THE AMBIENT TEMPERATURE AND QUALITY OF THE HARDNESS MEASUREMENT

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...

Zusammenfassung: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 temperature on the results of calibration was evaluated by uncertainty, systematic and random errors whereby last two were determined by Youden plot. [PUBLICATION ABSTRACT]
