Series 1 freight containers - Specification and testing - Part 5: Platform and platform-based containers

1 Scope

This document specifies the basic specifications and testing requirements for ISO 668 series 1 freight containers of the platform and platform-based types designated 1AAA, 1AA, 1A, 1AX, 1BBB, 1BB, 1B, 1BX, 1CC, 1C and 1CX which are suitable for international exchange and for conveyance by road, rail and sea, including interchange between these forms of transport, with certain limitations (for example, when loaded, platforms cannot be stacked or top lifted by means of conventional spreaders).

The container types covered by this document are given in Table 1.

3 Terms and definitions

For the purposes of this document, the terms and definitions given in ISO 830 and the following apply.

ISO and IEC maintain terminological databases for use in standardization at the following addresses:

——ISO Online browsing platform: available at https://www.iso.org/obp

——IEC Electropedia: available at http://www.electropedia.org/

3.1
platform
flat structure having no superstructure

Note: The equipment covered by this document is defined as a loadable platform having no superstructure whatsoever but having the same length and width as the base of series 1 containers, and equipped with top and bottom corner fittings, located in plan view as on other series 1 containers, so that some securing and lifting devices used on other series 1 containers of the same length can also be used on platforms.

3.2
platform-based container
container which has no side walls but has a base similar to that of a platform container

3.3
incomplete superstructure
superstructure lacking any permanently fixed longitudinal load-carrying structure between the ends other than at the base

3.4
interlocked pile
number of platform containers or folding platform-based containers (3.2), with ends folded down, which are interlocked to form a unit (module)

Note: See 4.1.3.

4 Dimensions and ratings

4.1 External dimensions

4.1.1 The overall external dimensions and tolerances of the freight containers covered by this document shall be those established in ISO 668, except that the requirements for the overall top lengths, L, of platform-based containers with incomplete superstructure may be relaxed to the extreme limits specified in Table 2.

Any movement of the corner posts resulting from the change from the empty to the fully loaded condition of the container should, as far as practicable, be equally disposed about the mean of the values of Lmax and Lmin.

Taking into account the fact that the mechanism of the folding end structures may introduce natural play, the values of Lmax and Lmin specified in Table 2 shall be met. Failure to comply with this requirement is liable to lead to handling difficulties.

4.1.2 No part of the platform or platform-based container shall project beyond the envelope defined by the overall external dimensions specified in:

——ISO 668 for the plan dimensions of the base structure of all containers, the plan dimensions of the top part of container with complete superstructure, or the overall maximum height of all containers which may also be of reduced dimensions; or

——Table 2 for the plan dimensions of the top part of containers with incomplete superstructure.

4.1.3 An interlocked pile of either platform or folded platform-based containers shall have the plan dimensions specified in ISO 668 and a pile height not exceeding 2896 mm.

4.2 Internal dimensions

Internal dimensions are not specified; however, minimum internal dimensions of existing 1CC, 1C and 1CX platform-based containers for the carriage of small containers are given in Annex D. The values are given as a guide to the design of small intermodal containers.

4.3 Ratings

The values of the rating, R, the maximum gross mass of these containers, shall be those
specified in ISO 668.
