适用范围：This International Standard specifies a method for the determination of the fatigue crack growth rate ofvulcanized rubber under repeated loading over an extended period of time. The crack starts from the tip of acut made in the test piece before the test, and grows progressively until it finally becomes large enough forcomplete fracture to occur. Using a pure-shear test piece, measurements are made to monitor the crackgrowth under the cyclic loading in order to obtain the crack growth rate, i.e. the increase in crack length percycle. Tests are carried out at various tearing energies by varying the strain energy density in the test piece.This is done by changing the strain amplitude.
