To complicate matters more, for fine and all-in aggregate, where D <= 8mm, the standard requires producers to declare a "typical grading", which, where required, must be within a given Tolerance Category designated according to a set ± value on the D/2 sieve, i.e., G TC 10, G TC 20 or G TC NR (no requirement). A typical quarry dust could be designated 0/4 G A 85 G TC 20.Get Price
