1.1 This test method covers the determination of the pulse velocity of propagation of compressional waves in concrete. This test method does not apply to the propagation of other vibrations within the concrete.

1.2 The pulse velocity is independent of the dimensions of the body provided reflected waves from boundaries do not complicate the determination of the arrival time of the directly transmitted pulse.

1.3 The pulse velocity V is related to the physical properties of a solid by the equation:

where:

The relationship is independent of the frequency of the vibrations.

1.4 The values stated in SI units are to be regarded as the standard.

1.5 This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
