Council Directive of 20 May 1975 on the approximation of the laws of the Member States relating to aerosol dispensers (75/324/EEC) (c. 324)

ANNEX U.K.

6. TESTS U.K.

[F1 6.3. Tests on the flammability of aerosols U.K.

6.3.2. Enclosed space ignition test U.K.

6.3.2.3. Procedure U.K.

6.3.2.3.1. General requirements U.K.

6.3.2.3.1.1. Before testing, each aerosol dispenser shall be conditioned and then primed by discharging for approximately 1 second. The purpose of this action is to remove non-homogeneous material from the diptube. U.K.

6.3.2.3.1.2. The instructions of use shall be strictly followed, including whether the dispenser is intended to be used in the upright or inverted position. When shaking is required, shake immediately before testing. U.K.

6.3.2.3.1.3. 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 30-80 %. U.K.

6.3.2.3.2. Test procedure U.K.

(a) A minimum of 3 full aerosol dispensers per product shall be conditioned to 20 °C ± 1 °C in a water bath with at least 95 % of the dispenser immersed in the water for at least 30 min (if the aerosol is fully immersed, 30 min conditioning is sufficient); U.K.

(b) Measure or calculate the actual volume of the drum in dm ³ ; U.K.

(c) Comply with general requirements. Record the temperature and relative humidity of the environment; U.K.

(d) Determine the internal pressure and initial discharge rate at 20 °C ± 1 °C (to eliminate faulty or partly filled aerosol dispensers); U.K.

(e) Weigh one of the aerosol dispensers and note its mass; U.K.

(f) Light the candle and apply the closure system (cover or plastic film); U.K.

(g) Place the aerosol dispenser actuator orifice 35 mm or closer for a wide spray product, from the centre of the entrance hole in the drum. Start the chronometer (stopwatch) and following the instructions for use of the product; direct the spray towards the centre of the opposite extremity (cover or plastic film). The aerosol shall be tested in the position it is designed to be used, e.g. upright or inverted; U.K.

(h) Spray until ignition occurs. Stop the chronometer and note the time elapsed. Re-weigh the aerosol dispenser and note its mass; U.K.

(i) Ventilate and clean the drum removing any residue likely to affect subsequent tests. Allow the drum to cool if necessary; U.K.

(j) Repeat the test procedure steps (d) to (i) for another two aerosol dispensers of the same product (three in total, note: each dispenser is only tested once);] U.K.
