ADR tank code L1.5BN

ADR tank code for Classes 1 and 3–9: liquid tank, 1.5 bar, openings B, valves/devices N.

L1.5BN is decoded part by part from the 4.3.4.1.1 table for Classes 1 and 3–9. Part 1 "L" is a tank for liquid-state substances (liquids, or solids handed over molten); part 2 "1.5" is minimum calculation pressure of 1.5 bar (see 6.8.2.1.14). Part 3 "B" (openings): filling or discharge openings at the bottom, each with 3 closures. Part 4 "N" (safety valves/devices): the tank has no 6.8.2.2.6 breather device and is not hermetically closed. The code gives the least stringent tank accepted; others may be used under the hierarchy in 4.3.4.1.2.

Note. Tank codes permitted in place of this one: see the rationalized approach and hierarchy in 4.3.4.1.2 (Volume II pages 217–222); not computed here.
