number. Report the mean as the Aggregate Crushing Value, unless the individual results differ by more than 0.07 times the mean value. In this case repeat the test on two further specimens, calculate the median of the four results to the nearest whole number and report the median as the Aggregate Crushing Value. A data sheet is given as Form 7.7.1.
