In this paper,by studying and sorting out the testing standards of SBS modified bituminous sheet materials,the tensile test is carried out in strict accordance with the inspection and testing requirements,and 15 sets of tensile(longitudinal)test results are obtained through the test.By analyzing the components that affect the uncertainty in measurement,obtain the result of synthetic standard uncertainty of tension used class A and B measurement uncertainties,according to JJF 1059.1-2012《Evaluation and Expression of Uncertainty in Measurement》.The evaluation of uncertainty in tension measurement has guiding significance for the rigor of daily inspection and detection and the judgment of critical value.
