摘要
通过试验研究试样不平度对规定总伸长应力σｔ０．５测定值产生的影响，分析产生测量误差的原因，并给出正确测定管体横向拉伸试验规定总伸长应力σｔ０．５对试样不平度的要求。
The article studies influence to specified elongation stress (σ t 0.5 ) total determined value produce from the specimen flatness through experiment , analyses the cause from measurement tolerance and raises requirement to specimen flatness for correctly determining specified total elongation stress (σ t 0.5 ) for pipe body transverse tensile test.
