Abstract：According to the requirement of national standards General rules for analytical and testing methods of coal (GB/T 483—2007), relevant coal parameter of coal testing should be repeated 3 or 4 times when the 2 times repeated determination could not meet the requirements, although the GB/T 483—2007 mentioned the result processing rules, but after 4 times of determination, when several kinds of group could all meet the requirements, which one to choose to determine the final results was not demonstrated clearly.Through example calculation, the solutions when the range could meet the requirements but the average values were not equal to each other were proposed, new ideas to supply and improve the corresponding technical standard specifications were provided.
