1 The following method is to be used for testing the size of mesh openings on a playpen:
(a) cut a sample of mesh with dimensions of 305 mm × 305 mm;
(b) apply a uniformly distributed force of 0.15 N/mm to two opposite edges of the sample so as to induce a state of uniaxial tension;
(c) attempt to insert the tip of the probe illustrated in the figure to this Schedule through openings in the mesh, without cutting the fibres, using a maximum force of 22 N at 10 randomly located areas in the sample; and
(d) remove the force referred to in paragraph (b) and repeat the step in that paragraph by applying the force to the other two opposite edges of the sample and then repeat the step in paragraph (c).
