This part of ISO lays down the basic specifications and testing requirements for ISO series 1 thermal containers which are suitable for international exchange and for conveyance by road, rail and sea, including interchange between these forms of transport. The marking requirements for these containers are in accordance with the principles embodied in ISO 6346. The load-bearing capabilities of equipment installed for hanging cargo shall be marked on the inside of the container. If containers are given an atmosphere which could be injurious to health until appropriately vented, suitable markes should be placed alongside each point of access.
