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. Is code for Rockwell hardness test?
ISO 6508-1:2015 specifies the method for Rockwell regular and Rockwell superficial hardness tests (scales and applicable range of application according to Table 1) for metallic materials and is applicable to stationary and portable hardness testing machines.
5. How do you use a manual Rookwell hardness tester?
(1) Wipe the top surface of the screw and the upper and lower end surfaces of the worktable, and place the worktable on the screw table;
(2) Clean the support surface of the specimen and place it on the workbench, rotate the handwheel to slowly raise the workbench and push up the indenter until the small pointer points to the red dot and the big pointer rotates 3 circles vertically upwards;
(3) Rotate the indicator shell to make the long engraved line between C and B align with the big pointer;
(4) Pull the loading handle, apply the main test force, and the large pointer of the indicator rotates counterclockwise;
(5) When the rotation of the indicator needle stops, the unloading handle can be pushed back to remove the main test force;
(6) Reading from the corresponding scale on the indicator;
(7) Turn the handwheel to lower the test piece, then move the test piece, and carry out a new test according to the above steps (2)-(6);
(8) After the test, cover the machine with a dust cover.
