2015年炭黑和白炭黑测试实验室间比对结果分析

Analysis of Interlaboratory Comparison Test Result of Carbon Black and Silica in 2015

介绍2015年炭黑和白炭黑实验室间炭黑着色强度、炭黑氮吸附比表面积和白炭黑氮吸附比表面积测试的比对结果分析。结果表明,炭黑着色强度和白炭黑氮吸附比表面积比对测试均只存在1个离群结果,炭黑氮吸附比表面积比对测试存在2个离群结果,出现离群结果的实验室应进行仪器、试剂和测试条件等的校准和修正,提高测试水平。

The interlaboratory comparison test results of carbon black and silica in 2015 were analyzed. The tests included coloring strength of carbon black,nitrogen adsorption specific surface area of carbon black and silica. The testing results of coloring strength of carbon black and nitrogen adsorption specific surface area of silica showed one outlier result,respectively,and testing results of nitrogen adsorption specific surface area of carbon black showed two outlier results. The laboratories presenting the outlier results needed to improve the testing quality by calibration and correction of instruments,testing reagents and testing parameters.
