Introduction 6.3.1.1.1. This test standard describes the method to determine the ignition distance of an aerosol spray in order to assess the associated flame risk. The aerosol is sprayed in the direction of an ignition source at intervals of 15 cm to observe if ignition and sustained of the spray takes place. sustained combustion is defined stable flame is maintained for seconds. The ignition source gas burner with a blue, non-luminous 4-5 cm in height. 6.3.1.1.2. This test is applicable to aerosol with a spray distance of 15 Aerosol products with a spray than 15 cm such as dispensing mousses, gels and pastes or metering valve, are excluded Aerosol products that dispense mousses, gels or pastes are subject under the aerosol foam flammability 6.3.1.2. Apparatus and material 6.3.1.2.1. The following apparatus is required: Water bath maintained at 20°C accurate Calibrated laboratory scales (balance) accurate Chronometer (stopwatch) accurate Graduated scale, support and clamp graduations Gas burner with support and clamp Thermometer accurate Hygrometer accurate Pressure gauge accurate 6.3.1.3. Procedure 6.3.1.3.1. General requirements 6.3.1.3.1.1. Before testing, dispenser shall and then primed for approximately The purpose of this remove non-homogeneous material from the 6.3.1.3.1.2.

The test shall be draught-free capable of ventilation, temperature controlled ± 5°C and relative humidity in the range 30-80. 6.3.1.3.1.4. Each aerosol dispenser is to be tested:

(a) when full according to the complete procedure, with the gas burner in the range of 15-90 cm distance from the actuator of the aerosol can;

(b) when 10-12% full nominal (% by mass) only one test, either at 15 cm distance from the actuator when the spray from a full can did not ignite at all, or at the flame ignition distance of the spray of a full can plus 15 cm. 6.3.1.3.1.5. During the test, the can shall be positioned as indicated by label instructions. The ignition source shall be positioned accordingly. 6.3.1.3.1.6. The following procedure requires testing the spray at intervals of 15 cm between the burner flame and the aerosol actuator, in the range of 15-90 cm. It is efficient to start at 60 cm distance between burner flame and aerosol actuator. The distance between burner flame and aerosol actuator shall be increased by 15 cm in the case of an ignition of the spray at 60 cm distance. The distance shall be decreased by 15 cm in the case of no ignition at 60 cm distance between burner flame and aerosol actuator. The aim of the procedure is to determine the maximum distance between aerosol actuator and burner flame that leads to sustained combustion of the spray or to determine that ignition could not be obtained at 15 cm distance between the burner flame and the aerosol’s actuator. 6.3.1.3.2.
