| 中文摘要: |
| 对钢帘线关键拉伸性能破断力和破断伸长率的测量不确定度做了初步的研究和评定，为钢帘线试验方法的进一步改善提供参考 |
| 英文摘要: |
| According to GB/T 33159—2016，the breaking force and breaking elongation of the steel cord were tested.The uncertainty components that introduced from the factors of tensile test machine force value or displacement，experimenter operation，steel cord material non-uniformity，numerical rounding，original gauge length calibration were evaluated by statistical methods.The uncertainty of breaking force and breaking elongation test of the steel cord were finally determined. |
