Rockwell Hardness Test Block with DAkkS Certificate
Quadratic 60x60x16 mm
Hardness value from 20 to 65 HRC
The Rockwell hardness test blocks are used for the yearly, indirect verification and calibration of Rockwell hardness tester 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 6508-3) 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.
