Rubber test – Determination of rebound resilience (Schob pendulum)
The method specified here serves to determine the resilience of rubber having a Shore A or IRHD hardness between 30 and 85 (see DIN 53519-1) when subjected to impact. This method is particularly suitable for a rough evaluation of the dynamic behavior of rubber by simple equipment. When the rubber is deformed, it absorbs energy that is partly recovered when it regains its original shape. Energy that is not returned as mechanical energy dissipates as heat in rubber.
