Mark for packages containing limited quantities
 
The mark shall be readily visible, legible and able to withstand open weather exposure without a
substantial reduction in effectiveness.
The mark shall be in the form of a square set at an angle of 45° (diamond-shaped). The top and
bottom portions and the surrounding line shall be black. The centre area shall be white or a suitable
contrasting background. The minimum dimensions shall be 100 mm x 100 mm and the minimum
width of the line forming the diamond shall be 2 mm. Where dimensions are not specified, all features
shall be in approximate proportion to those shown.

 

If the size of the package so requires, the minimum outer dimensions shown in Figure 3.4.7.1 may be
reduced to be not less than 50 mm x 50 mm provided the mark remains clearly visible. The minimum
width of the line forming the diamond may be reduced to a minimum of 1 mm.

Use of overpacks

For an overpack containing dangerous goods packed in limited quantities, the following applies:
Unless the marks representative of all dangerous goods in an overpack are visible, the overpack shall
be:
– marked with the word “OVERPACK”. The lettering of the “OVERPACK” mark shall be at
least 12 mm high. The mark shall be in an official language of the country of origin and also, if
that language is not English, French or German, in English, French or German, unless
agreements, if any, concluded between the countries concerned in the transport operation
provide otherwise; and
– marked with the marks required by this Chapter.
Except for air transport, the other provisions of 5.1.2.1 apply only if other dangerous goods which are
not packed in limited quantities are contained in the overpack and only in relation to these other
dangerous goods.

In advance of carriage, consignors of dangerous goods packed in limited quantities shall inform the
carrier in a traceable form of the total gross mass of such goods to be consigned.

(a) Transport units with a maximum mass exceeding 12 tonnes carrying dangerous goods packed
in limited quantities shall be marked in accordance with 3.4.15 at the front and at the rear
except when the transport unit contains other dangerous goods for which orange-coloured plate
marking in accordance with 5.3.2 is required. In this latter case, the transport unit may display
the required orange-coloured plate marking only, or both the orange-coloured plate marking in
accordance with 5.3.2 and the marks in accordance with 3.4.15.
(b) Containers carrying dangerous goods packed in limited quantities, on transport units with a
maximum mass exceeding 12 tonnes, shall be marked in accordance with 3.4.15 on all four
sides except when the container contains other dangerous goods for which placarding in
accordance with 5.3.1 is required. In this latter case, the container may display the required
placards only, or both the placards in accordance with 5.3.1 and the marks in accordance with
3.4.15.
The carrying transport unit need not be marked, except when the marks affixed to the
containers are not visible from outside this carrying transport unit. In this latter case, the same
marks shall be affixed at the front and at the rear of the transport unit.

The marks specified in 3.4.13 may be dispensed with, if the total gross mass of the packages
containing dangerous goods packed in limited quantities carried does not exceed 8 tonnes per
transport unit.

The marks specified in 3.4.13 shall be the same as the one required in 3.4.7, except that their
minimum dimensions shall be 250 mm × 250 mm. These marks shall be removed or covered if no
dangerous goods in limited quantities are carried.
