1. The method to be used for testing the structural integrity of a crib under dynamic conditions is as follows:

• (a) assemble the crib according to the manufacturer’s instructions, omitting accessories that could interfere with the conduct of the test;

• (b) secure the crib to a horizontal surface in the manufacturer’s recommended use position in a manner that will not interfere with the conduct of the test;

• (c) place on the mattress support a 100-mm thick sheet of polyurethane foam that has a density of 30 kg/m³, a 25% indentation force deflection of 144 N and a length and width that meet the requirements of paragraph 20(b) of these Regulations;

• (d) using a 20-kg test load of the dimensions illustrated in Figure 1, allow the test load to fall freely, from a height of 150 mm above the initial position of the upper surface of the sheet of polyurethane foam, 150 times at a rate of one impact per second at the geometric centre of the surface of the sheet, in such a manner that the upper surface of the test load remains parallel to the horizontal surface referred to in paragraph (b);

• (e) record any damage to the crib, any disengagement or permanent deformation of its latching or locking mechanisms and any loosening of its mattress support fasteners;

• (f) without readjusting the mattress support, repeat the procedures set out in paragraphs (d) and (e), except that, at each of the mattress support mechanisms, allow the test load to fall at a point that, when measured from the geometric centre of the test load, is 150 mm from the innermost surfaces of the sides nearest the mattress support being tested, measured at the level of the upper surface of the sheet of polyurethane foam; and

• (g) repeat the procedures set out in paragraphs (d) and (e), except that, at the midpoint along the edge of the mattress support beside each movable side, allow the test load to fall at a point that, when measured from the geometric centre of the test load, is 150 mm from that side measured at the level of the upper surface of the sheet of polyurethane foam.

2. The method to be used for testing the structural integrity of a crib under horizontal force conditions is as follows:

• (a) assemble the crib according to the manufacturer’s instructions, omitting accessories that could interfere with the conduct of the test;

• (b) secure the crib to a horizontal surface in the manufacturer’s recommended use position in a manner that will not interfere with the conduct of the test;

• (c) with any movable sides of the crib in the adjustment position designed to provide accommodation for an unattended child and using a point that is midway along the length of one of the sides, but not more than 50 mm from the upper edge of the side, as the point of contact, apply a horizontal force of 120 N perpendicularly to the side in a back-and-forth motion at a frequency of 150 cycles per minute for a total of 9 000 cycles;

• (d) record any damage to the crib, any disengagement or permanent deformation of its latching or locking mechanisms and any loosening of its mattress support fasteners; and

• (e) repeat the procedures set out in paragraphs (c) and (d) for every other side of the crib.

3. The method to be used for testing the structural integrity of a crib under vertical force conditions is as follows:

• (a) assemble the crib according to the manufacturer’s instructions, omitting accessories that could interfere with the conduct of the test;

• (b) secure the crib to a horizontal surface in the manufacturer’s recommended use position in a manner that will not interfere with the conduct of the test;

• (c) with any movable sides of the crib in the adjustment position designed to provide accommodation for an unattended child and using the midpoint of the top of one of the sides as the point of contact, apply a vertical force of 120 N in an up-and-down motion at a frequency of 150 cycles per minute for a total of 9 000 cycles;

• (d) record any damage to the crib, any disengagement or permanent deformation of its latching or locking mechanisms and any loosening of its mattress support fasteners; and

• (e) repeat the procedures set out in paragraphs (c) and (d) for every other side of the crib.

4. The method to be used for testing the structural integrity of a cradle under dynamic conditions is as follows:

• (a) assemble the cradle according to the manufacturer’s instructions, omitting accessories that could interfere with the conduct of the test;

• (b) secure the cradle to a horizontal surface in the manufacturer’s recommended use position in a manner that will prevent it from rocking or swinging;

• (c) place on the mattress support a 80-mm thick sheet of polyurethane foam that has a density of 30 kg/m³, a 25% indentation force deflection of 144 N and a length and width that meet the requirements of paragraph 20(b) of these Regulations;

• (d) using a 13.7-kg test load that has a square contact area of 929 cm², allow the test load to fall freely, from a height of 150 mm above the initial position of the upper surface of the sheet of polyurethane foam, 500 times at a rate of one impact per second at the geometric centre of the surface of the sheet; and

• (e) record any damage to the cradle, any disengagement or permanent deformation of its latching or locking mechanisms and any loosening of its mattress support fasteners.
