The leakproofness test shall be performed on all design types of packagings intended to contain liquids; however, this test is not required for the inner packagings of combination packagings.
Number of test samples: three test samples per design type and manufacturer.
Special preparation of test samples for the test: vented closures shall either 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) |
