Pile Integrity Testing (PIT) is a Non-Destructive integrity test method for foundation piles. It is a “Low Strain” Method (since it requires the impact of only a small hand-held hammer). The evaluation of PIT records is conducted either according to the Pulse-Echo (or Sonic Echo – a time domain analysis) or the Transient Response (frequency domain analysis) Procedure. This test is standardized by ASTM D5882 Standard Test Method for Low Strain Impact Integrity Testing of Deep Foundations.
