3.1.10 Except for air-transport, rescue containers shall be tested and marked in

accordance with regulations which are applicable to intended solid transport or Class II

packaging containers of inner containers, except for following cases.

a) Test substance used in the test shall be water; and water in the container shall not

be less than 98% of maximum capacity. In order to meet mass requirements of total

packages, additional-weight is allowed, such as. lead granular bag, as long as it does

not affect test results. During drop test, dropping height can be changed based on

4.1.4b);

b) The container has passed leakage test of 30kPa, and test results are shown in the

test report required 4.5;

c) The container shall be marked with "T" as specified in 5.1.4 of SN/T 0370.1-2009.

3.2 Sampling

3.2.1 For mass-produced packaging containers with same design-model, based on factory

inspection, randomly select samples from work site. For containers of which the quality

level is prone to fluctuating, samples shall include the products of which the safety strength

is the weakest.

3.2.2 Randomly selected samples shall have relevant marks and batch number of UN. The

number of samples shall meet requirements of normal inspection items, and one retention

sample is added and preserved for half a year at least.

3.2.3 If design-model changes, it is necessary to re-select samples based on 3.2.1.

3.3 Inspection preparation of containers

3.3.1 For prepared containers used for transport, including inner containers used by

composition container, conduct test in accordance with requirements of this Part. Liquid in

the inner container, single container or container outside bag shall not be less than 98% of

maximum capacity, and liquid shall not be less than 95% of maximum capacity. For

composition container, if inner container is transported with liquid and solid, it is necessary

to conduct tests for liquid contents and solid contents. Contents used during test may not

necessarily be the substances or articles of actual transport, unless such arrangement will

cause test results invalid. For solid, when using another substance to replace, the

substance shall have the same physical properties with substance to be transported (such

as. mass, particle size, etc.). In order to meet mass requirements of total packages,

additional-weight is allowed, such as. lead granular bag, as long as it does not affect test

results.

3.3.2 When drop test is conducted for container filled with liquid, if other substances are

used for replacement, the substance shall have relative density and relative viscosity

similar to the substance to be transported. Water can also be used for drop test of liquid

under conditions of 4.1.4.

3.3.3 Paper and fiberboard containers shall be placed for 24h in the environment of

controlled temperature and relative humidity. There are three methods as follows, one of

them shall be selected. 23°C± 2°C and 50% ± 2% of relative humidity is the best

environment. Another two methods. 20°C± 2°C and relative humidity (65% ± 2%), or 27°C±

2°C and relative humidity (65% ± 2%).

Note. Average value shall be within these limited values. Short fluctuation and measurement

limit might change ± 5% of relative humidity measurement, but might not greatly affect re-

inspection of test results.

3.3.4 For first-time used plastic drum (tank), plastic composite containers and coated

container, it is necessary to directly fill out dangerous goods to be transported and store

them for over 6 months in accordance with GB/T 22410 to conduct compatibility test.

3.4 Inspection items

For packaging inspection items of various common export dangerous goods, refer to

Annex A. In addition, for road and railway transport, conduct permeability test for plastic

drum, plastic tank and composite containers (plastic) (except for 6HA1) which is filled with

flammable liquid with flash spot of not more than 61°C.

4.1 Drop test

4.1.1 Number of test samples and dropping direction

For number of test samples for all design-models and dropping direction, refer to Table 1.

Except for dropping of plane landing, center of gravity shall be located above vertical

direction of impact point. If certain dropping tests might not be conducted in one direction,

it is necessary to test the weakest part.
