汽车漆面保护膜光泽度测量不确定度评估

Evaluation of uncertainty in gloss test of automobile paint protection film

光泽度是汽车漆面保护膜产品的重要衡量指标。本文依据GB/T 9754-2007和JJF 1059.1-2012标准要求使用光泽度仪对汽车漆面保护膜60°镜面光泽进行了测试,并对不确定度的来源进行了分析,计算得出扩展不确定度为1.54GU。

Gloss is an important measure of automotive paint protection film products. According to the requirements of GB/T 9754-2007 and JJF 1059.1-2012, this paper uses gloss meter to test the 60° mirror gloss of the automotive paint protection film, and analyzes the sources of uncertainty. The uncertainty is 1.54 GU.
