BS EN 131-2 Place the ladder laterally, with the longitudinal axis of the ladder in the horizontal position. The lower stile is to be fixed to the support so that the stile ends overhang the supporting surface (see Figure 13). If the rungs/steps are bolted, riveted, or similarly fixed to the stile the edge of the support shall be in line with the bottom lower edge of the assembling hole. If the rungs/steps are fixed to the stile without the stile being penetrated the edge of the support shall be in line with the lower edge of the rung/step.
If a stabilizer bar is permanently fixed to the ladder the bottom stile end test does not apply. A rigid load block 50 mm wide is placed with its end up to and parallel with the end of the stile. The load block shall rest on the stile and shall effect the whole width of the stile. The lateral deflection f of the stile end is measured at the outer edge of the load block in the longitudinal axis.
To be able to obtain a good rest against the stile it is permitted to cut off a part of a sli resistant material, if any.A vertical force F of 1 100 N (see Figure 13 and 14) is placed in the middle of the load block and is maintained for one min. The permanent deflection after removal of the test load together with any damages are noted.The test is repeated on the lower stile without turning the ladder.Requirement: The permanent deflection fin each test shall not exceed 2 mm.Neither fracture nor visible cracks are allowed.This test shall also be performed on supporting legs.
A pre-load F of 200 N shall be applied for the duration of one minute. The position of the rung/steplatform after removal of the pre-load is the origin for measurement.In the position of use of the ladder a test load F of 2600 N (see Figure 15) shall be applied vertically on the midpoint of the weakest rung or step of any design evenly distributed over a width of 100 mm and a depth equal to the rung/step and for the duration of one min.BS EN 131-2 pdf download.
