# The Aerosol Dispensers Regulations 2009, Paragraph 6.3.2.2.2.1


A cylindrical vessel approximately 200 dm3 volume, approximately 600mm in diameter and approximately 720mm long and open at one end shall be modified as follows:
(a) a closure system consisting of a hinged cover shall be matched to the open end of the receptacle; or
(b) a plastic film 0.01 to 0.02 mm thick may be used as a closure system; if the test is carried out with a plastic film this must be used as described below: stretch the film over the open end of the drum and hold it in place with an elastic band; the strength of the band shall be such that when placed around the drum resting on its side, it stretches by only 25mm when a mass of 0.45 kg is attached to its lowest point; cut a 25 mm slit in the film, starting 50 mm from the edge of the drum. Ensure that the film is taut;
(c) at the other end of the drum drill a 50mm diameter hole 100mm from the edge in such a way that the orifice is uppermost when the receptacle is laid down and ready for the test (Figure below);
(d) on a 200 × 200 mm metal support place a paraffin wax candle 20 to 40 mm in diameter and 100 mm high; the candle shall be replaced when having a height of less than 80 mm; the candle's flame is protected from the action of the spray by a 150 mm wide, 200 mm high deflector; this includes the plane inclined at 45° produced 150 mm from the base of the deflector (see Figure below);
(e) the candle placed on the metal support shall be positioned midway between the two ends of the drum (see Figure below);
(f) the drum is laid on the ground or on a support at a spot where the temperature is between 15 °C and 25 °C; the product to be tested will be sprayed within the drum of roughly 200 dm3 in which there will be a source of ignition.
