These requirements apply to flexible IBCs of the following types:
13H1 woven plastics without coating or liner
13H2 woven plastics, coated
13H3 woven plastics with liner
13H4 woven plastics, coated and with liner
13H5 plastics film
13L1 textile without coating or liner
13L2 textile, coated
13L3 textile with liner
13L4 textile, coated and with liner
13M1 paper, multiwall
13M2 paper, multiwall, water resistant
Flexible IBCs are intended for the carriage of solids only.

Bodies shall be manufactured from suitable materials. The strength of the material and the
construction of the flexible IBC shall be appropriate to its capacity and its intended use.

All materials used in the construction of flexible IBCs of types 13M1 and 13M2 shall, after complete
immersion in water for not less than 24 hours, retain at least 85% of the tensile strength as measured
originally on the material conditioned to equilibrium at 67% relative humidity or less.

Seams shall be formed by stitching, heat sealing, gluing or any equivalent method. All stitched seamends
shall be secured.

Flexible IBCs shall provide adequate resistance to ageing and to degradation caused by ultraviolet
radiation or the climatic conditions, or by the substance contained, thereby rendering them appropriate
to their intended use.

For flexible plastics IBCs 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 into 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 material recovered from used receptacles shall be used in the manufacture of IBC bodies.
Production residues or scrap from the same manufacturing process may, however, be used.
Component parts such as fittings and pallet bases may also be used provided such components have
not in any way been damaged in previous use.

When filled, the ratio of height to width shall be not more than 2:1.

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.
