The liner shall be made of a suitable material. The strength of the material used and the construction
of the liner shall be appropriate to the capacity of the IBC and the intended use. Joins and closures
shall be siftproof and capable of withstanding pressures and impacts liable to occur under normal
conditions of handling and carriage.

Specific requirements for rigid plastics IBCs

These requirements apply to rigid plastics IBCs for the carriage of solids or liquids. Rigid plastics
IBCs are of the following types:
11H1 fitted with structural equipment designed to withstand the whole load when IBCs are
stacked, for solids which are filled or discharged by gravity
11H2 freestanding, for solids which are filled or discharged by gravity
21H1 fitted with structural equipment designed to withstand the whole load when IBCs are
stacked, for solids which are filled or discharged under pressure
21H2 freestanding, for solids which are filled or discharged under pressure
31H1 fitted with structural equipment designed to withstand the whole load when IBCs are
stacked, for liquids
31H2 freestanding, for liquids.

The body shall be manufactured from suitable plastics material of known specifications and be of
adequate strength in relation to its capacity and its intended use. The material shall be adequately
resistant to ageing and to degradation caused by the substance contained or, where relevant, by
ultraviolet radiation. Low temperature performance shall be taken into account when appropriate. Any
permeation of the substance contained shall not constitute a danger under normal conditions of
carriage.

Where protection against ultraviolet radiation is required, it shall be provided by the addition of
carbon black or other suitable pigments or inhibitors. These additives shall be compatible with the
contents and remain effective throughout the life of the body. Where use is made of carbon black,
pigments or inhibitors other than those used in the manufacture of the tested design type, re-testing
may be waived if changes in the carbon black content, the pigment content or the inhibitor content do
not adversely affect the physical properties of the material of construction.

Additives may be incorporated in the material of the body to improve the resistance to ageing or to
serve other purposes, provided that these do not adversely affect the physical or chemical properties of
the material.

No used material other than production residues or regrind from the same manufacturing process may
be used in the manufacture of rigid plastics IBCs.

Specific requirements for composite IBCs with plastics inner receptacles

These requirements apply to composite IBCs for the carriage of solids and liquids of the following
types:
11HZ1 Composite IBCs with a rigid plastics inner receptacle, for solids filled or discharged by
gravity
11HZ2 Composite IBCs with a flexible plastics inner receptacle, for solids filled or discharged by
gravity
21HZ1 Composite IBCs with a rigid plastics inner receptacle, for solids filled or discharged under
pressure
21HZ2 Composite IBCs with a flexible plastics inner receptacle, for solids filled or discharged
under pressure
31HZ1 Composite IBCs with a rigid plastics inner receptacle, for liquids
31HZ2 Composite IBCs with a flexible plastics inner receptacle, for liquids.
This code shall be completed by replacing the letter Z by a capital letter in accordance with 6.5.1.4.1
(b) to indicate the nature of the material used for the outer casing.

The inner receptacle is not intended to perform a containment function without its outer casing. A
"rigid" inner receptacle is a receptacle which retains its general shape when empty without closures in
place and without benefit of the outer casing. Any inner receptacle that is not "rigid" is considered to
be "flexible".

 

The outer casing normally consists of rigid material formed so as to protect the inner receptacle from
physical damage during handling and carriage but is not intended to perform the containment
function. It includes the base pallet where appropriate.

A composite IBC with a fully enclosing outer casing shall be so designed that the integrity of the inner
receptacle may be readily assessed following the leakproofness and hydraulic pressure tests.

IBCs of type 31HZ2 shall be limited to a capacity of not more than 1 250 litres.

The inner receptacle shall be manufactured from suitable plastics material of known specifications and
be of adequate strength in relation to its capacity and its intended use. The material shall be
adequately resistant to ageing and to degradation caused by the substance contained or, where
relevant, by ultraviolet radiation. Low temperature performance shall be taken into account when
appropriate. Any permeation of the substance contained shall not constitute a danger under normal
conditions of carriage.

Where protection against ultraviolet radiation is required, it shall be provided by the addition of
carbon black or other suitable pigments or inhibitors. These additives shall be compatible with the
contents and remain effective throughout the life of the inner receptacle. Where use is made of carbon
black, pigments or inhibitors, other than those used in the manufacture of the tested design type,
retesting may be waived if changes in carbon black content, the pigment content or the inhibitor
content do not adversely affect the physical properties of the material of construction.
