Tank code |
1 |
Types of tank |
L = tank for substances in the liquid state (liquids or solids handed over for carriage in the molten state);
S = tank for substances in the solid state (powdery or granular). |
2 |
Calculation pressure |
G = minimum calculation pressure according to the general requirements of 6.8.2.1.14; or
1.5; 2.65; 4; 10; 15 or 21= minimum calculation pressure in bar (see 6.8.2.1.14). |
3 |
Openings (see 6.8.2.2.2) |
A = tank with bottom-filling or bottom-discharge openings with 2 closures; |
B = tank with bottom-filling or bottom-discharge openings with 3 closures;
C = tank with top-filling and discharge openings with only cleaning openings below the surface of the liquid;
D = tank with top-filling and discharge openings with no openings below the surface of the liquid. |
||
4 |
Safety valves/devices |
V = tank with a breather device, according to 6.8.2.2.6, but no device protecting against the propagation of a flame; or non-explosion pressure shock resistant tank ;
F = tank with a breather device, according to 6.8.2.2.6, fitted with a device protecting against the propagation of a flame; or explosion pressure shock resistant tank ;
N = tank without a breather device according to 6.8.2.2.6 and not hermetically closed; |
B = tank with bottom-filling or bottom-discharge openings with 3 closures;
C = tank with top-filling and discharge openings with only cleaning openings below the surface of the liquid;
D = tank with top-filling and discharge openings with no openings below the surface of the liquid. |

Hierarchy of tanks
Tanks with tank codes different from those indicated in this table or in Table A of Chapter 3.2 may also be used provided that any element (number or letter) of parts 1 to 4 of these tank codes correspond to a level of safety at least equivalent to the corresponding element of the tank code indicated in Table A of Chapter 3.2, according to the following increasing order:
Part 1: Types of tanks S L
Part 2: Calculation pressure
G 1.5 2.65 4 10 15 21 bar
Part 3: Openings A B C D
Part 4: Safety valves/devices V F N H
For example:
A tank with the tank code L10CN is authorized for the carriage of a substance to which the tank code L4BN has been assigned;
A tank with the tank code L4BN is authorized for the carriage of a substance to which the tank code SGAN has been assigned.
E: The hierarchy does not take account of any special provisions for each entry (see 4.3.5 and
.8.4).
