— Smith and Lee (1968) compared the data obtained by the standard Bond test and the data from the open grinding cycle, i.e. the first grinding cycle of the standard Bond test. Kapur (1970) came to the conclusion that the estimation of the Bond index can be performed on the basis of data from the first two grinding cycles of the standard Bond test.
