摘要: 针对业内同行在金属材料拉伸试验过程中, 对如何正确理解、执行GB/T 228.1-2010试验方法存在不同看法的现状, 《理化检验-物理分册》编辑部组织业内专家和技术人员就不同的观点分多期进行了阐述和论证, 并联合宝钢等21家实验室于2014年4-6月进行了一次不同控制方式的拉伸比对验证试验。笔者结合该次比对验证试验结果和相关讨论情况, 以及自身的实践和认识, 提出了几点建议, 以供下次本版标准修订时参考。Abstract: Aiming at the situation of existing different views on how to correctly understand and execute GB/T 228.1-2010 during tensile test of metallic materials, the journal of Physical Testing and Chemical Analysis Part A: Physical Testing had organized many times of special report discussions on some issues of GB/T 228.1-2010 and one time of round robin tests of different tensile test control modes in 2014 participated in by 21 labs cooperating with Baosteel. Based on these discussions and round robin tests as well as self recognition and practice, some proposals on next revision of GB/T 228.1 were submitted.
