摘要
Abstract
How to round the tensile strength test values will directly affect the test results.On the basis of introduction of data rounding rules of national standards (GB),aviation standards (HB) and American Society of Testing Materials standards (ASTM),and by analyzing the difference among the rounding results of the same set of tensile strength original test data according to different standards,the application scope of data rounding method of different standards was giver.The results show that the rounding results had a large difference according to different standards.The tensile strength test data should be rounded according to the rounding rules specified in the corresponding tensile test standards.关键词
