Introduction

In setting the requirements of this Annex, it is implicit that in all phases of the operation of containers the forces as a result of motion, location, stacking and weight of the loaded container and external forces will not exceed the design strength of the container. In particular, the following assumptions have been made:

(a) the container will so be restrained that it is not subjected to forces in excess of those for which it has been designed;

(b) the container will have its cargo stowed in accordance with the recommended practices of the trade so that the cargo does not impose upon the container forces in excess of those for which it has been designed.

Construction

1. A container made from any suitable material which satisfactorily performs the following tests without sustaining any permanent deformation or abnormality which would render it incapable of being used for its designed purpose, shall be considered safe.

2. The dimensions, positioning and associated tolerances of corner fittings shall be checked having regard to the lifting and securing systems in which they will function.

3. When containers are provided with special fittings for use only when such containers are empty, this restriction shall be marked on the container.

Test loads and test procedures

Where appropriate to the design of the container, the following test loads and test procedures shall be applied to all kinds of containers under test:

______________________________________________________________________

TEST LOADINGS AND APPLIED FORCES TEST PROCEDURES

______________________________________________________________________

The container, having the prescribed INTERNAL LOADING, shall be lifted in such a way that no significant acceleration forces are applied. After lifting, the container shall be suspended or supported for five minutes and then lowered to the ground.

1. For conditions of international transport where the maximum vertical acceleration forces vary significantly from 1.8 g and when the container is reliably and effectively limited to such conditions of transport, the stacking load may be varied by the appropriate ratio of acceleration forces.

2. On successful completion of this test the container may be rated for the allowable superimposed static stacking weight which should be indicated on the Safety Approval Plate against the heading "Allowable stacking weight for 1.8 g (kilogrammes and lbs)".

Internal loading: 

A uniformly distributed load such that the combined weight of container and test load is equal to 1.8 R.	The container, having the prescribed INTERNAL LOADING, shall be placed on four level pads which are in turn supported on a rigid horizontal surface, one under each bottom corner fitting or equivalent corner structure. The pads shall be centralized under the fittings and shall be of approximately the same plan dimensions as the fittings.
Externally applied forces:
Such as to subject each of the four top corner fittings to a vertical downward force equal to 1/4 x 1.8 x the allowable superimposed static stacking weight.	Each EXTERNALLY APPLIED FORCE shall be applied to each of the corner fittings through corresponding test corner fitting or through a pad of the same plan dimensions. The test corner fitting or pad shall be offset with respect to the top corner fitting of the container by 25 mm (1 in.) laterally and 38 mm (11/2 in.) longitudinally.

Internal loading:

None.

Externally applied forces:

A concentrated load of 300 kg (660 lb) uniformly distributed over an area of 600 mm x 300 mm (24 in. x 12 in.)

The EXTERNALLY APPLIED FORCES shall be applied vertically downwards to the outer surface of the weakest area of the roof of the container.

Internal loading:

Two concentrated loads each of 2,730 kg (6,000 lb) and each applied to the container floor through a contact area of 142 cm2 (22 sq. in.)	The test should be made with the container resting on four levels supports under its four bottom corners in such a manner that the base structure of the container is free to deflect.
	A testing device loaded to a weight of 5,460 kilogrammes (12,000 lbs) that is 2,730 kg (6,000 lbs) on each of two surfaces having, when loaded, a total contact area of 284 cm2 (44 sq. in.) that is 142 cm2 (22 sq. in.) on each surface, the surface width being 180 mm (7 in.) spaced 760 mm (30 in.) apart, centre to centre, should be manoeuvred over the entire floor area of the container.

Externally applied forces:

None.

Internal loading:

None.	The container in tare condition shall be placed on four level supports one under each bottom corner and shall be restrained against lateral and vertical movement by means of anchor devices so arranged that the lateral restraint is provided only at the bottom corners diagonally opposite to those at which the forces are applied.
Externally applied forces: Such as to rack the end structures of the container sideways. The forces shall be equal to those for which the container was designed.	The EXTERNALLY APPLIED FORCE shall be applied either separately or simultaneously to each of the top corner fittings on one side of the container in lines parallel both to the base and to the planes of the ends of the container. The forces shall be applied first towards and then away from the top corner fittings. In the case of containers in which each end is symmetrical about its own vertical centreline, one side only need be tested, but both sides of containers with asymmetric ends shall be tested.

When designing and constructing containers, it must be borne in mind that containers, when carried by inland modes of transport may sustain accelerations of 2 g applied horizontally in a longitudinal direction.

Internal loading:

A uniformly distributed load, such that the combined weight of a container and test load is equal to the maximum operating gross weight or rating, R.	The container having the prescribed INTERNAL LOADING shall be restrained longitudinally by securing the two bottom corner fittings or equivalent corner structures at one end to suitable anchor points.
Externally applied forces:
Such as to subject each side of the container to longitudinal compressive and tensile forces of magnitude R, that is, a combined force of 2R on the base of the container as a whole.	The EXTERNALLY APPLIED FORCES shall be applied first towards and then away from the anchor points. Each side of the container shall be tested.

The end walls should be capable of withstanding a load of not less than 0.4 times the maximum permissible payload. If, however, the end walls are designed to withstand a load of less or greater than 0.4 times the maximum permissible payload such a strength factor shall be indicated on the Safety Approval Plate in accordance with Annex I, Regulation 1.

Internal loading:

Such as to subject the inside of an end-wall to a uniformly distributed load of 0.4P or such other load for which the container may be designed.	The prescribed INTERNAL LOADING shall be applied as follows: Both ends of container shall be tested except where the ends are identical only one end need be tested. The end-walls of containers which do not have open sides or side doors may be tested separately or simultaneously. The end-walls of containers which do have open sides or side doors should be tested separately. When the ends are tested separately the reactions to the forces applied to the end-wall shall be confined to the base structure of the container.
Externally applied forces:
None.

The side-walls should be capable of withstanding a load of not less than 0.6 times the maximum permissible payload. If, however, the side-walls are designed to withstand a load of less or greater than 0.6 times the maximum permissible payload, such a strength factor should be indicated on the Safety Approval Plate in accordance with Annex I, Regulation 1.

Internal loading:

Such as to subject the inside of a side-wall to a uniformly distributed load of 0.6P or such other load for which the container may be designed.	The prescribed INTERNAL LOADING shall be applied as follows: Both sides of a container shall be tested except where the sides are identical only one side need be tested. Side-walls shall be tested separately and the reactions to the internal loading shall be confined to the corner fittings or equivalent corner structures. Open topped containers shall be tested in the condition in which they are designed to be operated, for example, with removable top members in position.
Externally applied forces:
None.
