Point Load Test

Point Load Test
This is a simple test procedure involving portable equipment. The point load strength is closely correlated with the results of uniaxial compression and other strength test.
The Point Load Strength Index can be calculate from
Is = P/D2
Where    Is = Point Load Strength Index (MPa)
P = Failure load
D = Distance between two platens contact points

The Uniaxial Compression Strength can be calculated from the Point Load Strength Index value multiplied by 24 in the unit of MPa.
