22、ean Standard describes the method of determining the flammability of an aerosol product sprayed in the form of a foam, mousse, gel or paste. 2 Terms and definitions For the purposes of this document, the following terms and definitions apply. 2.1 ignition appearance of a stable flame which is at lea
23、st 4 cm high and which is maintained for at least 2 s. 3 Principle Approximately 5 g of foam, mousse gel or paste is sprayed from the aerosol container on to a watchglass. An ignition source (candle, wax taper, match or lighter) is placed at the base of the watchglass and any ignition and sustained
24、combustion of the foam, mousse, gel or paste is observed. 4 Apparatus 4.1 Scale for measuring height of flame, graduated in centimetres. 4.2 Support and clamp for holding the graduated scale in position. 4.3 Fire-resistant watchglass, approximately 150 mm in diameter. 4.4 Chronometer (stopwatch), ac
25、curate to 0,2 s. 4.5 Candle, wax taper, match or lighter. 4.6 Calibrated laboratory scales (balance), accurate to 0,1 g. 4.7 Water bath, accurate to 1 C and maintained at 20 C. 4.8 Thermometer, accurate to 1 C. 4.9 Hygrometer, accurate to 5 %. 4.10 Pressure gauge, accurate to 0,1 bar. 5 Preparation
26、of test apparatus 5.1 Place the watchglass on a fire-resistant surface within a draught-free area that can be ventilated after each test. 5.2 Position the graduated scale exactly behind the watchglass so that the origin of the scale is level with the watchglass base in a horizontal plane. 5.3 Restra
27、in the scale vertically in this position by means of the support and clamp. 5.4 Condition a minimum of four full aerosol dispensers per product to 20 C 1 C by immersing at least 95 % of the dispenser in water at this temperature for at least 30 min before each test.

28、May 16 04:07:30 BST 2006, Uncontrolled Copy, (c) BSIEN 14851:2005 (E) 5 6 Test conditions The tests shall be carried out in a draught-free environment capable of ventilation, with the temperature controlled at 20 C 5 C and relative humidity in the range of 30 % to 80 %. 7 Test procedure 7.1 Prime ea
29、ch aerosol dispenser by discharging for approximately 1 s. NOTE The purpose of this action is to remove non-homogeneous material from the diptube. 7.2 Record the temperature and relative humidity of the environment. 7.3 Determine the internal pressure within the aerosol dispenser at 20 C 1 C. If the
30、 internal pressure indicates that the dispenser is likely to be faulty or incompletely filled it shall not be used for the test. 7.4 Measure the discharge rate or flow rate of the aerosol product to be examined, so that the amount of test product dispensed can be more accurately gauged. 7.5 Determin
31、e the total mass of the full aerosol dispenser. 7.6 On the basis of the measured discharge or flow rate, and following the manufacturers instructions, release approximately 5 g of the product onto the centre of the clean watchglass with the aim of producing a mound no higher than 25 mm. Follow stric
32、tly the manufacturers instructions for use, including whether the dispenser is intended to be used in the upright or inverted position. When shaking is required, shake immediately before testing. 7.7 Within 5 s of completion of discharge, apply the source of ignition to the edge of the sample at its
33、 base and at the same time start the chronometer (stopwatch). If necessary, remove the ignition source from the edge of the sample after a few seconds in order to clearly observe if ignition has occurred. If no ignition of the sample is apparent, reapply the ignition source to the edge of the sample
34、. 7.8 If ignition occurs, note the following: maximum height of the flame in centimetres above the base of the watchglass; flame duration in seconds. 7.9 Dry and re-weigh the aerosol dispenser and calculate the mass of the released product. 7.10 Ventilate the test area immediately after each test. 7
35、.11 If ignition does not occur and the released product remains in the form of a foam, paste, mousse or gel throughout the test, repeat steps 7.7 to 7.10. Allow the product to stand for 30 s, 1 min, 2 min and 4 min before applying the ignition source. 7.12 Repeat 7.5 to 7.11 twice more (a total of t
36、hree) for the same can. 7.13 Repeat 7.5 to 7.12 for another two aerosol cans (three cans in total) of the same product. 8 Test report The test report shall include the following information: a) whether the product ignites; b) maximum flame height in centimetres; c) duration of flame in seconds; d) m
37、ass of the product tested.
