The method is applicable to aggregates passing a mm test sieve and retained on a mm test sieve. For other size fractions, a recommended method is described in an appendix to this standard. The method is not suitable for testing aggregates with an aggregate crushing value higher than 30, and in such cases the method for ten per cent fines value described in BS 812111 is applicable.

Testing aggregates. Method for determination of aggregate impact value (AIV) Two procedures are described, one in which the aggregate is tested in a dry condition, and on in which it is tested in a soaked condition. The methods are applicable to aggregates passing at mm test sieve and retained on a mm test sieve.
