ASTM E143 is a standard test method established by ASTM International for measuring the modulus of elasticity in torsion. This standard provides guidelines for determining materials’ torsional properties, specifically the shear modulus or rigidity modulus.

The standard outlines the procedure for performing torsion tests on cylindrical specimens to measure their shear modulus. The shear modulus is a measure of a material’s resistance to shear deformation under torsional forces.

The ASTM E143 test method involves applying torque to a specimen while measuring the resulting angular displacement. The shear modulus is then calculated based on the specimen dimensions and the applied torque.

The standard provides specifications for test setup, specimen preparation, test procedure, and data analysis. It ensures that the torsion test is conducted accurately and consistently across different laboratories and testing facilities.

NextGen GenTor Horizontal Torsion Tester complies with ASTM E143 standard.
