Ultrasonic Pulse Velocity Test

Ultrasonic Pulse Velocity tests are performed to assess the condition of structural members with two-sided access such as elevated slabs, beams, and columns. Voids, honeycomb, cracks, delaminations, and other damage in concrete, wood, masonry, stone, ceramics, and metal materials can be identified and mapped with the method. UPV tests are also performed to predict the strength of early age concrete.

The UPV test relies on direct arrival of compressional waves. Sources and receivers used in the tests have resonant frequencies ranging from 50 to 150 kHz. The higher resonant frequency receivers are typically used with thinner structural members for higher resolution and smaller anomaly identification. In the basic UPV test, the first arrival times of the ultrasonic energy are registered by a V-meter. Olson Engineering records the full waveform with a digital oscilloscope card for troubleshooting of material condition.
