A NEW APPROACH TO FORCE TRACEABILITY IN HARDNESS MEASUREMENTS

C. Kuzu, E. Pelit

Abstract

Force traceability in hardness measurements is provided via force measurement devices which are requested to have an accuracy Class 0,5 for hardness calibration machines, an accuracy Class 1 or accuracy of 0.2 % for hardness testing machines according to ISO 376 as indicated in the relevant ISO hardness standards. The most accurate way of having force traceability is to have the force measurement device calibrated against high accurate force standard systems. In this paper investigation and results of providing force traceability of force measurement instruments calibrated against deadweight type hardness standard machines is explained in detail.
