煤炭实验室存查煤样的结果评定

Results evaluation on pack checking coal sample of coal laboratory

介绍了协同试验的方法提要,从分样的制备和化验、试验结果及其统计分析程序、方差及复查允许差目标值的计算、统计结果、试验结果总结等方面探讨了试验及统计过程,根据GB/T19494.3中制样和化验总方差的构成理论和相应的协同实验结果,提出了例行试验煤样测定结果评定方法和同一实验室及不同实验室的核验允许差。

The method of synergy test was introduced.The experiment and statistical process were discussed from aspects such as sample preparation and test,test results and statistical analysis procedures,calculation of variance and check of target value of tolerance,statistic results and test results.According to sample preparation,total variance composition theory in GB/T 19494.3and synergistic experimental results,this paper proposed evaluation method of determination results of routine testing samples and tolerance of tests for both in one laboratory and in different laboratories.
