A hardness test is typically performed by pressing a specifically dimensioned and loaded object (indenter) into the surface of the material you are testing. The hardness is determined by measuring the depth of indenter penetration or by measuring the size of the impression left by an indenter.
The Rockwell hardness number is calculated from the depth of permanent deformation of the indenter into the sample, i.e. the difference in indenter position before and after application of the major load. The minor and major loads can be applied using dead weights or springs.
Unless otherwise requested the calibration interval on your durometer will be one year. Several factors should be taken into consideration such as: the required accuracy vs. the instruments accuracy, the impact an out of tolerance reading will have on the process, and the performance history.
PROCEDURE Take out the force gauge to be calibrated and hold vertically up. Adjust the zero on the force gauge. Standard Weights are then applied to the hook of force gauge and measure the tension of the spring on the force gauge. When 1 kg of standard weight is applied, scale on the force gauge should also show 1 kg tension produced from the initial point where the pointer is adjusted. Adjust the zero on the force gauge again. Follow the same procedure for other weights. The test to be carried out for 1.0 kg, 2.0 kg, 5.0 kg, 10.0 kg, 20.0 kg & 30.0 kg standard weights.
