Homogeneity Evaluation on Rebar Tensile Test Samples Used for Proficiency Testing

In order to ensure the effective implementation of proficiency testing, the provider must provide the homogeneity evaluation of samples. The method for evaluating homogeneity of samples was introduced in detail, and the analysis process for homogeneity evaluation was also introduced with rebar tensile test samples. For the statistical analysis was a complicated process, the statistical software Minitab was introduced to simplify the analysis process, and operation process of the software was also introduced. The results show that the proficiency testing samples was homogeneous and could be provided to the participants of the proficiency testing.
