水泥凝结时间自动测定仪检测结果的评价分析

Assessment and Analysis of Cement Setting Time Automatic Determination Instrument Test Results

根据水泥凝结时间现行国家标准标准中的规定,通过比对使用水泥凝结时间自动测定仪和标准方法的检测结果,采用允许误差比较、F检验和t检验等方法,验证两种测试方法是否存在显著差异,并利用能力验证结果进行评价分析自动测定仪能是否得出与标准中规定方法相同结果,同时结合实际使用经验提出自动测定仪使用注意事项。

According to the provisions of the current national standards for cement setting time,by comparing the test results of the automatic cement setting time tester and the standard method,and adopting the methods of permissible error comparison,F-test and t-test,whether there is a significant difference between the two test methods was verified.The evaluation analysis utilizes proficiency testing outcomes to determine if the automatic determination instrument can produce results in line with the prescribed standard methods.Furthermore,drawing on practical usage insights,recommendations for the prudent utilization of the automatic determination instrument are put forth.
