按照测量不确定度评定的基本方法和程序对瓦楞原纸定量测量结果的不确定度进行了评定,不确定度来源主要是取样,其次为质量M的重复性测量和天平校准;瓦楞原纸定量测量结果的扩展不确定度是1g/m2,包含因子为2;为提高定量测量准确度,应定期对定量标准试样取样器进行校准。
The uncertainty of the quantitative measurement results of corrugated base paper was assessed according to the basic methods and procedures for the evaluation of uncertainty of measurement. The sources of uncertainty were mainly sampling, followed by repeated measurement of mass M and balance calibration. The results of quantitative measurement of corrugated base paper The extended uncertainty is 1 g / m2 with an inclusion factor of 2. In order to improve the quantitative measurement accuracy, the quantitative standard sampler should be calibrated regularly.
