Test Method Title
Standard Test Method for Laboratory Determination of Pulse Velocities and Ultrasonic Elastic Constants of Rock
Reference Number
ASTM D2845
Material
Rock
Test Property
LPV and TPV (Longitudinal and transverse pulse velocity)
Description of Test
Pulse velocities of compression waves and shear waves in rock and the determination of ultrasonic elastic constants of an isotropic rock or one exhibiting slight anisotropy are determined with this method. Elastic constants should not be calculated for rocks having significant anisotropy by this method. Waves are propagated at one end of a rock specimen and the speed at which it is received at the opposite end is used to calculate density and ultrasonic elastic constants.
Number of Test Specimens
1 or more
Test Specimen Size
Dependent on the actual size of the individual grains of the specimen.
