ISO/CD 458-2

Plastics — Determination of stiffness in torsion of flexible materials — Part 2: Application to plasticized compounds of homopolymers and copolymers of vinyl chloride

Scope

Application of the general method in ISO 458-1 for the above mentioned plastics according to the special case of the method with an angle of deflection between 55 and 65 . The temperatures according to three characteristic values of the torsion stiffness; 300 MPa, 23 MPa and 4 MPa are to be determined for the material under test.
