Specific requirements for plastics large packagings
The large packaging 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 outer packaging. 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 large packaging 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.
Specific requirements for fibreboard large packagings
50 G rigid fibreboard
Strong and good quality solid or double-faced corrugated fibreboard (single or multiwall) shall be
used, appropriate to the capacity of the large packagings and to their intended use. The water
resistance of the outer surface shall be such that the increase in mass, as determined in a test carried
out over a period of 30 minutes by the Cobb method of determining water absorption, is not greater
than 155 g/m2 - see ISO 535:1991. It shall have proper bending qualities. Fibreboard shall be cut,
creased without scoring, and slotted so as to permit assembly without cracking, surface breaks or
undue bending. The fluting or corrugated fibreboard shall be firmly glued to the facings.
The walls, including top and bottom, shall have a minimum puncture resistance of 15 J measured
according to ISO 3036:1975.
Manufacturing joins in the outer packaging of large packagings shall be made with an appropriate
overlap and shall be taped, glued, stitched with metal staples or fastened by other means at least
equally effective. Where joins are effected by gluing or taping, a water resistant adhesive shall be
used. Metal staples shall pass completely through all pieces to be fastened and be formed or protected
so that any inner liner cannot be abraded or punctured by them.
Any integral pallet base forming part of a large packaging or any detachable pallet shall be suitable for
mechanical handling with the large packaging filled to its maximum permissible gross mass.
The pallet or integral base shall be designed so as to avoid any protrusion of the base of the large
packaging that might be liable to damage in handling.
The body shall be secured to any detachable pallet to ensure stability in handling and carriage. Where
a detachable pallet is used, its top surface shall be free from sharp protrusions that might damage the
Strengthening devices such as timber supports to increase stacking performance may be used but shall
be external to the liner.
Where large packagings are intended for stacking, the bearing surface shall be such as to distribute the
load in a safe manner.
Specific requirements for wooden large packagings
50C natural wood
50F reconstituted wood
The strength of the materials used and the method of construction shall be appropriate to the capacity
and intended use of the large packagings.
