Large salvage packagings
packing group II large packagings intended for the carriage of solids or inner packagings, except as
follows:
(a) The test substance used in performing the tests shall be water, and the large salvage packagings
shall be filled to not less than 98% of their maximum capacity. It is permissible to use additives,
such as bags of lead shot, to achieve the requisite total package mass so long as they are placed
so that the test results are not affected. Alternatively, in performing the drop test, the drop height
may be varied in accordance with 6.6.5.3.4.4.2 (b);
(b) Large salvage packagings shall, in addition, have been successfully subjected to the
leakproofness test at 30 kPa, with the results of this test reflected in the test report required by
6.6.5.4; and
(c) Large salvage packagings shall be marked with the letter "T" as described in 6.6.2.2.
Preparation for testing
Tests shall be carried out on large packagings prepared as for carriage including the inner packagings
or articles used. Inner packagings shall be filled to not less than 98% of their maximum capacity for
liquids or 95% for solids. For large packagings where the inner packagings are designed to carry
liquids and solids, separate testing is required for both liquid and solid contents. The substances in the
inner packagings or the articles to be carried in the large packagings may be replaced by other
material or articles except where this would invalidate the results of the tests. When other inner
packagings or articles are used they shall have the same physical characteristics (mass, etc) as the
inner packagings or articles to be carried. It is permissible to use additives, such as bags of lead shot,
to achieve the requisite total package mass, so long as they are placed so that the test results are not
affected.
In the drop tests for liquids, when another substance is used, it shall be of similar relative density and
viscosity to those of the substance being carried. Water may also be used for the liquid drop test under
the conditions in 6.6.5.3.4.4.
Large packagings made of plastics materials and large packagings containing inner packagings of
plastic materials - other than bags intended to contain solids or articles - shall be drop tested when the
temperature of the test sample and its contents has been reduced to -18 °C or lower. This conditioning
may be disregarded if the materials in question are of sufficient ductility and tensile strength at low
temperatures. Where test sample are prepared in this way, the conditioning in 6.6.5.2.4 may be
waived. Test liquids shall be kept in the liquid state by the addition of anti-freeze if necessary.
Large packagings of fibreboard shall be conditioned for at least 24 hours in an atmosphere having a
controlled temperature and relative humidity (r.h.). There are three options, one of which shall be
chosen.
The preferred atmosphere is 23 °C ± 2 °C and 50% ± 2% r.h. The two other options are: 20 °C ± 2 °C
and 65% ± 2% r.h.; or 27 °C ± 2 °C and 65% ± 2% r.h.
NOTE: Average values shall fall within these limits. Short term fluctuations and measurement
limitations may cause individual measurements to vary by up to ± 5% relative humidity without
significant impairment of test reproducibility.
Test requirements
Bottom lift test
Applicability
For all types of large packagings which are fitted with means of lifting from the base, as a design type
test.
Preparation of large packaging for test
The large packaging shall be loaded to 1.25 times its maximum permissible gross mass, the load being
evenly distributed.
Method of testing
The large packaging shall be raised and lowered twice by a lift truck with the forks centrally
positioned and spaced at three quarters of the dimension of the side of entry (unless the points of entry
are fixed). The forks shall penetrate to three quarters of the direction of entry. The test shall be
repeated from each possible direction of entry.
Criteria for passing the test
No permanent deformation which renders the large packaging unsafe for carriage and no loss of
contents.
Top lift test
Applicability
For types of large packagings which are intended to be lifted from the top and fitted with means of
lifting, as a design type test.
Preparation of large packaging for test
The large packaging shall be loaded to twice its maximum permissible gross mass. A flexible large
packaging shall be loaded to six times its maximum permissible gross mass, the load being evenly
distributed.
