The single-end breaking force and elongation at break of yarns from packages may be determined using the test procedures specified by ISO 2062. The testing of yarn is an essential part between the raw material and manufacturing of fabrics. This process determines the quality of the raw material and aides in controlling the quality of the end product. The test specimen is supported by clamping a test piece in the stationary jaws. A yarn specimen is extended until rupture at a constant rate of displacement and the breaking force and elongation at break are recorded.
