After the specimen, prototype or sample has been subjected to the tests, appropriate methods of
assessment shall be used to assure that the requirements for the test procedures have been fulfilled in
compliance with the performance and acceptance standards prescribed in 184.108.40.206.3.1.3, 220.127.116.11.3.1.4,
18.104.22.168.3.3.1, 22.214.171.124.3.3.2, 126.96.36.199.3.4.1, 188.8.131.52.3.4.2, and 6.4.2 to 6.4.11.
All specimens shall be inspected before testing in order to identify and record faults or damage
including the following:
(a) Divergence from the design;
(b) Defects in manufacture;
(c) Corrosion or other deterioration; and
(d) Distortion of features.
The containment system of the package shall be clearly specified. The external features of the
specimen shall be clearly identified so that reference may be made simply and clearly to any part
Testing the integrity of the containment system and shielding and evaluating criticality safety
After each of the applicable tests specified in 6.4.15 to 6.4.21:
(a) Faults and damage shall be identified and recorded;
(b) It shall be determined whether the integrity of the containment system and shielding has been
retained to the extent required in 6.4.2 to 6.4.11 for the package under test; and
(c) For packages containing fissile material, it shall be determined whether the assumptions and
conditions used in the assessments required by 184.108.40.206 to 220.127.116.11 for one or more packages
Target for drop tests
The target for the drop tests specified in 18.104.22.168.3.3.5 (a), 22.214.171.124, 6.4.16 (a), 126.96.36.199 and 188.8.131.52
shall be a flat, horizontal surface of such a character that any increase in its resistance to displacement
or deformation upon impact by the specimen would not significantly increase the damage to the
Tests for demonstrating ability to withstand normal conditions of carriage
The tests are: the water spray test, the free drop test, the stacking test and the penetration test.
Specimens of the package shall be subjected to the free drop test, the stacking test and the penetration
test, preceded in each case by the water spray test. One specimen may be used for all the tests,
provided that the requirements of 184.108.40.206 are fulfilled.
The time interval between the conclusion of the water spray test and the succeeding test shall be such
that the water has soaked in to the maximum extent, without appreciable drying of the exterior of the
specimen. In the absence of any evidence to the contrary, this interval shall be taken to be two hours if
the water spray is applied from four directions simultaneously. No time interval shall elapse, however,
if the water spray is applied from each of the four directions consecutively.
Water spray test: The specimen shall be subjected to a water spray test that simulates exposure to
rainfall of approximately 5 cm per hour for at least one hour.
Free drop test: The specimen shall drop onto the target so as to suffer maximum damage in respect
the safety features to be tested.
(a) The height of drop measured from the lowest point of the specimen to the upper surface of the
target shall be not less than the distance specified in Table 220.127.116.11 for the applicable mass.
The target shall be as defined in 6.4.14;
(b) For rectangular fibreboard or wood packages not exceeding a mass of 50 kg, a separate
specimen shall be subjected to a free drop onto each corner from a height of 0.3 m;
(c) For cylindrical fibreboard packages not exceeding a mass of 100 kg, a separate specimen
shall be subjected to a free drop onto each of the quarters of each rim from a height of 0.3 m.

Stacking test: Unless the shape of the packaging effectively prevents stacking, the specimen shall be
subjected, for a period of 24 h, to a compressive load equal to the greater of the following:
(a) The equivalent of 5 times the maximum weight of the package; and
(b) The equivalent of 13 kPa multiplied by the vertically projected area of the package.
The load shall be applied uniformly to two opposite sides of the specimen, one of which shall be the
base on which the package would typically rest.
Penetration test: The specimen shall be placed on a rigid, flat, horizontal surface which will not move
significantly while the test is being carried out.
(a) A bar of 3.2 cm in diameter with a hemispherical end and a mass of 6 kg shall be dropped and
directed to fall, with its longitudinal axis vertical, onto the centre of the weakest part of the
specimen, so that, if it penetrates sufficiently far, it will hit the containment system. The bar
shall not be significantly deformed by the test performance;
(b) The height of drop of the bar measured from its lower end to the intended point of impact on
the upper surface of the specimen shall be 1 m.
Additional tests for Type A packages designed for liquids and gases
A specimen or separate specimens shall be subjected to each of the following tests unless it can be
demonstrated that one test is more severe for the specimen in question than the other, in which case
one specimen shall be subjected to the more severe test.
(a) Free drop test: The specimen shall drop onto the target so as to suffer the maximum damage in
respect of containment. The height of the drop measured from the lowest part of the specimen
to the upper surface of the target shall be 9 m. The target shall be as defined in 6.4.14;
(b) Penetration test: The specimen shall be subjected to the test specified in 22.214.171.124 except that the
height of drop shall be increased to 1.7 m from the 1 m specified in 126.96.36.199 (b).
Tests for demonstrating ability to withstand accident conditions in carriage
The specimen shall be subjected to the cumulative effects of the tests specified in 188.8.131.52
and 184.108.40.206, in that order. Following these tests, either this specimen or a separate specimen shall be
subjected to the effect(s) of the water immersion test(s) as specified in 220.127.116.11 and, if applicable,
Mechanical test: The mechanical test consists of three different drop tests. Each specimen shall be
subjected to the applicable drops as specified in 18.104.22.168 or 22.214.171.124. The order in which the
specimen is subjected to the drops shall be such that, on completion of the mechanical test, the
specimen shall have suffered such damage as will lead to the maximum damage in the thermal test
(a) For drop I, the specimen shall drop onto the target so as to suffer the maximum damage, and
the height of the drop measured from the lowest point of the specimen to the upper surface of
the target shall be 9 m. The target shall be as defined in 6.4.14;
(b) For drop II, the specimen shall drop onto a bar rigidly mounted perpendicularly on the
target so as to suffer the maximum damage. The height of the drop measured from the intended point
of impact of the specimen to the upper surface of the bar shall be 1 m. The bar shall be of solid
mild steel of circular section, (15.0 cm ± 0.5 cm) in diameter and 20 cm long unless a longer bar
would cause greater damage, in which case a bar of sufficient length to cause maximum damage shall
be used. The upper end of the bar shall be flat and horizontal with its edge rounded off to a
radius of not more than 6 mm. The target on which the bar is mounted shall be as described in
(c) For drop III, the specimen shall be subjected to a dynamic crush test by positioning the
specimen on the target so as to suffer maximum damage by the drop of a 500 kg mass from 9 m
onto the specimen. The mass shall consist of a solid mild steel plate 1 m by 1 m and shall fall in
a horizontal attitude. The lower face of the steel plate shall have its edges and corners rounded
off to a radius of not more than 6 mm. The height of the drop shall be measured from the underside
of the plate to the highest point of the specimen. The target on which the specimen rests shall be
as defined in 6.4.14.
