Hydraulic pressure test

The internal pressure to be applied (test pressure) shall be 1.5 times the internal pressure at 50 °C,
with a minimum pressure of 1 MPa (10 bar).

 
The hydraulic pressure tests shall be carried out on at least five empty receptacles of each model:
 
(a) until the prescribed test pressure is reached, by which time no leakage or visible permanent 
deformation shall have occurred; and
 
(b)  until leakage or bursting occurs; the dished end, if any, shall yield first and the receptacle 
shall  not leak or burst until a pressure 1.2 times the test pressure has been reached or passed.
 

Tightness (leakproofness) test

Each filled aerosol dispenser or gas cartridge or fuel cell cartridge shall be subjected to a test in a hot
water bath in accordance with 6.2.6.3.1 or an approved water bath alternative in accordance with
6.2.6.3.2.

Hot water bath test

The temperature of the water bath and the duration of the test shall be such that the internal pressure
reaches that which would be reached at 55 °C (50 °C if the liquid phase does not exceed 95% of the
capacity of the aerosol dispenser, gas cartridge or the fuel cell cartridge at 50 °C). If the contents are
sensitive to heat or if the aerosol dispensers, gas cartridges or the fuel cell cartridges are made of
plastics material which softens at this test temperature, the temperature of the bath shall be set at
between 20 °C and 30 °C but, in addition, one aerosol dispenser, gas cartridge or the fuel cell cartridge
in 2 000 shall be tested at the higher temperature.

No leakage or permanent deformation of an aerosol dispenser, gas cartridge or the fuel cell cartridge
may occur, except that a plastic aerosol dispenser, gas cartridge or the fuel cell cartridge may be
deformed through softening provided that it does not leak.

Alternative methods

With the approval of the competent authority alternative methods that provide an equivalent level of
safety may be used provided that the requirements of 6.2.6.3.2.1 and, as appropriate, 6.2.6.3.2.2 or
6.2.6.3.2.3 are met.

Quality system

 Aerosol dispenser, gas cartridge or the fuel cell cartridge fillers and component manufacturers 

shall
have a quality system. The quality system shall implement procedures to ensure that all aerosol 
dispensers, gas cartridges or the fuel cell cartridges that leak or that are deformed are rejected 
and not offered for transport.
 
The quality system shall include:
 
(a)      A description of the organizational structure and responsibilities;
 
(b) The relevant inspection and test, quality control, quality assurance, and process operation 
instructions that will be used;
 
(c)      Quality records, such as inspection reports, test data, calibration data and certificates;
 
(d)      Management reviews to ensure the effective operation of the quality system;
 
(e)       A process for control of documents and their revision;
 
(f) A means for control of non-conforming aerosol dispensers, gas cartridges or the fuel cell  
cartridges;
 
(g)      Training programmes and qualification procedures for relevant personnel; and
 
(h)      Procedures to ensure that there is no damage to the final product.
 
An initial audit and periodic audits shall be conducted to the satisfaction of the competent 
authority.
These audits shall ensure the approved system is and remains adequate and efficient. Any proposed 
ved system shall be notified to the competent authority in advance.
 

Aerosol dispensers

Pressure and leak testing of aerosol dispensers before filling

Each empty aerosol dispenser shall be subjected to a pressure equal to or in excess of the maximum
expected in the filled aerosol dispensers at 55 °C (50 °C if the liquid phase does not exceed 95% of
the capacity of the receptacle at 50 °C). This shall be at least two-thirds of the design pressure of the
aerosol dispenser. If any aerosol dispenser shows evidence of leakage at a rate equal to or greater than
3.3 × 10-2 mbar.l.s-1 at the test pressure, distortion or other defect, it shall be rejected.

Testing of the aerosol dispensers after filling

 
Prior to filling the filler shall ensure that the crimping equipment is set appropriately and the specified
propellant is used.
Each filled aerosol dispenser shall be weighed and leak tested. The leak detection equipment shall be
sufficiently sensitive to detect at least a leak rate of 2.0 × 10-3 mbar.l.s-1 at 20 °C.
Any filled aerosol dispenser that shows evidence of leakage, deformation or excessive mass shall be
rejected.

Gas cartridges and fuel cell cartridges

Pressure testing of gas cartridges and fuel cell cartridges

Each gas cartridge or fuel cell cartridge shall be subjected to a test pressure equal to or in excess of the
maximum expected in the filled receptacle at 55 °C (50 °C if the liquid phase does not exceed 95% of
the capacity of the receptacle at 50 °C). This test pressure shall be that specified for the gas cartridge
or fuel cell cartridge and shall not be less than two thirds the design pressure of the gas cartridge or
fuel cell cartridge. If any gas cartridge or fuel cell cartridge shows evidence of leakage at a rate equal
to or greater than 3.3 × 10-2 mbar.l.s-1 at the test pressure or distortion or any other defect, it shall be
rejected.

Leak testing gas cartridges and fuel cell cartridges

 
Prior to filling and sealing, the filler shall ensure that the closures (if any), and the 
associated   sealing
equipment are closed appropriately and the specified gas is used.
 
Each filled gas cartridge or fuel cell cartridge shall be checked for the correct mass of gas and 
shall be leak tested. The leak detection equipment shall be sufficiently sensitive to detect at 
least a leak rate of 2.0 × 10-3 mbar.l.s-1 at 20 °C.
 
Any gas cartridge or fuel cell cartridge that has gas masses not in conformity with the declared 
mass
limits or shows evidence of leakage or deformation, shall be rejected.
