This standard specifies the method for measuring the flex resistance and crack growth performance of vulcanized rubber on a special fatigue testing machine. This standard is applicable to the determination of the crack growth performance of vulcanized rubber after repeated flexing. Therefore, cut the sample in advance, so that the crack grows along the cut.
