摘要: For the traceability of hardness and elasticity measurements with instrumented indenters to SI units, a measuring standard based on silicon bending spring stop limit exists. Besides stiffness spring, point measured force–displacement curve at can be used as an additional calibration for both probing force displacement. In round-robin test six participants seven devices stiffness, deflection were compared. The result agree within ±2.8 %, ±4.2 % ±3.2 respectively.
