- Rectangle 150x100x16 mm
- HB 5/125 to 10/3000
- Extra large block for a hardness value from 150 HB
The Brinell hardness test blocks are used for the yearly, indirect verification and calibration of Brinell hardnesster as well as the cyclic (daily) check of the hardness tester.
Buderus Edelstahl hardness test blocks (Made in Germany) are delivered with a DAkkS-Certificate (DIN EN ISO 6506-3) from the Materialprüfungsamt Nordrhein-Westfalen (MPA NRW). For hardness test blocks, certified by the MPA NRW, there is an Excel-Sheet available where the calibration value, limit deviation and tolerable repeatability of the hardness tester as well as the measurement uncertainty of the hardness test block are noted. By means of this sheet a cyclic verification of your hardness test can be documented without any efforts within the framewort of quality assurance.
For the optimum utilization of the hardness test block, a raster can be engraved if requested.
Please Note: Brinell hardness test blocks with a hardness value >150HB can you find here here.
