The correct evaluation of accuracy of standard analytic determination process using certified reference coal samples
ZHANG Tai-ping
Abstract：The statistical model of determination result deviation was introduced in this paper, according to the principle of mathematical statistics and the corresponding standard, combining with practical samples and from aspects such as evaluation method introduction, precision evaluation and accuracy evaluation, the evaluation of accuracy of standard analytic determination process using several certified reference coal samples of different levels in the laboratory was demonstrated.It was also indicated that the precision of standard method, authentication value of certified reference coal samples and uncertain information should be utilized adequately.
