摘要
依据GB/T1040.2-2006《塑料拉伸性能的测定》,测定了聚丙烯塑料的拉伸强度,对拉伸强度测量不确定度进行了分析和量化。当聚丙烯的拉伸强度为26.2MPa时,测量结果的扩展不确定度为0.40MPa。
According to the test method GB/T 1040.2 - 2006 Plastics Determination of Ttensile Properties, tensile strength of the polypropylene was determined. The main sources of uncertainty resulted from the determination process were discussed and calculated. The expanded standard uncertainty of tensile strength determination was 0.40 MPa when the polypropylene tensile strength was 26.2 MPa.
