Consumer Chemicals and Containers Regulations, 2001 — 4
4 (1) A test (a) must be conducted at a room temperature of 22 ± 2°C in the absence of air currents, with an allowance made for a clearance of 50 cm beyond the support framework that is set at a distance of 100 cm from the burner; and (b) may be conducted in a fume hood with the exhaust fan turned off and the protecting door lowered. (2) Any fume must be removed from the test area and any residue cleaned up after each discharge. (3) Before testing, each spray container must be (a) maintained at a temperature of 22 ± 2°C for at least four hours; and (b) primed by (i) in the case of a pressurized container, discharging the container for five seconds, and (ii) in the case of a pump-spray container, activating the trigger or pump using each of 18 N, 36 N and 54 N of force for each possible nozzle position until (A) in the case of the “stream” position, a continuous stream is produced, and (B) in the case of the “spray” position, a mist is produced. (4) Install the first spray container in the holding device and ensure that the burner orifice is 15 cm from the discharge orifice of the spray container in the horizontal plane and 5 cm below it in the vertical plane and that the discharge orifice points in the direction of the burner. (5) Adjust the burner to give a flame height of 5 cm and release a single trial discharge from the spray container. (6) If the operation set out in subsection (5) does not produce a flame projection, lower the burner orifice by 5 cm and adjust the burner to give a flame height of 12 cm. (7) Attach the cheesecloth to the flammability tester with bulldog clips or in any other manner so as to cover the entire internal space of the support framework set at a distance of 15 cm from the burner and verify that the cheesecloth is at a proper horizontal distance from the vertical plane of the burner orifice on the opposite side of the burner from the spray container. (8) Adjust the height of the support framework so that the cheesecloth will intercept the line of flame projection. (9) Prepare the spray container in accordance with the manufacturer’s instructions and (a) if shaking is applicable, (i) shake vigorously for five seconds, or for the period specified in the manufacturer’s instructions, (ii) install the spray container in the holding device, and (iii) 15 seconds after the cessation of shaking, release the discharge in accordance with subsection (10); or (iv) [Repealed, SOR/2009-165, s. 20] (b) if shaking is not applicable, install the spray container in the holding device and release the discharge in accordance with subsection (10), allowing the spray container to stand for at least 60 seconds between discharges. (10) Discharge the spray container (a) in the case of a pressurized container, for five seconds or until the cheesecloth ignites; or (b) in the case of a pump-spray container, for three sprays or until the cheesecloth ignites. (11) In the case of a pump-spray container, repeat the procedure set out in paragraph (10)(b) for each of 18 N, 36 N and 54 N of force for each possible nozzle position. (12) If the cheesecloth attached to the support framework that is set at a distance of 15 cm from the burner ignites, the remaining discharges referred to in section 3 must be carried out in accordance with subsections (1) to (11) using a new piece of cheesecloth attached to the support framework that is set at a distance of 100 cm from the burner.
