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.

Preferred Test Sample Size

Rock core specimens

Number of Test Specimens

1 or more

Test Specimen Size

Dependent on the actual size of the individual grains of the specimen.
