insufficient roof surface roughness, e.g. caused by a smooth weather-proofing to the roof;c)inappropriate type of roof surface e.g. the type of roof ballast used;d) surface water, e.g. after rain;e) surface contaminants, e.g. lichen; moss; chemicals;f)icy conditions, e.g. caused by overnight freezing after rain;g)the roof angle and pitch, especially on a downward slope.Figure F.8 — Example of two deadweight anchor devices sharing the loadF.3.3.8 A deadweight anchor should be able to withstand a minimum static load of (15 +1/0) kN for (3 +0,25/0) min when tested in the test house with the base fixed and the load applied to the anchor point in the direction(s) intended in use. The load should be applied gradually, i.e. as slowly as is practicable. During the test, yielding is acceptable but should take into account any necessary clearance distances required to avoid contact by the rope access technician with the ground or structure, should a fall occur.
