If you are looking for a standard test method for high-strain dynamic testing of deep foundations, you may be interested in downloading the Astm D4945 89 Pdf document. This document, published by the American Society for Testing and Materials (ASTM), describes the procedure for applying an axial impact force with a pile driving hammer or a large drop weight that will cause a relatively high strain at the top of an individual vertical or inclined deep foundation unit, and for measuring the subsequent force and velocity response of that deep foundation unit. High-strain dynamic testing applies to any deep foundation unit, also referred to herein as a pile, which functions in a manner similar to a driven pile or a cast-in-place pile regardless of the method of installation, and which conforms with the requirements of this test method.
