The aggregate impact value is the proportion of the sample that passes a 2.36 mm sieve after the hammer impacts. European Standards will not contain the 10 per cent fines test or the aggregate impact value test although a different impact test the German Schlagversuch test has been included.

The aggregates crushing value test should be performed as per IS code 2386 Part IV. First fill the sample aggregate with one-third of the cylindrical measure in three layers. Each layer should be tamped 25times freely. After filling the sample aggregate weigh and record it as W1. Now fill the aggregate in the mould along with the plunger on top.
