The outer packaging shall conform to the packing group I performance level for solids.

Additional requirements:

1. Fragile articles shall be contained in either a rigid inner packaging or a rigid intermediate packaging.

2.Inner packagings containing sharp objects such as broken glass and needles shall be rigid and resistant to puncture. Outer packagings that are not capable of retaining liquids by design shall be fitted with a liner or suitable measure of retaining liquids.

4.The inner packaging and/or the intermediate packaging may be flexible. When flexible packagings are used, they shall be capable of passing the impact resistance test of at least 165 g according to ISO 7765-1:1988 Plastics film and sheeting - Determination of impact resistance by the free-falling dart method ­ Part 1: Staircase methods and the tear resistance test of at least 480 g in both parallel and perpendicular planes with respect to the length of the bag in accordance with ISO 6383-2:1983 Plastics - Film and sheeting - Determination of tear resistance ­ Part 2: Elmendorf method. The maximum net mass of each flexible inner packaging shall be 30 kg.

5. Each flexible intermediate packaging shall contain only one inner packaging.

6.Inner packagings containing a small amount of free liquid may be included in intermediate packaging provided that there is sufficient absorbent or solidifying material in the inner or intermediate packaging to absorb or solidify all the liquid content present. Suitable absorbent material which may withstand the temperatures and vibrations liable to occur under normal conditions of transport shall be used.

7.Intermediate packagings shall be secured in outer packagings with suitable cushioning and/or absorbent material.
