1. How do you perform a hardness test?
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.
2. How do I find my Rockwell hardness number?
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.
3. How ofen should a durometer be calibrated?
one year
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.
4. How do you calibrate a digital hardness tester?
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.
