The test measures the energy absorbed during tearing and provides valuable information about fabric durability and resistance to damage. Widely used for woven fabrics and many nonwoven materials, the method supports quality control, product development, material comparison, and compliance testing across textile, industrial, and technical fabric applications.<\/p>\n<h2 data-section-id=\"vy42b5\" data-start=\"1121\" data-end=\"1144\">What Is ISO 13937-1?<\/h2>\n<p data-start=\"1146\" data-end=\"1375\"><strong data-start=\"1146\" data-end=\"1282\">ISO 13937-1: Textiles \u2014 Tear Properties of Fabrics \u2014 Part 1: Determination of Tear Force Using Ballistic Pendulum Method (Elmendorf)<\/strong> specifies a method for measuring the force required to propagate a pre-cut tear in a fabric.<\/p>\n<p data-start=\"1377\" data-end=\"1598\">The standard evaluates the energy needed to continue a tear over a fixed distance after a sudden force is applied.
