Frequently Asked Questions
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 often should a durometer be calibrated?
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.
