and not to have a permanent deflection more than a specified amount A specified force is applied to a step which tries to pull the step out of the unit The step is required to carry the load for without showing any signs of pull out at the end of this period B.3 Apparatus B.3.1 For the vertical loading test The apparatus shall consist of: a) a test block, capable of distributing the load

accuracy of ± % of the applied load; c) a measuring device, suitable for measuring deflection, with an accuracy of ± 0,5 mm B.3.2 For the horizontal pull-out test The apparatus shall consist of: a) a
