ASTM D2256 - Standard Test Method for Tensile Properties of Yarns by the Single-Strand Method
ASTM D2256 is a testing standard that specifies the method for determining the tensile properties of monofilament, multifilament, and spun yarns. It provides a testing procedure for determining maximum force and elongation and provides directions for calculating other properties such as breaking tenacity and modulus. ASTM D2256 is intended to determine the quality of the raw material while aiding in quality control of the finished product.
Materials Testing System
Due to its high data capture rate, we recommend our high tier WDW-E Series test frame as the optimal solution for ASTM D2256 testing, although our more affordable WDS Series is also appropriate. A single column frame is adequate for most single-strand yarn specimens as the loads rarely exceed 5 kN. In cases where yarn specimens require greater force, a dual column system may be needed.
