Abstract：GB/T 228.1-2021 Metallic Materials-Tensile Testing-Part 1: Method of Test at Room Temperature was officially implemented on July 1st, 2022. The main changes between GB/T 228.1-2021 and GB/T 228.1-2010 were compared, and the main differences between GB/T 228.1-2021 and ASTM E8/E8M-21 were summarized. The technical differences of the above standards were compared and analyzed in terms of the scope, nouns and terms, symbols, samples, and size measurement, testing equipment and accuracy, testing requirements and performance measurement, result rounding off and uncertainty in measurement. The results showed that the technical contents of GB/T 228.1-2021 had changed greatly compared with GB/T 228.1-2010, for example, adding two different types of strain rate control modes and the method for measuring the elastic modulus of metal materials by uniaxial tensile test, changing the estimation method of displacement rate of deformation compensation beam of testing machine system, etc. Compared with the above national standards, there were great technical differences between GB/T 228.1-2021 and ASTM E8/E8M-21, so we should be familiar with the relevant provisions during the test. Through the comparison of above standards, it was helpful for standard users to have a deeper understanding and use of relevant standards in actual production, teaching and scientific research.
