Drop test

Applicability

For all types of IBCs, as a design type test.

Preparation of the IBC for test

(a) Metal IBCs: the IBC shall be filled to not less than 95% of its maximum capacity for solids or
98% of its maximum capacity for liquids. Pressure-relief devices shall be removed and their
apertures plugged, or shall be rendered inoperative;
(b) Flexible IBCs: the IBC shall be filled to the maximum permissible gross mass, the contents
being evenly distributed;
(c) Rigid plastics and composite IBCs: the IBC shall be filled to not less than 95% of its maximum
capacity for solids or 98% of its maximum capacity for liquids. Arrangements provided for
pressure relief may be removed and plugged or rendered inoperative. Testing of IBCs shall be
carried out when the temperature of the test sample and its contents has been reduced to
minus 18 °C or lower. Where test samples of composite IBCs are prepared in this way the
conditioning specified in 6.5.6.3.1 may be waived. Test liquids shall be kept in the liquid state,
if necessary by the addition of anti-freeze. This conditioning may be disregarded if the
materials in question are of sufficient ductility and tensile strength at low temperatures;
(d) Fibreboard and wooden IBCs: The IBC shall be filled to not less than 95% of its maximum
capacity.

Method of testing

The IBC shall be dropped on its base onto a non-resilient, horizontal, flat, massive and rigid surface in
conformity with the requirements of 6.1.5.3.4, in such a manner as to ensure that the point of impact is
that part of the base of the IBC considered to be the most vulnerable. IBCs of 0.45 m3 or less capacity
shall also be dropped:
(a) Metal IBCs: on the most vulnerable part other than the part of the base tested in the first drop;
(b) Flexible IBCs: on the most vulnerable side;
(c) Rigid plastics, composite, fibreboard and wooden IBCs: flat on a side, flat on the top and on a
corner.
The same or different IBCs may be used for each drop.

substance having essentially the same physical characteristics:

 

For liquids if the test is performed with water:

 

(a) Where the substances to be carried have a relative density not exceeding 1.2:

(b) Where the substances to be carried have a relative density exceeding 1.2, the drop heights shall be calculated on the basis of the relative density (d) of the substance to be carried rounded up to the first decimal as follows:

Criteria for passing the test(s):
(a) Metal IBCs: no loss of contents;
(b) Flexible IBCs: no loss of contents. A slight discharge, e.g. from closures or stitch holes, upon
impact shall not be considered to be a failure of the IBC provided that no further leakage
occurs after the IBC has been raised clear of the ground;
(c) Rigid plastics, composite, fibreboard and wooden IBCs: no loss of contents. A slight discharge
from a closure upon impact shall not be considered to be a failure of the IBC provided that no
further leakage occurs;
(d) All IBCs: no damage which renders the IBC unsafe to be carried for salvage or for disposal,
and no loss of contents. In addition, the IBC shall be capable of being lifted by an appropriate
means until clear of the floor for five minutes.
NOTE: The criteria in (d) apply to design types for IBCs manufactured as from
1 January 2011.

Tear test

Applicability

For all types of flexible IBCs, as a design type test.

Preparation of the IBC for test

The IBC shall be filled to not less than 95% of its capacity and to its maximum permissible gross
mass, the contents being evenly distributed.

Method of testing

Once the IBC is placed on the ground, a 100 mm knife score, completely penetrating the wall of a
wide face, is made at a 45° angle to the principal axis of the IBC, halfway between the bottom surface
and the top level of the contents. The IBC shall then be subjected to a uniformly distributed
superimposed load equivalent to twice the maximum permissible gross mass. The load shall be
applied for at least five minutes. An IBC which is designed to be lifted from the top or the side shall
then, after removal of the superimposed load, be lifted clear of the floor and maintained in that
position for a period of five minutes.

Criteria for passing the test

The cut shall not propagate more than 25% of its original length.

Topple test

Applicability

For all types of flexible IBC, as a design type test.

Preparation of the IBC for test

The IBC shall be filled to not less than 95% of its capacity and to its maximum permissible gross
mass, the contents being evenly distributed.

Method of testing

The IBC shall be caused to topple on to any part of its top on to a rigid, non-resilient, smooth, flat and
horizontal surface.
