Guided by the American standard ASTM D 5882-07, it is technically named "Low Voltage Impact Integrity Test for Deep Foundations" and its main objective is to ensure that the dimensions designed in the project (length and cross-sectional area) are present.

Guided by NBR 6489 (2019), this test method consists of applying static axial compression forces to the plate and recording the corresponding displacements. The test is carried out up to the maximum displacement established by the designer.
