Division 4.1.4 Filling

1. (a)

   Aerosol dispensers filled with compressed gas shall not be required to withstand a pressure of more than 9 bars at 50° C.

2. (b)

   Aerosol dispensers filled with dissolved gas shall not be required to withstand a pressure of more than 8 bars at 50° C.

3. (c)

   Aerosol dispensers containing liquefied gas or mixtures of liquefied gas shall not be required to withstand, at 20° C, pressures higher than those shown in the following table:

   Total capacity	Percentage by weight of liquefied gas in the total mixture
   	20 %	50 %	80 %
   50 to 80 ml	3·5 bars	2·8 bars	2·5 bars
   < 80 to 160 ml	3·2 bars	2·5 bars	2·2 bars
   < 160 to 220 ml	2·8 bars	2·1 bars	1·8 bars

This table shows the pressure limits permitted at 20° C in relation to the percentage of gas.

Pressure limits for percentages of gas not shown in the table shall be extrapolated from it.
