LEEB HARDNESS STANDARD WITH LASER MEASURING

Shi Wei, Zeng Wu, Li Qingzhong
  • Abstract:
    The paper describes the principle, structure and performance of a Leeb Hardness Standard with Laser Measuring (HLSlaser). The range of the standard is (200 ~ 900) HL. At the same time, uncertainty of the standard has been evaluated, of which relative expanded uncertainties (k = 2) are at range of 1.0% ~ 1.2%. It has been done to make comparison of HL values tested by the standard and by six HL testers made by EQUOTIP Company of Switzerland with 6 HL blocks manufactured by the same company.
