Dangerous Goods by Road
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
large packaging.
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.
Test requirements for large packagings
Performance and frequency of test
The design type of each large packaging shall be tested as provided in 6.6.5.3 in accordance with
procedures established by the competent authority allowing the allocation of the mark and shall be
approved by this competent authority.
Each large packaging design type shall successfully pass the tests prescribed in this Chapter before
being used. A large packaging design type is defined by the design, size, material and thickness,
manner of construction and packing, but may include various surface treatments. It also includes large
packagings which differ from the design type only in their lesser design height.
Tests shall be repeated on production samples at intervals established by the competent authority. For
such tests on fibreboard large packagings, preparation at ambient conditions is considered equivalent
to the provisions of 6.6.5.2.4.
Tests shall also be repeated after each modification which alters the design, material or manner of
construction of large packagings.
The competent authority may permit the selective testing of large packagings that differ only in minor
respects from a tested type, e.g. smaller sizes of inner packagings or inner packagings of lower net
mass; and large packagings which are produced with small reductions in external dimension(s).
(Reserved)
NOTE: For the conditions for assembling different inner packagings in a large packaging and
permissible variations in inner packagings, see 4.1.1.5.1.
The competent authority may at any time require proof, by tests in accordance with this section, that
serially-produced large packagings meet the requirements of the design type tests.
Provided the validity of the test results is not affected and with the approval of the competent
authority, several tests may be made on one sample.
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.
