Calibrated Test Blocks and Serialized Penetrator
- No facility with a hardness tester in use should be without a calibration kit
- Come with calibrated test blocks and the serialized penetrator that was used to inspect each of the blocks in the set
- When a discrepancy is detected in a tester, these kits allow you to determine the direction to proceed to resolve the issue
- Block is serialized, with a certificate detailing the environmental conditions used to test the block
- Blocks are manufactured from square steel or brass plates, as opposed to the more common round bar stock
- The use of plate gives a more accurate and consistent surface for inspection
- Metallurgical tests have proved that during the production of round bar stock, suspended carbides in the mix migrate to the center of the rod
- Blocks are designed to be used only on one side and the indents should be more than 0.01 in from the centers of two indents or no closer to the block's edge than 0.04 in
- Blocks can be used to test rockwell, Brinell or Vickers scales
