ASTM D1646

ASTM D1646 covers the test methods for measuring Mooney Viscosity, Mooney Stress Relaxation, and Mooney Scorch. Mooney Viscosity and Stress Relaxation are typically run on the polymer giving some insight into the polymer viscosity and elasticity. Mooney Scorch is run on the compounded rubber providing information on the initial rate of cure and the amount of scorch safety time.
