Abstract

This research work has been focused on estimation of the measurement uncertainty for different steel reinforcement bars. The investigated material was HRB400 steel reinforcement with approximately diameter 16 mm and length 500 mm by using uniaxial tensile testing device. International standard ISO 6892: 2016 and guide for measurement uncertainty have been implemented an accurate method to determine the measurement uncertainty of HRB400 steel reinforcement bar measurements. The results of expanded uncertainty for 569.47 N/mm-2 correspond to 0.76 N/mm-2, which fulfil the international standard requirements. This accurate method can be used in most of the accredited laboratories as inspection services of steel reinforcement bar by using uniaxial tensile testing device at good accuracy.
