Description
The international hardness test is based on measurement of the penetration of a rigid ball into the rubber specimen. The hardness is obtained by the difference in penetration depth of a specified dimension ball under conditions of contact with a minor force and with a major force. The differential penetration is taken at a specified time and converted to a hardness scale value. It’s performed according to ASTM D 1415, KS M ISO 48 and ISO 48.
The Vluchem’s IRHD-Micro is a full automatic instrument which is far from operator’s influences and rubber material, polymer such as o-ring, oil seal and various molded final goods.
