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:
 
 

Packing group I

Packing group II

Packing group III

1.8 m

1.2 m

0.8 m

 

For inner packagings containing liquids if the test is performed with water:

 

(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

1.5 (m)

 1.0 (m)

 0.67 (m)

 

Criteria for passing the test

The large packaging shall not exhibit any damage liable to affect safety during carriage. There shall be
no leakage of the filling substance from inner packaging(s) or article(s).
