This type of test is a measure of the force required to remove a nail. The standard way of going about this test is to use a 6-penny nail driven through a board at right angles to the face. Then the load required to remove the nail in pounds or kilograms is determined. A similar test measures the force necessary to pull a nailhead through the board. A similar 6-penny nail is driven through the board and then pulled by the shank and the force is measured upon pulling the nailhead completely through the board.
