6 PROCEDURE
The procedure shall be as follows:
(a) Remove item(s) to be tested from the child restraint.
(b) Test wet or dry as appropriate. For wet test, soak the test piece in warm water at 35°C to 40°C for at least 15 minutes.
(c) For wet test, take one item from the water container and shake off excess water. For wet and dry tests, position the test piece between the upper and the lower plates of the bite clamp such that when a force is applied to the loading point, the teeth close and the effect would resemble a child’s bite. Apply the fabric clamp so as to apply the force to pull the fabric out of the bite clamp. See the setup in Figure 2 and position 1 shown in Figure 3.
(d) Evenly and gradually apply a force F1 (see Figure 2) of 200 ±5 N to the loading point in a direction perpendicular to the upper surface of the top plate, over a period of 5 to 10 s and maintain it for a period of 60 s.
(e) After applying the 200 N loading, evenly and gradually reduce the load to 150 ±5 N to the bite clamp, over a period of 5 s and maintain.
(f) After the load of 150 N has been maintained for at least 20 s, gradually apply a force F2 (see Figure 2) of 100 ±5 N to pull the fabric out of the bite clamp.
(g) Maintain the 150 N and 100 N loads for up to a further 30 s unless the test piece moves through the bite clamp by more than 20 mm.
If the test piece slides through the bite clamp by more than 12 mm then move to
Step (i).
(h) Observe whether a piece of fabric has been stripped from its backing or formed pieces. The part that is stripped or the piece shall be flattened out and the area measured.
(i) Repeat Steps (b) to (h) for positions 2 and 3 in Figure 3.
(j) For wet test, place samples back in the warm water between tests for at least 1 minute.
(k) Repeat Steps (b) to (j) for each type of item.
