accuracy and measurement management.

Using EN ISO 13935-1:2014 helps ensure reproducible seam tensile data, enabling manufacturers, test houses and specifiers to make informed decisions about garment durability, material selection and production quality.
