…Based on the technical paper by Amir, “Single-Tube Ultrasonic Testing of Pile Integrity,” which was published in the proceedings of the ASCE 2002 Deep Foundation Congress, the following definitions are intended to make a clear distinction between the results of the integrity tests, the physical condition of the pile and the necessary action, if any. The terms were incorporated in the ASTM D6760 standard, for testing large deep pile foundations, based on the crosshole sonic logging (CSL) method. The terms can also be visualized using a Venn diagram (above) in which they can be depicted and distinguished.
