標準簡介
Specifies a method for the determination of the hardness of vulcanized rubbers preferably of a hardness range between 30 and 85 IRHD: however, the method may also be used for those rubbers with a hardness between 30 and 95 IRHD. The hardness test consists in measuring the difference between the depths of indentation of the ball into the rubber under a small contact force and a large total force.
