摘　　要：在新的国家标准条件下结合实验室研制改造的针织物顶破强力测量系统,分析了重复测量、材料强力机示值误差、修约精度及横梁移动速度精度对针织物顶破强力测量结果不确定度的影响,计算了各参数的标准不确定度、合成标准不确定度和扩展不确定度,给出了影响针织物顶破强力测量准确度的主要原因。According to the new standard of country, the influence of repeated test, error of indication of a measuring instrument, corrected precision and beam motion velocity on the uncertainty of bursting strength test results were analysed, combining with the testing system of knitted fabric bursting strength. And also the standard uncertainty, combined standard uncertainty and expanded uncertainty of parameters were calculated. Finally, the main factors influencing on the accuracy of bursting strength test of knitted fabric were advanced.
