The Leeb hardness test is a dynamic or rebound method where the ratio of the rebound velocity to the impact velocity of a tunsten carbide ball or a diamond tipped impact body is used to calculate the Leeb hardness number, L, according to the equation:

L =Rebound velocity
Impact Velocity
x 1000

The hardness number is followed by the symbol HL with one or more suffix characters representing the type of impact device.
