An effective test method is to install one ground anchor element into the ground at the F.2.4.9 recommended backward leaning angle (see F.2.4.11) and then apply a load at the intended point of attachment for the anchor line in the intended direction of use. The load should be applied gradually, i.e. as slowly as is practicable. Record the peak load (up to a maximum of 15 kN for 3 min) at which it is pulled from the inserted angle to become vertical, or at which any part of a ground anchor breaks or fails in another way before reaching a vertical position. Then, divide that peak load into the minimum static strength required, which is 15 kN per single user. This gives an approximate number of ground anchor elements needed to be installed. As a precaution, at least one more ground anchor element should be added to the group.
