Preparation of large packaging for test
The large packaging shall be loaded to twice its maximum permissible gross mass. A flexible large
packaging shall be loaded to six times its maximum permissible gross mass, the load being evenly
distributed.
Method of testing
The large packaging shall be lifted in the manner for which it is designed until clear of the floor and
maintained in that position for a period of five minutes.
Criteria for passing the test
(a) Metal and rigid plastics large packagings: no permanent deformation which renders the large
packaging, including the base pallet, if any, unsafe for carriage and no loss of contents;
(b) Flexible large packagings: no damage to the large packaging or its lifting devices which
renders the large packaging unsafe for carriage or handling and no loss of contents.
Stacking test
Applicability
For all types of large packagings which are designed to be stacked on each other, as a design type test.
Preparation of large packaging for test
The large packaging shall be filled to its maximum permissible gross mass.
Method of testing
The large packaging shall be placed on its base on level hard ground and subjected to a uniformly
distributed superimposed test load (see 6.6.5.3.3.4) for a period of at least five minutes, large
packagings of wood, fibreboard and plastics materials for a period of 24 h.
Calculation of superimposed test load
The load to be placed on the large packagings shall be 1.8 times the combined maximum permissible
gross mass of the number of similar large packagings that may be stacked on top of the large
packagings during carriage.
Criteria for passing the test
(a) All types of large packagings other than flexible large packagings: no permanent deformation
which renders the large packaging including the base pallet, if any, unsafe for carriage and no
loss of contents;
(b) Flexible large packagings: no deterioration of the body which renders the large packaging
unsafe for carriage and no loss of contents.
Drop test
Applicability
For all types of large packagings as a design type test.
Preparation of large packaging for testing
The large packaging shall be filled in accordance with 6.6.5.2.1
Method of testing
The large packaging shall be dropped onto a non resilient, horizontal, flat, massive and rigid surface in
conformity with the requirements of 6.1.5.3.4, in such a manner as to ensure that the point of impact is
that part of the base of the large packaging considered to be the most vulnerable.
Drop height
NOTE: Large packagings for substances and articles of Class 1 shall be tested at the packing group
II performance level.
For inner packagings containing solid or liquid substances or articles, if the test is performed with the
solid, liquid or articles to be carried, or with another substance or article having essentially the same
characteristics:
