论述了纤维卷尺的历史溯源和量值溯源。依据JJG52001《纤维卷尺、测绳检定规程》，详细论述了纤维卷尺的不确定度评定的步骤与方法，按照校准方法，数学模型，方差和传播系数，标准不确定度，合成不确定度以及扩展不确定度计算的顺序编写。并将其扩展不确定度与规程规定的最大允许误差作比较，得出此测量方法可行的结论。并提出了高精度玻璃纤维卷尺的发展方向。
This paper discusses the history and traceability of fiber tapes. According to JJG52001 “Fiber Tapes and Measuring Ropesverification regulation”, it contains the step and method of measurement uncertainty and discusses the calibration method, mathematics model, variance transmission coefficient,standard uncertainty, combined standard uncertainty and expended measurement uncertainty in order.Comparing the extended uncertainty with the maximum permissible error, weget the feasible conclusion of this test method. At the end it proposes the development direction of highprecision glass fiber tapes.
