BS EN ISO 13934 outlines a precise and standardized testing procedure to evaluate fabric
tensile strength. This consistency is vital to produce reliable data that can be compared
across different labs and products.
Step-by-Step Breakdown of the Strip Method
The strip method involves cutting the fabric into strips of a specified width and length,
then subjecting these strips to tensile force until they break. The key stages include:
Sample Preparation: Fabric specimens are cut into strips, typically 50 mm wide,
1.
although this can vary depending on the fabric type and test requirements.
Conditioning: Samples are conditioned in a controlled environment—usually at
2.
20°C and 65% relative humidity—for at least 24 hours before testing to ensure
consistent moisture content.
Testing: The strip is clamped into a tensile testing machine equipped with
3.
appropriate grips.
Measurement: The machine applies a uniaxial tensile load at a constant rate until
4.
the fabric breaks.
Data Recording: The maximum force applied at the moment of rupture is recorded
5.
as the tensile strength, and elongation at break is also measured.
Equipment and Calibration
Using the correct equipment is essential when performing BS EN ISO 13934 tests. The

Key Features of the BS EN ISO 13934 Testing Method
The testing protocol under BS EN ISO 13934 is characterized by several technical
specifications that ensure accuracy and repeatability:
Strip Method: The fabric is cut into strips of specified dimensions, usually with a
1.
width between 20 mm and 50 mm, to isolate tensile properties in a controlled
manner.
Test Speed: The standard prescribes a constant rate of extension—commonly 100
2.
mm/min—to ensure uniform testing conditions.
Specimen Conditioning: Prior to testing, specimens are conditioned under
3.
standardized temperature and humidity to minimize environmental effects on fabric
behavior.
Data Acquisition: The machine records maximum load (tensile strength) and
4.
elongation at break, providing quantitative metrics for fabric evaluation.
These features collectively enhance the reliability of tensile strength measurements,
enabling meaningful comparisons between different fabrics and suppliers.
Comparisons with Other Textile Strength Testing Standards
While BS EN ISO 13934 is among the most widely used standards for tensile testing, it
exists alongside other standards such as ASTM D5034 (Grab Test) and ASTM D5035 (Strip
Test). Compared to ASTM D5034, which uses a grab method and tends to yield lower
tensile strength values due to the nature of the grip, BS EN ISO 13934’s strip method
