Abstract:The evaluation of the uncertainty for the measurement of the plastics flexural strength was introduced. The uncertainties induced by each factors were evaluated. Finally the extend uncertainty of the plastics flexural strength was gotten, it can be expected that sector from (14. 27-0. 38) MPa to (14. 27+0. 38) MPa contained 95% possible value of flexural strength measure result.
Keywords:Flexural strength  Uncertainty  Evaluation
