【摘要】 GB/T228-2002版已于2002年7月1日实施,该标准等效采用ISO6892:1998金属材料室温拉伸试验。力学性能项目的符号和内容发生了变化,对不同规格材料试样类型作出了规定、对部分力学性能项目测量方法及其对应测试结果的评价做出了提示。更多还原

【Abstract】 Standard GB/T228 -2002 which has been implemented on July 1, 2002, is e-quivalent to Standard ISO 6892:1998 metallic materials-tensile testing at ambient temperature. Symbols and content of mechanical property have changed. Different types of material samples are specified. And measurement methods on mechanical property items and their testing results evaluation are also presented.更多还原
