Dangerous Goods by Road
Column (8) of Table A of Chapter 3.2 shows for each article or substance the packing instruction(s)
that shall be used. Columns (9a) and (9b) indicate the special packing provisions and the mixed
packing provisions (see 4.1.10) applicable to specific substances or articles.
Each packing instruction shows, where applicable, the acceptable single and combination packagings.
For combination packagings, the acceptable outer packagings, inner packagings and when applicable
the maximum quantity permitted in each inner or outer packaging, are shown. Maximum net mass and
maximum capacity are as defined in 1.2.1.
The following packagings shall not be used when the substances being carried are liable to become
liquid during carriage:
Packagings
Drums: 1D and 1G
Boxes: 4A, 4B, 4N, 4C1, 4C2, 4D, 4F, 4G, 4H1 and 4H2
Bags: 5L1, 5L2, 5L3, 5H1, 5H2, 5H3, 5H4, 5M1 and 5M2
Composite packagings: 6HC, 6HD2, 6HG1, 6HG2, 6HD1, 6PC, 6PD1, 6PD2, 6PG1, 6PG2
and 6PH1
Large packagings
Flexible plastics: 51H (outer packaging)
IBCs
For substances of packing group I: All types of IBC
For substances of packing groups II and III:
Wooden: 11C, 11D and 11F
Fibreboard: 11G
Flexible: 13H1, 13H2, 13H3, 13H4, 13H5, 13L1, 13L2, 13L3, 13L4,
13M1 and 13M2
Composite: 11HZ2 and 21HZ2
For the purposes of this paragraph, substances and mixtures of substances having a melting point
equal to or less than 45 °C shall be treated as solids liable to become liquid during carriage.
Where the packing instructions in this Chapter authorize the use of a particular type of packaging (e.g.
4G; 1A2), packagings bearing the same packaging identification code followed by the letters "V", "U"
or "W" marked in accordance with the requirements of Part 6 (e.g. 4GV, 4GU or 4GW; 1A2V, 1A2U
or 1A2W) may also be used under the same conditions and limitations applicable to the use of that
type of packaging according to the relevant packing instructions. For example, a combination
packaging marked with the packaging code "4GV" may be used whenever a combination packaging
marked "4G" is authorized, provided the requirements in the relevant packing instruction regarding
types of inner packagings and quantity limitations are respected.
Pressure receptacles for liquids and solids
Unless otherwise indicated in ADR, pressure receptacles conforming to:
(a) the applicable requirements of Chapter 6.2; or
(b) the national or international standards on the design, construction, testing, manufacturing and
inspection, as applied by the country in which the pressure receptacles are manufactured,
provided that the provisions of 4.1.3.6 are met, and that, for metallic cylinders, tubes, pressure
drums, bundles of cylinders and salvage pressure receptacles, the construction is such that the
minimum burst ratio (burst pressure divided by test pressure) is:
(i) 1.50 for refillable pressure receptacles;
(ii) 2.00 for non-refillable pressure receptacles,
are authorized for the carriage of any liquid or solid substance other than explosives, thermally
unstable substances, organic peroxides, self-reactive substances, substances where significant pressure
may develop by evolution of chemical reaction and radioactive material (unless permitted in 4.1.9).
This sub-section is not applicable to the substances mentioned in 4.1.4.1, packing instruction P200,
table 3.
Every design type of pressure receptacle shall be approved by the competent authority of the country
of manufacture or as indicated in Chapter 6.2.
Unless otherwise indicated, pressure receptacles having a minimum test pressure of 0.6 MPa shall be
used.
Unless otherwise indicated, pressure receptacles may be provided with an emergency pressure relief
device designed to avoid bursting in case of overfill or fire accidents.
Pressure receptacle valves shall be designed and constructed in such a way that they are inherently
able to withstand damage without release of the contents or shall be protected from damage which
could cause inadvertent release of the contents of the pressure receptacle, by one of the methods as
given in 4.1.6.8 (a) to (e).
The level of filling shall not exceed 95% of the capacity of the pressure receptacle at 50 °C. Sufficient
ullage (outage) shall be left to ensure that the pressure receptacle will not be liquid full at a
temperature of 55 °C.
Unless otherwise indicated pressure receptacles shall be subjected to a periodic inspection and test
every 5 years. The periodic inspection shall include an external examination, an internal examination
or alternative method as approved by the competent authority, a pressure test or equivalent effective
non-destructive testing with the agreement of the competent authority including an inspection of all
accessories (e.g. tightness of valves, emergency relief valves or fusible elements). Pressure
receptacles shall not be filled after they become due for periodic inspection and test but may be
carried after the expiry of the time limit. Pressure receptacle repairs shall meet the requirements
of 4.1.6.11.
Prior to filling, the packer shall perform an inspection of the pressure receptacle and ensure that the
pressure receptacle is authorized for the substances to be carried and that the requirements of ADR
have been met. Shut-off valves shall be closed after filling and remain closed during carriage. The
consignor shall verify that the closures and equipment are not leaking.
Refillable pressure receptacles shall not be filled with a substance different from that previously
contained unless the necessary operations for change of service have been performed.
Marking of pressure receptacles for liquids and solids according to 4.1.3.6 (not conforming to the
requirements of Chapter 6.2) shall be in accordance with the requirements of the competent authority
of the country of manufacturing.
Packagings or IBCs not specifically authorized in the applicable packing instruction shall not be used
for the carriage of a substance or article unless specifically allowed under a temporary derogation
agreed between Contracting Parties in accordance with 1.5.1.
