Problems in Standard ISO 2019 Edition for Tensile Test of Metallic Materials at Room Temperature and Suggestions for Revision of GB/T 2010 Edition

In order to improve GB/T 228. 1 standard, the disputes existing in the standard ISO 6892-1:2019 for tensile test at room temperature of metallic materials were analyzed, and the revision suggestions of GB/T 228. 1-2010 were put forward. The results show that there are still two problems in ISO 6892-1:2019, which exists in the 2009 and 2016 editions,they are method B is labeled "testing rate based on stress rate" and strain control mode and method A are recommended according to the data obtained from the untrue test conditions. It is suggested to restore method C in GB/T 228. 1-2010 draft, which can not only avoid the shortcoming of poor reproducibility of method B test results, but also overcome the shortcomings of lower measurement results and efficiency as well as a lack of practicability of method A.
