Dangerous Goods by Road
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.
Internal pressure (hydraulic) test
Packagings to be tested
The internal pressure (hydraulic) test shall be carried out on all design types of metal, plastics
and
composite packagings intended to contain liquids. 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 packagings for testing: either vented closures shall be replaced by similar
non-vented closures or the vent shall be sealed.
