USE OF FIXED TANKS (TANK-VEHICLES), DEMOUNTABLE TANKS, TANK-CONTAINERS AND TANK SWAP BODIES WITH SHELLS MADE OF METALLIC MATERIALS, AND BATTERY-VEHICLES AND MULTIPLE-ELEMENT GAS CONTAINERS (MEGCs)
NOTE: For portable tanks and UN multiple-element gas containers (MEGCs) see Chapter 4.2; for fibrereinforced
plastics tanks, see Chapter 4.4; for vacuum operated waste tanks, see Chapter 4.5.
Provisions which take up the whole width of the page apply both to fixed tanks (tank-vehicles),
demountable tanks and battery-vehicles, and to tank-containers, tank swap bodies and MEGCs.
Provisions contained in a single column apply only to:
- fixed tanks (tank-vehicles), demountable tanks and battery-vehicles (left-hand column);
- tank-containers, tank swap bodies and MEGCs (right-hand column).
These provisions apply to:
fixed tanks (tank-vehicles), demountable tanks
tank-containers, tank swap bodies and MEGCs
used for the carriage of gaseous, liquid, powdery or granular substances.
Section 4.3.2 lists the provisions applicable to fixed tanks (tank-vehicles), demountable tanks, tankcontainers
and tank swap bodies, intended for the carriage of substances of all classes, and to batteryvehicles
and MEGCs intended for the carriage of gases of Class 2. Sections 4.3.3 and 4.3.4 contain
special provisions adding to or amending the provisions of Section 4.3.2.
For requirements concerning the construction, equipment, type approval, tests and marking, see
For transitional measures concerning the application of this Chapter, see:
1.6.3. | 1.6.4.
Provisions applicable to all classes
A substance subject to ADR may be carried in fixed tanks (tank-vehicles), demountable tanks, batteryvehicles,
tank-containers, tank swap bodies and MEGCs only when provision is made for a tank code
according to 126.96.36.199.1 and 188.8.131.52.1 in Column (12) of Table A in Chapter 3.2.
The required type of tank, battery-vehicle and MEGC is given in code form in Column (12) of Table
A in Chapter 3.2. The explanations for reading the four parts of the code are given in 184.108.40.206.1 (when
the substance to be carried belongs to Class 2) and in 220.127.116.11.1 (when the substance to be carried
belongs to Classes 1 and 3 to 9)1.
The required type according to 18.104.22.168.2 corresponds to the least stringent construction requirements
which are acceptable for the dangerous substance in question unless otherwise prescribed in this
Chapter or in Chapter 6.8. It is possible to use tanks corresponding to codes prescribing a higher
minimum calculation pressure, or more stringent requirements for filling or discharge openings or for
safety valves/devices (see 22.214.171.124.1 for Class 2 and 126.96.36.199.1 for Classes 3 to 9).
1 An exception is made for tanks intended for the carriage of substances of classes 1, 5.2 or 7 (see 188.8.131.52.3).
For certain substances, tanks, battery-vehicles or MEGCs are subject to additional provisions which
are included as special provisions in Column (13) of Table A in Chapter 3.2.
Tanks, battery-vehicles and MEGCs shall not be loaded with any dangerous substances other than
those for the carriage of which they have been approved according to 184.108.40.206.1 and which, in contact
with the materials of the shell, gaskets, equipment and protective linings, are not liable to react
dangerously with them (see "dangerous reaction" in 1.2.1), to form dangerous products or appreciably
to weaken these materials2.
Foodstuffs shall not be carried in tanks used for dangerous substances unless the necessary steps have
been taken to prevent any harm to public health.
