Round the result to the nearest whole number, and report the mean of two observations as the Aggregate Impact Value. What do the AIV values mean? Here are the recommended Aggregate Impact Test values and their corresponding classifications: Aggregate Impact Value Classification. Less than 20%: Exceptionally strong. Between 10% and 20%: . Detailed Impact Test on Road Aggregates with calculation of Impact value has been shown, also range of aggregate impact value is explained.Toughness is the p.compressive load. With aggregate of aggregate impact value (AIV) higher than 30 the result may be anomalous. Also aggregate sizes larger than 14 mm are not appropriate to the aggregate impact test. The standard aggregate impact test shall be made on aggregate passing a 14. mm BS test sieve and retained on a 10.0 mm BS test sieve. If required . Pharmacovigilance aggregate reporting is nothing short of revolutionary for patient safety! Aggregate reports and aggregate safety reports not only offer an invaluable way to identify and address any issues with a given drug, but they also offer the opportunity to monitor its long-term effects thoroughly.
