This British Standard, a Part of the BS 812 series, describes methods for the determination of the ten per cent fines value (TFV) of aggregates which give a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load.
In this British Standard two procedures are described, one in which the aggregate is tested in a dry condition and the other in which it is tested in a soaked condition.
The methods in this standard are applicable to both weak and strong aggregates passing a 14.0 mm test sieve and retained on a 10.0 mm test sieve.
