THE AMBIENT TEMPERATURE AND QUALITY OF THE HARDNESS MEASUREMENT

Three appraisers carried out the calibration of hardness tester by Vickers and Brinell methods, using on standard (CRM) with defined both values of standard hardness and their uncertainty. The ambient temperature of laboratory varied in range 14.9 to 27.6°C at ten levels. The influence of the temper...
