.
> Tensile standard samples are mainly used for calibration and tensile testing of room temperature tensile testing machines for metal materials. Comparison of machines, quantitative evaluation of tensile testing machine application software, determination of measurement uncertainty of used equipment, periodic verification of laboratory, assessment of test operators and evaluation of test methods.
Features:

It can avoid the shortcomings of the direct calibration method that cannot accurately evaluate the measurement accuracy of the entire tensile testing machine

It can comprehensively calibrate It can check the measurement characteristics of the entire tensile testing machine

and be able to evaluate the uncertainty of the testing machine.
