1. Scope

This standard covers the object, principle, apparatus and test procedures for non-destructive testing of concrete structures using impact-echo technique. This technique is employed for the determination of wave velocity, measurement of thickness of concrete structures, detection of flaws, location of reinforced bars and determination of delamination of reinforced bars. In addition, some additional guidelines for the impact-echo testing and the errors involved in the measurement are also given.
