SYSTEMATIC ERROR OF LOADCELL TYPE ROCKWELL HARDNESS TESTING MACHINE ON ROCKWELL SCALE R

Pakkratoke Montree, Tassanai Sanponpute
Abstract:
The Rockwell hardness testing scale R can be test plastic. But dead weights and load cell type of hardness tester give different results. This research focused on study of the machine operation behavior. The experiment results showed that testing cycle of load cell type hardness testing machine cannot performed according to testing condition. It causes hardness value are softer than using dead weight type.
