For the BS 812-112 method, a small portion of 14–10-mm-sized coarse aggregate particles is confined in a steel pot and subjected to 15 blows by a small hammer in a standardised test rig, after which the ‘ aggregate impact value’ (AIV) is determined from the fine material generated, expressed as a percentage of the original weight of the test portion (BS 812-112: 1990).
