| Abstract: | Under two test conditions, ashes in high temperature coal pitch from 26 domes- tic coking plants are measured. It is shown that by standard deviation and t examination there is no obvious difference between the two methods, their test errors are within the allowable range, which can be mutually replaced in the lab analysis. |
