Application Summary AI generated

This standard specifies a method for determining the torsional stiffness of flexible plastic materials, specifically targeting plasticized compounds of vinyl chloride homopolymers and copolymers. It is applied in quality control and material characterization within the rubber and plastics industry, particularly for assessing the flexibility and low-temperature performance of products like cables, hoses, and films. The test measures how a material resists twisting under controlled conditions, aiding in formulation development and compliance verification.
