(iv) has two support frameworks, placed on the opposite side of the burner from the spray container, one at a distance of 15 cm from the burner and the other at a distance of 100 cm from the burner, each of which

(A) has an internal open space for testing a pressurized container of 35 cm wide by 100 cm high or, for testing a pump-spray container, of 35 cm wide by 60 cm high,

(B) is constructed from metal or other non-flammable material,

(C) is mounted in a vertical plane perpendicular to the direction of discharge from the spray container, and

(D) is adjustable in the vertical plane;

(b) a cylinder of chemically pure (C.P.) grade propane fitted with a regulator capable of delivering pressure to the burner appropriate to maintaining a flame height of 5 cm; and

(c) loosely woven cotton fabric commonly referred to as cheesecloth that has, in the bleached state, a mass per unit area of not less than 35 g/m² and not more than 65 g/m².

Test Specimen

3. (1) When there are instructions by the manufacturer respecting the shaking of the spray container, a test composed of the following number of discharges from each of three spray containers of the same product and of the same size must be conducted:

(a) in the case of a pressurized container, three discharges; and

(b) in the case of a pump-spray container, 10 discharges.

(2) When there are no instructions by the manufacturer respecting the shaking of the spray container, a test, using each of three spray containers of the same product and of the same size, must be conducted as follows:

(a) in the case of a pressurized container, without shaking the container, discharge it three times and then, after shaking it in the manner set out in paragraph 4(9)(a), discharge it a further three times; or

(b) in the case of a pump-spray container, without shaking the container, discharge it 10 times and then, after shaking it in the manner set out in paragraph 4(9)(a), discharge it a further 10 times.

Procedure

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 pressure 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 the following trial discharges from the spray container:

(a) in the case of a pressurized container, a single discharge; and

(b) in the case of a pump-spray container, three discharges.

(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,

(iii) 15 seconds after the cessation of shaking, release the first discharge in accordance with subsection (10), and

(iv) allow the spray container to stand for at least 60 seconds between discharges; or

(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 10 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 nozzle position and each of 18 N, 36 N and 54 N of pressure.

(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.

Determination and Reporting of Flame Projection and Flashback

5. (1) If at any time during the test the cheesecloth that is mounted at a distance of 100 cm from the burner is ignited, the length of the flame projection is 100 cm or more.

(2) If at any time during the test the cheesecloth that is mounted at a distance of 15 cm from the burner is ignited and, at all times during the test, the cheesecloth that is mounted at a distance of 100 cm from the burner remains unignited, the length of the flame projection is 15 cm or more but less than 100 cm.

(3) If at any time during the test the cheesecloth mounted at a distance of 15 cm from the burner is not ignited but there is a flame projection, the length of the flame projection is less than 15 cm.

6. The following test results must be recorded:

(a) the length of the flame projection

(i) in the case of a pressurized container, for each discharge, and

(ii) in the case of a pump-spray container, for each discharge at each nozzle position and each pressure applied;

(b) a lack of flame projection resulting from any of the test discharges; and

(c) any flashback.

TEST METHOD FOR DETERMINING WHETHER A CONTAINER LEAKS

Interpretation

Definitions

1. The definitions in this section apply in this Schedule.

"seal" « sceau d'étanchéité »

"seal", in respect of a container, means any device or membrane under the closure that covers the opening of the container, including any membrane that is part of the container, such as a heat induction seal or a sonic seal. It does not include a liner or a mechanism that is an integral part of the closure. (sceau d'étanchéité)

"test sample" « échantillon d'essai »

"test sample" means

(a) in the case of a container of a chemical product, the container filled with the product in the manner in which it is sold to the consumer; or

(b) in the case of an empty container that is destined to receive a chemical product, the container filled with the product that it is destined to receive. (échantillon d'essai)

Test Method

Preparation of Sample for Testing

Remove seal

2. Except in the case of a single-use container,

(a) open the test sample;

(b) remove any seal that is present under the closure in accordance with the manufacturer's instructions or, if no instructions are provided, puncture the seal; and

(c) reclose the sample as tightly as possible without stripping the threads of the closure.

Bring to room temperature

3. Place the test sample in a test location that has a constant temperature of 23 ± 2°C for at least four hours to permit the container and its contents to reach the temperature of the test location.

Testing for Leaks

Position of test sample

4. Position the test sample

(a) over a clean piece of blotting paper or another paper that stains on contact with a liquid;

(b) in an inverted position at a 45° angle below the horizontal; and

(c) with the closure in the lowest possible position and free of any obstruction.

Examine paper

5. After one hour, remove the test sample and examine the paper described in paragraph 4(a) for evidence that any of the contents have leaked from the sample.

Pass or Fail

Fail

6. If an examination of the paper described in paragraph 4(a) discloses any trace of the contents of the test sample, the sample has failed the leakage test and a container of the same type as the test sample must not be used for a chemical product.

Pass

7. If no trace of the contents of the test sample is found on the paper described in paragraph 4(a), the sample has passed the leakage test and a container of the same type as the test sample may be used for a chemical product.
