  "heading": "Test procedure",
  "text": "(a) a minimum of four full aerosol dispensers per product shall be conditioned to 20 °C ± 1°C with at least 95% of the dispenser immersed in the water for at least 30 min before each test (if the aerosol is fully immersed, 30 minutes conditioning is sufficient);\n(b) comply with general requirements. Record the temperature and relative humidity of the environment;\n(c) determine the internal pressure at 20°C ± 1 °C (to eliminate faulty or partly filled aerosol dispensers);\n(d) measure the discharge or flow rate of the aerosol product to be examined, so that the amount of test product dispensed can be more accurately gauged;\n(e) weigh one of the aerosol dispensers and note its mass;\n(f) on the basis of the measured discharge or flow rate and following the manufacturer's instructions, release approximately 5 g of the product onto the centre of the clean watch glass with the aim of producing a mound no higher than 25 mm;\n(g) within five seconds of completion of discharge, apply the source of ignition to the edge of the sample at its base and at the same time start the chronometer (stopwatch); if necessary, the ignition source shall be removed from the edge of the sample after approximately two seconds, in order to clearly observe if ignition has occurred; if no ignition of the sample is apparent, the ignition source shall be reapplied to the edge of the sample;\n(h) if ignition occurs note the following points:\n(i) the maximum height of the flame in cm above the base of the watch-glass;\n(ii) the flame duration in s;\n(iii) dry and re-weigh the aerosol dispenser and calculate the mass of the released product;\n(i) ventilate the test area immediately after each test;\n(j) if ignition is not obtained and the released product remains in the form of a foam or paste throughout its period of use, steps (e) to (i) shall be repeated; allow the product to stand for 30 seconds, 1 minute, 2 minutes or 4 minutes before applying the ignition source;\n(k) repeat the test procedure steps (e) to (j) twice more (a total of 3) for the same can;\n(l) repeat the test procedure steps (e) to (k) for another two aerosol cans (3 cans in total) of the same product.",
