  • Page 12: Leeb Hardness Measurement Process

    EQUIPMENT DESCRIPTION AND MEASUREMENT PROCESS 3.2 Leeb hardness measurement process The measurement process employed here exploits the difference between the impact and rebound speed of a small impact body. This is fired in the impact device onto the sample surface with an exactly defined energy. The plastic deformation on generating the impression on the sample surface requires energy.

    Note: The hardness of the comparison block is indicated on the block. Hardness comparison blocks with DKD certificate are available in three different hardnesses. When the measured values of the dynaROCK II deviates from the hardness of the comparison block, the device must be calibrated. 5.2.1 Operational startup •...

  • Page 19: Mounting The Impact Device

    IMPLEMENTATION OF A MEASUREMENT 5.2.3 Mounting the impact device Press the placement ring of the impact device firmly and without wobbling onto the test specimen. The impact direction must correspond to the set-adjusted direction. 5.2.4 Measuring Press release button above on the impact device. Sample and impact device must be held steady and stable in this case.

  • Page 20: Operation Of The Device

    IMPLEMENTATION OF A MEASUREMENT The measurement is completed with the acoustic signal. If the Leeb hardness is to be converted into another hardness scale, a benchmark comparison test must be carried out in order to obtain a suitable conversion factor for the corresponding material. Test measurements are carried out on the same sample with a well calibrated Leeb hardness testing device, and with another hardness tester, according to the required hardness scale.
