Removable head packagings for liquids shall not be dropped until at least 24 hours after filling and
closing to allow for any possible gasket relaxation.
Target
The target shall be a non-resilient and horizontal surface and shall be:
- Integral and massive enough to be immovable;
- Flat with a surface kept free from local defects capable of influencing the test results;
- Rigid enough to be non-deformable under test conditions and not liable to become damaged by
the tests; and
- Sufficiently large to ensure that the test package falls entirely upon the surface.
Drop height
For solids and liquids, if the test is performed with the solid or liquid to be carried or with another
substance having essentially the same physical characteristics:
|
Packing Group I
|
Packing Group II
|
Packing Group III
|
|
1.8 m
|
1.2 m
|
0.8 m
|
For liquids in single packagings and for inner packagings of combination packagings, if the test is performed with water:
NOTE: The term water includes water/antifreeze solutions with a minimum specific gravity of 0.95 for testing at - 18 °C.
(a) where the substances to be carried have a relative density not exceeding 1.2:
|
Packing Group I
|
Packing Group II
|
Packing Group III
|
|
1.8 m
|
1.2 m
|
0.8 m
|
(b) where the substances to be carried have a relative density exceeding 1.2, the drop height shall be calculated on the basis of the relative density (d) of the substance to be carried, rounded up to the first decimal, as follows:
|
Packing Group I
|
Packing Group II
|
Packing Group III
|
|
d × 1.5 (m)
|
d × 1.0 (m)
|
d × 0.67 (m)
|
(c) for light-gauge metal packagings, marked with symbol "RID/ADR" according to 6.1.3.1(a) (ii) intended for the carriage of substances having a viscosity at 23 °C greater than 200 mm2/s (corresponding to a flow time of 30 seconds with an ISO flow cup having a jet orifice of 6 mm diameter in accordance with ISO Standard 2431:1993)
(i) if the relative density does not exceed 1.2:
|
Packing group II
|
Packing group III
|
|
0.6 m
|
0.4 m
|
|
Packing group II
|
Packing group III
|
|
d × 0.5 m
|
d × 0.33 m
|
|
Packing group II
|
Packing group III
|
|
d × 0.5 m
|
d × 0.33 m
|
(ii) where the substances to be carried have a relative density (d) exceeding 1.2 the drop height shall be calculated on the basis of the relative density (d) of the substance to be carried, rounded up to the first decimal place, as follows:
Criteria for passing the test
Each packaging containing liquid shall be leakproof when equilibrium has been reached between the
internal and external pressures, however for inner packagings of combination packagings and except
for inner receptacles of composite packagings (glass, porcelain or stoneware), marked with the symbol
"RID/ADR" according to 6.1.3.1 (a) (ii) it is not necessary that the pressures be equalized.
Where a packaging for solids undergoes a drop test and its upper face strikes the target, the test sample
passes the test if the entire contents are retained by an inner packaging or inner receptacle (e.g. a
plastics bag), even if the closure while retaining its containment function, is no longer sift-proof.
The packaging or outer packaging of a composite or combination packaging shall not exhibit any
damage liable to affect safety during carriage. Inner receptacles, inner packagings, or articles shall
remain completely within the outer packaging and there shall be no leakage of the filling substance
from the inner receptacle(s) or inner packaging(s).
Neither the outermost ply of a bag nor an outer packaging may exhibit any damage liable to affect
safety during carriage.
A slight discharge from the closure(s) upon impact is not considered to be a failure of the packaging
provided that no further leakage occurs.
No rupture is permitted in packagings for goods of Class 1 which would permit the spillage of loose
explosive substances or articles from the outer packaging.
Leakproofness test
The leakproofness test shall be performed on all design types of packagings intended to contain
liquids; however, this test is not required for
- Inner packagings of combination packagings;
- Inner receptacles of composite packagings (glass, porcelain or stoneware), marked with the
symbol "RID/ADR" according to 6.1.3.1 (a) (ii);
- Light gauge metal packagings, marked with the symbol "RID/ADR" according to 6.1.3.1 (a)
(ii) intended for substances with a viscosity at 23 °C exceeding 200 mm2/s.
Number of test samples: three test samples per design type and manufacturer.
Special preparation of test samples for the test: either vented closures shall be replaced by similar
non-vented closures or the vent shall be sealed.
Test method and pressure to be applied: the packagings including their closures shall be restrained
under water for 5 minutes while an internal air pressure is applied, the method of restraint shall not
affect the results of the test.
The air pressure (gauge) to be applied shall be:
|
Packing Group I
|
Packing Group II
|
Packing Group III
|
|
Not less than 30 kPa (0.3 bar)
|
Not less than 20 kPa (0.2 bar)
|
Not less than 20 kPa (0.2 bar)
|
Other methods at least equally effective may be used.
Criterion for passing the test: there shall be no leakage.
