Abstract：This paper discussed the new data statistical method of coal reference material research, problems such as between-bottle standard deviation determination, trending analyzing method in stability evaluation, short-term stability research, definite value uncertainty evaluation of multi-laboratory definite value characterization were analyzed, it was suggested that using the trending analyzing method to do the reference material stability evaluation would be good, moreover, in the research process of reference material, long-term stability evaluation and short-term stability research work should be taken care of.
