Excepted quantities of dangerous goods of certain classes, other than articles, meeting the provisions
of this Chapter are not subject to any other provisions of ADR except for:
(a) The training requirements in Chapter 1.3;
(b) The classification procedures and packing group criteria in Part 2;
(c) The packaging requirements of 4.1.1.1, 4.1.1.2, 4.1.1.4 and 4.1.1.6.
NOTE: In the case of radioactive material, the requirements for radioactive material in excepted
packages in 1.7.1.5 apply.

Dangerous goods which may be carried as excepted quantities in accordance with the provisions of this Chapter are shown in column (7b) of Table A of Chapter 3.2 list by means of an alphanumeric code as follows:

For gases, the volume indicated for inner packagings refers to the water capacity of the inner receptacle and the volume indicated for outer packagings refers to the combined water capacity of all inner packagings within a single outer packaging.

Where dangerous goods in excepted quantities for which different codes are assigned are packaged together the total quantity per outer packaging shall be limited to that corresponding to the most restrictive code.

Excepted quantities of dangerous goods assigned to codes E1, E2, E4 and E5 with a maximum net
quantity of dangerous goods per inner packaging limited to 1 ml for liquids and gases and 1 g for
solids and a maximum net quantity of dangerous goods per outer packaging which does not exceed
100 g for solids or 100 ml for liquids and gases are only subject to:
(a) The provisions of 3.5.2, except that an intermediate packaging is not required if the inner
packagings are securely packed in an outer packaging with cushioning material in such a way
that, under normal conditions of carriage, they cannot break, be punctured, or leak their
contents; and for liquids, the outer packaging contains sufficient absorbent material to absorb
the entire contents of the inner packagings; and
(b) The provisions of 3.5.3.

The complete package as prepared for carriage, with inner packagings filled to not less than 95% of their capacity for solids or 98% for liquids, shall be capable of withstanding, as demonstrated by testing which is appropriately documented, without breakage or leakage of any inner packaging and without significant reduction in effectiveness:

(a) Drops onto a rigid, non-resilient flat and horizontal surface from a height of 1.8 m:

(i) Where the sample is in the shape of a box, it shall be dropped in each of the following orientations:

- flat on the base;

- flat on the top;

- flat on the longest side;

- flat on the shortest side;

- on a corner;

(ii) Where the sample is in the shape of a drum, it shall be dropped in each of the following orientations:

- diagonally on the top chime, with the centre of gravity directly above the point of impact;

- diagonally on the base chime;

- flat on the side;

NOTE: Each of the above drops may be performed on different but identical packages.

(b) A force applied to the top surface for a duration of 24 hours, equivalent to the total weight of identical packages if stacked to a height of 3 m (including the sample).

For the purposes of testing, the substances to be carried in the packaging may be replaced by other substances except where this would invalidate the results of the tests. For solids, when another substance is used, it must have the same physical characteristics (mass, grain size, etc.) as the substance to be carried. In the drop tests for liquids, when another substance is used, its relative density (specific gravity) and viscosity should be similar to those of the substance to be carried.

Packages containing excepted quantities of dangerous goods prepared in accordance with this Chapter  shall be durably and legibly marked with the mark shown in 3.5.4.2. The first or only label number indicated in column (5) of Table A of Chapter 3.2 for each of the dangerous goods contained in the package shall be shown in the mark. Where the name of the consignor or consignee is not shown elsewhere on the package this information shall be included within the mark.
