In the EN ISO 13935-1 standard developed by the International Standards Organization (ISO), a test method is defined to determine the maximum strength of the seams when the force is applied perpendicular to the seam. This standard describes a test method known as the strip test. This method is mainly applied to woven textile fabrics, including fabrics that exhibit stretch properties provided by the presence of an elastomeric fiber, mechanical or chemical treatment. This test method can also be applied to fabrics produced with other techniques. The EN ISO 13935-1 standard does not normally apply to geotextiles, non-woven fabrics, coated fabrics, textile-glass woven fabrics and fabrics made from carbon fiber or polyolefin tape yarns.
This test method applies only to straight seams, not curved seams. The method is also limited to the use of constant propagation velocity testing machines.
In fact, the ISO 13935 standard consists of two parts under the main title "Textiles - Sewing properties of fabrics and ready-made textile products":
For the purposes of the EN ISO 13935-1 standard , the strip test refers to a tensile test in which the entire width of the test specimen is held in the jaws of the testing machine. A constant spread rate testing machine is a tensile testing machine equipped with a fixed clamp and another clamp that moves at a constant speed throughout the test. The entire testing system is almost completely free of deflection. The maximum force for seam rupture is the maximum force recorded for a seam perpendicular to the elongation direction during a tensile test under certain conditions, resulting in seam rupture.
Among the numerous test, measurement, analysis and evaluation studies it has given to businesses in various sectors, our organization, with its trained and expert staff and advanced technological equipment, provides maximum strength against seam breakage by using the strip method in fabrics and ready-made textile products within the scope of EN ISO 13935-1 standard. It also provides testing services for the determination of
