'''Dynamic load testing''' (or '''dynamic loading''') is a method to assess a [[Deep foundation|pile]]'s [[bearing capacity]] by applying a dynamic load to the pile head (a falling mass) while recording acceleration and strain on the pile head. Dynamic load testing is a ''[[high strain dynamic testing|high strain dynamic test]]'' which iscan be applied ''after ''pile installation for concrete piles.

The procedure is standardized by ASTM D4945-00 Standard Test Method for High Strain Dynamic Testing of Piles. It may be performed on all piles, regardless of their installation method. In addition to bearing capacity, Dynamic Load Testing gives information on resistance distribution (shaft resistance and end bearing) and evaluates the shape and integrity of the foundation element.
