Number of test samples: three test samples per design type and manufacturer.

Special preparation of packagings for testing: either vented closures shall be replaced by similar
non-vented closures or the vent shall be sealed.

 
Test method and pressure to be applied: metal packagings and composite packagings (glass, porcelain 
or stoneware), including their closures, shall be subjected to the test pressure for 5 minutes. 
Plastics packagings and composite packagings (plastics material) including their closures shall be 
subjected to the test pressure for  30  minutes.  This  pressure  is  the  one  to  be  included  
in  the  mark  required by 6.1.3.1 (d). The manner in which the packagings are supported shall not 
invalidate the test. The test pressure shall be applied continuously and evenly; it shall be kept 
constant throughout the test period. The hydraulic pressure (gauge) applied, as determined by any 
one of the following methods, shall be:
 
(a) not less than the total gauge pressure measured in the packaging (i.e. the vapour pressure of 
the filling liquid and the partial pressure of the air or other inert gases, minus 100 kPa) at 55 
°C, multiplied by a safety factor of 1.5; this total gauge pressure shall be determined on the 
basis of a maximum degree of filling in accordance with 4.1.1.4 and a filling temperature of l5 °C; 
or
 
(b)  not less than 1.75 times the vapour pressure at 50 °C of the liquid to be carried, minus 100 
kPa  but with a minimum test pressure of 100 kPa; or
 
(c)   not less than 1.5 times the vapour pressure at 55 °C of the liquid to be carried, minus 100 
kPa   but with a minimum test pressure of 100 kPa.
 

In addition, packagings intended to contain liquids of packing group I shall be tested to a minimum
test pressure of 250 kPa (gauge) for a test period of 5 or 30 minutes depending upon the material of
construction of the packaging.

Stacking test

Criterion for passing the test: no packaging may leak.

Stacking test

All design types of packagings other than bags, and other than non-stackable composite packagings
(glass, porcelain, or stoneware) marked with the symbol "RID/ADR" according to 6.1.3.1 (a) (ii), shall
be subjected to a stacking test.

Number of test samples: three test samples per design type and manufacturer.

Test method: the test sample shall be subjected to a force applied to the top surface of the test sample
equivalent to the total weight of identical packages which might be stacked on it during carriage;
where the contents of the test sample are liquids with relative density different from that of the liquid
to be carried, the force shall be calculated in relation to the latter. The minimum height of the stack
including the test sample shall be 3 metres. The duration of the test shall be 24 hours except that
plastics drums, jerricans, and composite packagings 6HH1 and 6HH2 intended for liquids shall be
subjected to the stacking test for a period of 28 days at a temperature of not less than 40 °C.
For the test in accordance with 6.1.5.2.5, the original filling substance shall be used. For the test in
accordance with 6.1.5.2.6, a stacking test shall be carried out with a standard liquid.

 

Criteria for passing the test: no test sample shall leak. In composite packagings or combination
packagings, there shall be no leakage of the filling substance from the inner receptacle or inner
packaging. No test sample shall show any deterioration which could adversely affect transport safety
or any distortion liable to reduce its strength or cause instability in stacks of packages. Plastics
packagings shall be cooled to ambient temperature before the assessment.

Supplementary permeability test for plastics drums and jerricans in accordance with 6.1.4.8 and for composite packagings (plastics material) in accordance with 6.1.4.19 intended for the carriage of liquids having a flash-point ≤ 60 °C, other than 6HA1 packagings

Polyethylene packagings need be subjected to this test only if they are to be approved for the carriage
of benzene, toluene, xylene or mixtures and preparations containing those substances.

Number of test samples: three packagings per design type and manufacturer.

Special preparation of the test sample for the test: the test samples are to be pre-stored with the
original filling substance in accordance with 6.1.5.2.5, or, for polyethylene packagings, with the
standard liquid mixture of hydrocarbons (white spirit) in accordance with 6.1.5.2.6.

Test method: the test samples filled with the substance for which the packaging is to be approved shall
be weighed before and after storage for 28 days at 23 °C and 50% relative atmospheric humidity. For
polyethylene packagings, the test may be carried out with the standard liquid mixture of hydrocarbons
(white spirit) in place of benzene, toluene or xylene.

Criterion for passing the test: permeability shall not exceed 0.008 g/l.h.
