Conformity to design type
The marks indicate that IBCs correspond to a successfully tested design type and that the requirements
referred to in the certificate have been met.
Marking of remanufactured composite IBCs (31HZ1)
The marks specified in 188.8.131.52.1 and 184.108.40.206 shall be removed from the original IBC or made
permanently illegible and new marks shall be applied to an IBC remanufactured in accordance with
IBCs shall be resistant to or adequately protected from deterioration due to the external environment.
IBCs shall be so constructed and closed that none of the contents can escape under normal conditions
of carriage including the effect of vibration, or by changes in temperature, humidity or pressure.
IBCs and their closures shall be constructed of materials compatible with their contents, or be
protected internally, so that they are not liable:
(a) To be attacked by the contents so as to make their use dangerous;
(b) To cause the contents to react or decompose, or form harmful or dangerous compounds with
Gaskets, where used, shall be made of materials not subject to attack by the contents of the IBCs.
All service equipment shall be so positioned or protected as to minimize the risk of escape of the
contents owing to damage during handling and carriage.
IBCs, their attachments and their service and structural equipment shall be designed to withstand,
without loss of contents, the internal pressure of the contents and the stresses of normal handling and
carriage. IBCs intended for stacking shall be designed for stacking. Any lifting or securing features of
IBCs shall be of sufficient strength to withstand the normal conditions of handling and carriage
without gross distortion or failure and shall be so positioned that no undue stress is caused in any part
of the IBC.
Where an IBC consists of a body within a framework it shall be so constructed that:
(a) The body does not chafe or rub against the framework so as to cause material damage to the
(b) The body is retained within the framework at all times;
(c) The items of equipment are fixed in such a way that they cannot be damaged if the connections
between body and frame allow relative expansion or movement.
Where a bottom discharge valve is fitted, it shall be capable of being made secure in the closed
position and the whole discharge system shall be suitably protected from damage. Valves having lever
closures shall be able to be secured against accidental opening and the open or closed position shall be
readily apparent. For IBCs containing liquids, a secondary means of sealing the discharge aperture
shall also be provided, e.g. a blank flange or equivalent device.
Testing, certification and inspection
Quality assurance: the IBCs shall be manufactured, remanufactured, repaired and tested under a
quality assurance programme which satisfies the competent authority, in order to ensure that each
manufactured, remanufactured or repaired IBC meets the requirements of this Chapter.
NOTE: ISO 16106:2006 "Packaging – Transport packages for dangerous goods – Dangerous
goods packagings, intermediate bulk containers (IBCs) and large packagings – Guidelines for the
application of ISO 9001" provides acceptable guidance on procedures which may be followed.
Test requirements: IBCs shall be subject to design type tests and, if applicable, to initial and periodic
inspections and tests in accordance with 220.127.116.11.
