ISO 13934-1 is an international test method for measuring the tensile performance of textile fabrics using the strip method, reporting maximum force and elongation at maximum force.
It is widely used in textile product development and quality control when a consistent, standards-based tensile result is needed for fabric comparisons, supplier qualification, or lot release.

Textiles — Tensile properties of fabrics — Part 1: Determination of maximum force and elongation at maximum force using the strip method
ISO 13934-1 specifies a laboratory procedure to determine (1) the maximum force a fabric sustains in a tensile test and (2) the elongation at the point of maximum force, using a strip specimen configuration.
The method is designed around constant-rate-of-extension (CRE) tensile testing equipment and can be run on specimens conditioned in the standard atmosphere for testing, and on specimens tested in the wet state.
Quick Definition
Document type: Test method (procedure) for tensile testing of textile fabrics using the strip method.
Primary outputs: Maximum force and elongation at maximum force.
Machine class: Constant-rate-of-extension (CRE) tensile testing machine (universal testing machine configured for CRE control).
What This Standard Covers
ISO 13934-1 covers tensile testing of textile fabrics using strip specimens to determine maximum force and elongation at maximum force.
The method is mainly applicable to woven textile fabrics (including some fabrics with stretch characteristics due to elastomeric fibre content or mechanical/chemical treatments). It may also be applicable to fabrics produced by other techniques, but it is not normally used for certain technical or special fabric categories (for example geotextiles, nonwovens, coated fabrics, textile-glass woven fabrics, and selected high-modulus or tape-yarn constructions).
Why This Standard Matters in Testing
Fabric tensile results are often used as a core mechanical benchmark to compare constructions, screen process changes, and support compliance claims in purchasing specifications. ISO 13934-1 provides a recognized strip-method approach so results can be compared more consistently between labs and across production lots.
Because the method is restricted to CRE testing machines, equipment selection and controller capability (force measurement and extension measurement/reporting) are central to producing usable, defensible data.
Common Materials, Product Types, or Applications Covered
ISO 13934-1 is commonly referenced for tensile characterization of apparel and industrial woven fabrics, including constructions that exhibit stretch behavior.
Common use cases: Incoming inspection, supplier qualification, comparative R&D testing of fabric constructions/finishes, and routine QA/QC tensile monitoring where a strip method is required.
Common Test or Verification Workflow
Most ISO 13934-1 programs follow a straightforward tensile workflow, with the exact details (specimen preparation, conditioning, wet-state handling, number of specimens, and reporting format) driven by the referenced edition and any product specification that cites it.
Typical workflow: Condition specimens as required (standard atmosphere and/or wet state) → mount strip specimen in suitable grips → run a CRE tensile test to maximum force → report maximum force and elongation at maximum force per the standard’s reporting rules.
Equipment Commonly Used for This Standard
ISO 13934-1 is typically performed on a universal testing machine configured for CRE tensile testing, with grips and data acquisition appropriate for textile fabrics.
Common equipment: CRE universal testing machine, appropriate fabric grips (to reduce slippage and jaw breaks), force transducer sized for expected loads, and test software capable of capturing maximum force and extension/elongation at maximum force.
Practical equipment caution: For textile fabrics, grip selection and alignment can strongly influence whether breaks occur in the gauge area and whether elongation data is stable; configuration is often as important as load capacity when you are matching a system to a cited ISO 13934-1 requirement.
If you are selecting a CRE system, grips, and load range for ISO 13934-1 tensile work, you can request a detailed quote based on your fabric types, expected force range, and throughput needs.
How to Read This Designation or Revision
ISO 13934-1 identifies the standard number, and Part 1 indicates the strip method within the ISO 13934 series for fabric tensile properties.
When a year is included (for example, ISO 13934-1:2013), it identifies the published edition being cited. Test setup, calculation, and reporting requirements can depend on the exact cited edition, so purchase specifications and reports should match the customer’s referenced year.
Related Standards, Methods, or Frameworks
In the ISO fabric tensile series, ISO 13934-1 (strip method) is commonly paired with ISO 13934-2 (grab method) when a specification allows or requires a different specimen loading approach.
For sewn products, seam-focused tensile standards (for example, the ISO 13935 series) may be cited alongside fabric tensile requirements to separate fabric strength from seam performance.
