7.3.2 Off-the-pole test
The following procedure shall be followed during this test:
(a) Torso modification: for symmetrical devices, attach the test leg (see Figure 1) to either leg stump of the wooden torso. For asymmetrical devices, attach the test leg to the torso’s left leg stump for the left-hand test and to the right leg stump for the right-hand test.
(b) Attach the leg support bracket (see Figure 2) to the standard test pole at a height sufficient to prevent the test torso from striking the floor during the drop test, and at 300 from the pole—torso centreline.
(c) Position the torso initially at a height where the tip of the steel leg is not more than 5 mm (0.20 in) directly above the leg-bearing surface of the steel bracket.
(d) Place the FRE on the pole. Adjust it, in accordance with the manufacturer’s instructions, to fit the pole diameter.
(e) Attach the FRE snap hooks to the D-rings on the torso.
(f) Perform the following steps concurrently to position the torso correctly and adjust the FRE (see Figure 7):
(i) Move the torso away from the pole so that slight tension, sufficient to remove the slack in the connecting hardware, is applied to the FRE. The gap between the pole surface and the torso, which is represented by dimension X (see Figure 7) and measured to the torso where the D-rings are attached, should be 30 ± 1 cm (12 ± 0.4 in) or the minimum distance allowed by the FRE, whichever is greater.
(ii) Position the FRE (not the torso) until the centrelines of both the FRE and the D-rings are at the same elevation.
(iii) Adjust the cross-strap’s distance (if applicable) from the pole surface to the manufacturer’s recommended distance for climbing.
(iv) If the FRE is either semi-automatic or automatic, hold it in a “climbing” position in accordance with the manufacturer’s instructions.
(g) Move the torso towards the pole until the tip of the leg is directly above the steel bracket. The FRE will become slack during this step and will fall down at the back of the pole, or, if applicable, may “hang” by the release cords.
(h) Lower the torso until the tip of the leg contacts the bracket, then lower the torso by an additional 5 mm (0.20 in). During this procedure, the torso will tilt back slightly from the pole surface.
(I) Mark the position of the FRE on the back of the pole.
(j) Verify and record that the FRE is adjusted in accordance with Items (a) to (i).
(k) Release the torso. During the test, the leg will slide outwards off the bracket and the torso will fall off the vertical in the opposite direction.
(l) Measure and the record the total FRE slippage on the back of the pole.CSA Z259.14-12 pdf download.
