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.
 

 
With the approval of the competent authority, aerosols and receptacles, small, are not subject to
6.2.6.3.1 and 6.2.6.3.2, if they are required to be sterile but may be adversely affected by water 
bath testing, provided:
(a)       They contain a non-flammable gas and either
 
(i) contain other substances that are constituent  parts  of  pharmaceutical  products  for  
medical, veterinary or similar purposes;
 
(ii)      contain other substances used in the production process for pharmaceutical  products; or
 
(iii)     are used in medical, veterinary or similar applications;
 
(b)  An equivalent level of safety is achieved by the manufacturer's use of alternative methods for 
  leak detection and pressure resistance, such as helium detection and water bathing a statistical 
sample of at least 1 in 2000 from each production batch; and
 
(c)    For pharmaceutical products according to (a) (i) and (iii) above, they are manufactured 
under    the authority of a national health administration. If required by the competent authority, 
the principles of Good Manufacturing Practice (GMP) established by the World Health Organization 
(WHO)3 shall be followed.

6.3

REQUIREMENTS FOR THE CONSTRUCTION AND TESTING OF PACKAGINGS FOR CLASS 6.2 INFECTIOUS SUBSTANCES OF CATEGORY A

NOTE: The requirements of this Chapter don't apply to packagings used for the carriage of Class 6.2
substances according to packing instruction P621 of 4.1.4.1.

General

The requirements of this Chapter apply to packagings intended for the carriage of infectious
substances of Category A.

Requirements for packagings

The requirements for packagings in this section are based on packagings, as specified in 6.1.4,
currently used. In order to take into account progress in science and technology, there is no objection
to the use of packagings having specifications different from those in this Chapter provided that they
are equally effective, acceptable to the competent authority and able successfully to withstand the tests
described in 6.3.5. Methods of testing other than those described in ADR are acceptable provided they
are equivalent, and are recognized by the competent authority.

Packagings shall be manufactured and tested under a quality assurance programme which satisfies the
competent authority in order to ensure that each packaging meets the requirements of this Chapter.
NOTE: ISO 16106:2006 "Packaging – Transport packages for dangerous goods – Dangerous
goods packagings, intermediate bulk containers (IBCs) and large packagings – Guidelines for the
application of ISO 9001" provides acceptable guidance on procedures which may be followed.

Manufacturers and subsequent distributors of packagings shall provide information regarding
procedures to be followed and a description of the types and dimensions of closures (including
required gaskets) and any other components needed to ensure that packages as presented for carriage
are capable of passing the applicable performance tests of this Chapter.

Code for designating types of packagings

The codes for designating types of packagings are set out in 6.1.2.7.

The letters "U" or "W" may follow the packaging code. The letter "U" signifies a special packaging
conforming to the requirements of 6.3.5.1.6. The letter "W" signifies that the packaging, although, of
the same type indicated by the code is manufactured to a specification different from that in 6.1.4 and
is considered equivalent under the requirements of 6.3.2.1.
