MEASURING AND TESTING EQUIPMENT
HARDNESS AND CONCRETE
STANDARD FOR HARDNESS TEST OF VULCANIZED OR THERMOPLASTIC RUBBER
JIS K 6253, ISO7619, ISO868, ASTM D 2240
When the best of Durometer and workpiece are cohered each other, the indentor changes shape of
workpiece by pressurized force caused by spring of Durometer and workpiece makes force againts this
force. Force amount of indentor is indicated as hardness when this pressurized force and repulsive force
are equivalent. The reason why there are various kinds of Durometer, it is for the purpose of measuring.
