General

The requirements of this Chapter do not apply to:
- packagings for Class 2, except large packagings for articles, including aerosols;
- packagings for Class 6.2, except large packagings for clinical waste of UN No. 3291;
- Class 7 packages containing radioactive material.

Large packagings shall be manufactured, tested and remanufactured under a quality assurance
programme which satisfies the competent authority in order to ensure that each manufactured or
remanufactured large packaging meets the requirements of this Chapter.
NOTE: ISO 16106:2006 "Packaging – Transport packages for dangerous goods – Dangerous
goods packagings, intermediate bulk containers (IBCs) and large packagings – Guidelines for the
application of ISO 9001" provides acceptable guidance on procedures which may be followed.

The specific requirements for large packagings in 6.6.4 are based on large packagings currently used.
In order to take into account progress in science and technology, there is no objection to the use of
large packagings having specifications different from those in 6.6.4 provided they are equally
effective, acceptable to the competent authority and able successfully to withstand the tests described
in 6.6.5. Methods of testing other than those described in ADR are acceptable provided they are
equivalent and are recognized by the competent authority.

Manufacturers and subsequent distributors of packagings shall provide information regarding
procedures to be followed and a description of the types and dimensions of closures (including
required gaskets) and any other components needed to ensure that packages as presented for carriage
are capable of passing the applicable performance tests of this Chapter.

Code for designating types of large packagings

The code used for large packagings consist of:
(a) Two Arabic numerals:
50 for rigid large packagings; or
51 for flexible large packagings; and
(b) A capital letter in Latin character indicating the nature of the material, e.g. wood, steel etc. The
capital letters used shall be those shown in 6.1.2.6.

The letters "T" or "W" may follow the Large Packaging code. The letter "T" signifies a large salvage
packaging conforming to the requirements of 6.6.5.1.9. The letter "W" signifies that the large
packaging, although of the same type indicated by the code, is manufactured to a specification
different from those in 6.6.4 and is considered equivalent in accordance with the requirements
in 6.6.1.3.

Marking

Primary marking

Each large packaging manufactured and intended for use in accordance with the provisions of ADR
shall bear marks which are durable, legible and placed in a location so as to be readily visible. 
Letters, numerals and symbols shall be at least 12 mm high and shall show:
 
 
(a)        The United Nations packaging symbol                                              ;
 
 
This symbol shall not be used for any purpose other than certifying that a packaging, a flexible 
bulk container, a portable tank or a MEGC complies with the relevant  requirements  in  Chapter 
6.1, 6.2, 6.3, 6.5, 6.6, 6.7 or 6.11. For metal large packagings on which the marks are stamped or 
embossed, the capital letters "UN" may be applied instead of the symbol;
 
(b) The number "50" designating a large rigid packaging or "51" for flexible large packagings, 
followed by the material type in accordance with 6.5.1.4.1 (b);
 
(c)      A capital letter designating the packing group(s) for which the design type has been 
approved:
X for packing groups I, II and III Y for packing groups II and III  Z for packing group III only;
(d)      The month and year (last two digits) of manufacture;
 
(e) The State authorizing the allocation of the mark; indicated by the distinguishing sign used on 
vehicles in international road traffic1;
(f) The name or symbol of the manufacturer and other identification of the large packagings as 
specified by the competent authority;
 
(g)    The stacking test load in kg. For large packagings not designed for stacking the figure "0" 
shall be shown;
 
(h)      The maximum permissible gross mass in kilograms.
 
The primary mark required above shall be applied in the sequence of the sub-paragraphs.
 
Each mark applied in accordance with (a) to (h) shall be clearly separated, e.g. by a slash or 
space, so as to be easily identifiable.
1                 Distinguishing sign of the State of registration used on motor vehicles and 
trailers in international road traffic, in accordance with the Geneva Convention on Road Traffic of 
1949 or the Vienna Convention on Road Traffic of
1968.
 

Examples of marking

The maximum permitted stacking load applicable when the large packaging is in use shall be
displayed on a symbol as shown in Figure 6.6.3.3.1 or Figure 6.6.3.3.2. The symbol shall be durable
and clearly visible.
 
 
 
The minimum dimensions shall be 100 mm x 100 mm. The letters and numbers indicating the mass
shall be at least 12 mm high. The area within the printer’s marks indicated by the dimensional arrows
shall be square. Where dimensions are not specified, all features shall be in approximate proportion to
those shown. The mass marked above the symbol shall not exceed the load imposed during the design
type test (see 6.6.5.3.3.4) divided by 1.8.

 

Specific requirements for large packagings

Specific requirements for metal large packagings

50A steel
50B aluminium
50N metal (other than steel or aluminium)

The large packaging shall be made of suitable ductile metal in which the weldability has been fully
demonstrated. Welds shall be skilfully made and afford complete safety. Low-temperature
performance shall be taken into account when appropriate.
