摘要
ASTM E8/E8M标准几经修订,已经从ASTM E8/E8M-15修订为目前最新版本ASTM E8/E8M-16ae1,修订内容主要增加了五种非理想状态拉伸试验要求及材料试验机试验速度校验标准做法等。为了评估实验室是否能够满足该标准的变化,对拉伸试验方法的主要变化内容进行了分析,并对现有万能材料试验机及拉伸试验软件进行了探讨。结果表明,实验室能够满足ASTM E8/E8M-16ae1的标准要求,拉伸试验软件仍然有效,并指出了实际操作的注意事项。
ASTM E8/E8M standard has been revised several times,which has been revised from ASTM E8/E8M-15 to the latest version of ASTM E8/E8M-16ae1.The revised contents mainly add five kinds of non ideal state tensile test requirements and material testing machine test speed calibration standard practices.In order to evaluate whether the laboratory can meet the changes in this standard,the main changes in the tensile test method were analyzed.The existing universal material testing machine and tensile testing software were analyzed and discussed.The results show that the laboratory can meet the requirements of the revised ASTM E8/E8M-16ae1,the tensile test software is still valid,and the practical operation precautions are put forward.
