Example of an Energy Calibration Report on a Standard Penetration Test (ASTM Standard D 1586–67) Drill Rig



This note provides an example of an energy calibration report on standard penetration test equipment. This calibration was designed to determine a standard hammer drop height that would produce 2100 in.·lb (237 N·m) of compression wave energy entering the drill rods as a result of the average hammer blow when using drop procedures as ordinarily used for the rig under calibration.
