Difference Analysis between National and American Standards of Tensile Test Method and Revision Suggestions on the National Standard

The technical differences between ASTM E8/E8M-16a and GB/T 228.1-2010 were analyzed from the aspects of sample size, test equipment, test rate, result representation and revision, the differences between the two standards were summarized, and the revision suggestions for GB/T 228.1-2010 were put forward. The results show that there are great differences between the two standards in specific regulations, and the tester must be familiar with the relevant regulations before the test. Revision suggestions of the key technical problems of GB/T 228.1-2010 tensile test about the symmetry of the parallel length part of the tensile sample and the measurenent method of original and after break cross sectional area were given.
