An Automatic Single Yarn Strength Tester is a precision instrument designed to determine the breaking force (strength) and elongation at break of single strands of yarn, including cotton, wool, hemp, synthetic fibers, and core-spun yarns. Operating on the Constant-Rate-of-Extension (CRE) principle, it automates testing for high efficiency and accuracy, complying with key international standards like ASTM D2256, ISO 2062, and GB/T 14344.
