5 Design requirements

5.1 General

All containers shall be capable of fulfilling the following requirements.

The strength requirements for containers are given in diagrammatic form in Annex A (these requirements are applicable to all containers except where otherwise stated). They apply to containers as complete units.

The strength requirements for corner fittings (see also 5.2) are given in ISO 1161.

Not for Resale, 11/26/2018 09:00:32 MSTNo reproduction or networking permitted without license from IHS

The container shall be capable of withstanding the loads and loadings detailed in Clause 6.

As the effects of loads encountered under any dynamic operating condition should only approach, but not exceed, the effects of the corresponding test loads, it is implicit that the capabilities of containers indicated in Annex A and demonstrated by the test described in Clause 6 shall not be exceeded in any mode of operation.

Any closure in a container which, if unsecured, could lead to a hazardous situation, shall be provided with an adequate securing system having external indication of the positive securement of that closure in the appropriate operating position.

In particular, doors should be capable of being securely fastened in the open or closed position.

Any removable roof or roof section shall be fitted with locking devices such that an observer at ground level can check (when the container is on a rail or highway carrying vehicle) that its roof is secured.

All closed containers and all open containers fitted with covers which were designed for them shall be weatherproof as required by test No. 13 (see 6.14).

5.2 Corner fittings

All containers shall be equipped with top and bottom corner fittings 1EEE and 1EE units shall also have intermediate fittings in the 1 AAA/1 AA/1 A position, according to ISO 1161.

The upper faces of the top corner fittings shall protrude above the top of the container by a minimum of 6 mm (see 5.3.4). The “top of the container” means the highest level of the cover of the container, for example the level of the top of a soft cover. However, if reinforced zones or doubler plates are provided to afford protection to the roof in the vicinity of the top corner fittings, such plates and their securements shall not protrude above the upper faces of the top corner fittings. These plates shall not extend more than 750 mm from either end of the container or on either side of intermediate fittings but may extend the full width.

5.3 Base structure

5.3.1 All containers shall be capable of being supported by their bottom corner fittings only.

5.3.2 All containers, other than 1 D and 1 DX, shall also be capable of being supported only by load transfer areas in their base structure.

5.3.2.1 Consequently, these containers shall have end transverse members and sufficient intermediate load transfer areas (or a flat underside) of sufficient strength to permit vertical load transfer to or from the longitudinal member of a carrying vehicle. Such longitudinal members are assumed to lie within the two 250 mm wide zones defined by the broken lines in Annex B of ISO 668:1995.

5.3.2.2 The lower faces of the load transfer areas, including those of the end transverse members, shall be in one plane located 12,5 −

1,5 5 mm above the plane of the bottom faces of the lower corner fittings of the container. Apart from the bottom corner fittings and bottom side rails, no part of the container shall project below this plane.

However, doubler plates may be provided in the vicinity of the bottom corner fittings to afford protection to the understructure.

Such plates shall not extend more than 550 mm from the outer end and not more than 470 mm from the side faces of the bottom corner fittings, and their lower faces shall be at least 5 mm above the lower faces of the bottom corner fittings of the container.

5.3.2.3 The transfer of load between the underside of the bottom side rails and carrying vehicles is not envisaged.

The transfer of load between side rails and handling equipment should only occur when provisions have been made in accordance with 5.8.1 and 5.8.2.

5.3.2.4 Containers having all their intermediate transverse members spaced at 1 000 mm apart or less (or having a flat underside) shall be deemed to comply with the requirements laid down in 5.3.2.1.

5.3.2.5 Requirements for containers not having transverse members spaced 1 000 mm apart or less (and not having a flat underside) are given in Annex B of ISO 668:1995.

5.3.3 For containers 1 D and 1 DX, the level of the underside of the base structure is not specified, except in so far as it is implied in 5.3.4.

5.3.4 For all containers under dynamic conditions, or the static equivalent thereof, with the container having a load uniformly distributed over the floor in such a way that the combined mass of the container and test load is equal to 1,8 R, no part of the base of the container shall deflect more than 6 mm below the base plane (bottom faces of the lower corner fittings).

5.3.5 The base structure shall be designed to withstand all forces, particularly lateral forces, induced by the cargo in service. This is particularly important where provisions are made for securement of cargo to the base structure of the container.

5.3.6 1EEE and 1EE units shall have recesses longitudinally-outboard of each of their fittings in the 1 AAA/1 AA/1 A position. These recesses shall extend vertically to not less than 76 mm above the plane of the bottom faces of the fittings in the 1 AAA/1 AA/1 A position, shall extend longitudinally from the longitudinally outboard faces of the fittings in the 1 AAA/1 AA/1 A position outboard, to not less than 254 mm from the centrelines of the bottom apertures of the fittings in the 1 AAA/1 AA/1 A position and shall extend laterally from the external width of the container inboard not less than 154 mm. See Figure 1.

5.4 End structure

For all containers other than 1D and 1DX, the sideways deflection of the top of the container with respect to the bottom of the container, at the time it is under full transverse rigidity test conditions, shall not cause the sum of the changes in length of the two diagonals to exceed 60 mm.

5.5 Side structure

For all containers other than 1D and lDX, the longitudinal deflection of the top of the container with respect to the bottom of the container, at the time it is under full longitudinal rigidity test conditions, shall not exceed 25 mm.

5.6 Walls

Where openings are provided in end or side walls, the ability of these walls to withstand tests Nos. 5 and 6 shall not be impaired.

5.7 Door opening

Each container shall be provide with a door opening at least at one end.

All door openings and end openings shall be as large as possible.

Closed-type containers designated 1 EEE, 1AAA, and 1BBB (Type according ISO 6346:1995, Amd 3:2013, Annex E) shall have a door opening, preferably having dimensions equal to those of the internal cross-section of the containers and, in any case, not less than 2 566 mm high and 2 286 mm wide.

Closed-type containers designated 1 EE, 1 AA, 1 BB and 1 CC (Type according ISO 6346:1995 Amd 3:2013, Annex E) shall have a door opening, preferably having dimensions equal to those of the internal cross-section of the containers, and, in any case, not less than 2 261 mm high, and 2 286 mm wide.

Closed-type containers designated 1E, 1B, 1C and 1D (Type according ISO 6346:1995 Amd 3:2012, Annex E) shall have a door opening, preferably having dimensions equal to those of the internal cross-section of the containers, and, in any case, not less than 2 134 mm high, and 2 286 mm wide.

Container doors should be designed so that entry into the container via either of the doors can be detected by verifying the condition of the seal that has been affixed to the container. All door openings shall be fitted to accept an ISO compliant high security seal (see ISO 17712) in a manner that precludes opening or gapping of either of the doors without first removing the seal.

The design of the container shall be such that the door constrained by the seal must be opened before the other door can be opened. The mechanism in which the seal is fitted shall either be welded to a significant structural member of the container or otherwise be constructed so that the mechanism or seal cannot be removed and the door opened or gapped without first having to break the seal. Seal-affixing mechanisms that do not meet these basic requirements shall not be fitted onto the container.

A securing plate (also known as “custom plate”) shall be installed on the inside, above the mid-point, of the left door in order to prevent the left door from being opened without first opening the right hand door. This plate shall be painted a contrasting colour so it is readily visible when the right hand door is opened. Other design features that form an “interlock” between the two doors or otherwise preclude manipulation and opening of the unsealed door without breaking the seal are equally acceptable.

The door hinges shall either be welded to the door panel or, if affixed with fasteners, affixed with TIR approved fasteners that are further protected from removal by a suitable shield or equivalent design feature. Hinges pin shall be welded in place or otherwise protected to preclude their removal.

An elongated door handle hub (sometimes referred to as a “security hub”) that extends at least 25mm below the rivet hole or pivot point, shall be used on the right hand door to prevent the handle from being removed even if the rivet is removed.

5.8 Requirements — Optional features

5.8.1 Fork-lift pockets

5.8.1.1 Fork-lift pockets used for handling 1 CC, 1 C, 1 CX, 1 D and 1 DX containers in the loaded or unloaded condition may be provided as optional features.

Fork-lift pockets shall not be provided on 1 EEE, 1 EE, 1AAA, 1AA, 1A, 1AX, 1BBB, 1BB, 1B and 1BX containers.

5.8.1.2 Where a set of fork-lift pockets has been fitted as in 5.8.1.1, a second set of fork-lift pockets may, in addition, be provided on 1 CC, 1C and 1 CX containers for empty handling only.

5.8.1.3 The fork-lift pockets, where provided, shall meet the dimensional requirements specified in Annex C and shall pass completely through the base structure of the container so that lifting devices may be inserted from either side. It is not necessary for the base of the fork-lift pockets to be the full width of the container but it shall be provided in the vicinity of each end of the fork pockets.

5.8.2 Cargo securing devices

Cargo securing devices may be provided as optional features in all series 1 general purpose containers.

The requirements for such devices are specified in Annex C.

5.8.3 Cargo shoring slots

Cargo shoring slots are optional features in all series 1 general purpose containers. The requirements for this feature are specified in Annex D.

6 Testing

6.1 General

Unless otherwise stated, containers complying with the design requirements specified in Clause 5 shall, in addition, be capable of withstanding the tests specified in 6.2 to 6.14, as applicable. Containers shall be tested in the condition in which they are designed to be operated. In all cases the forces shall be applied in such a manner that rotation of the planes through which the forces are applied and the container is supported is minimized. The force must be centred over the offset position.

However, the weatherproofness test shall always be performed after all structural test have been completed.

6.1.1 The symbol P denotes the maximum payload of the container to be tested, that is:

P = R - T where

R is the rating;

T is the tare.

NOTE R, P and T, by definition, are in units of mass. Where test requirements are based on the gravitational forces derived from these values, those forces, which are inertial forces, are indicated thus:

Rg, Pg, Tg the units of which are in Newton or multiples thereof.

The word “load”, when used to describe a physical quantity to which units may be ascribed, implies mass.

The word “loading”, for example as in “internal loading”, implies force.

6.1.2 The test loads or loadings within the container shall be uniformly distributed.

6.1.3 The test load or loading specified in all of the following tests are the minimum requirements.

6.1.4 The dimensional requirements to which reference is made in the requirements subclause after each test are those specified in:

a) the dimensional and design requirement clauses of this part of ISO 1496;

b) ISO 668;

c) ISO 1161.

6.2 Test No. 1 — Stacking

6.2.1 General

This test shall be carried out to prove the ability of a fully loaded container to support a superimposed mass of containers, taking into account conditions aboard ships at sea and the relative eccentricities between superimposed containers.

Cargo securing devices may be provided as optional features in all series 1 general purpose containers.

Table 3 specifies the force to be applied as a test to each pair of corner fittings and the superimposed mass that the test force represents.

6.2.2 Procedure

The container shall be placed on four level pads, one under each bottom corner fitting.

The pads shall be centralized under the fittings, and shall be substantially of the same plan dimensions as the fittings. The container shall have a load uniformly distributed over the floor in such a way that the combined mass of the container and the test load is equal to 1,8 R.

The container shall be subjected to vertical forces, applied either to all four corner fittings simultaneously or to each pair of end fittings, at the appropriate level specified in Table 3. The forces shall be applied through a test fixture equipped with corner fittings as specified in ISO 1161, or equivalent fittings which have imprints of the same geometry (i.e. with the same external dimensions, chamfered aperture and rounded edges) as the bottom face of the bottom corner fitting specified in ISO 1161. If equivalent fittings are used, they shall be designed to produce the same effect on the container under the test loads as when corner fittings are used.

In all cases, the forces shall be applied in such a manner that rotation of the planes through which the forces are applied and on which the container is supported is minimized. The force must be centred over off head position.

Each corner fitting or equivalent test fitting shall be offset in the same direction by 25,4 mm laterally and 38 mm longitudinally.
