This standard is published in the D-4945: The number behind the label indicates the age when the standard was first adopted. If it is modified, it refers to the last modified year. 1. Scope 1.1 This test method includes the test procedures for determining the force and velocity response caused by the vertical pile and the inclined pile to the axial impact force of the pile hammer on the pile top. For other deep foundations whose functions are similar to those of pile foundations, regardless of their setting methods, this test method can be used as long as they can accept high-strain impact tests. 1.2 This standard may contain dangerous equipment, operations and equipment. This standard does not indicate all safety issues related to use. The user is responsible for establishing appropriate safety and health measures and determining the applicable rules and regulations prior to use. See note 5 for special notes.
