字迹材料耐久性中色差测定不确定度评估及分析

Evaluation and Analysis of Uncertainty in Color Difference Measurement in the Durability of Handwriting Materials

本文介绍了目前字迹材料耐久性常用的评价方法,并根据DA/T 16-1995《档案字迹材料耐久性测试法》中色差的测试方法,对字迹材料色差进行测试,分析评估色差测量过程中不确定度的来源,以进一步提高检测水平,确保测量结果的准确性和可靠性。结果显示,试样重复性引入的不确定度较大,设备引入的不确定度影响较小。

This paper introduces the common evaluation methods for durability of handwriting materials,and measures the color difference of handwriting material according to DA/T 16-1995,Durability testing method for archival handwriting materials.It analyzes and evaluates the source of uncertainty in contact angle measurement to further improve the testing level and ensure the accuracy and reliability of measurement results.The result shows that the uncertainty introduced by repetitive measurement was more than that introduced by equipment.
