ADR tank code RxBN

ADR tank code for Class 2 gases: refrigerated liquefied gas tank, X (test pressure from 4.3.3.2.5), openings B, valves/devices N.

RxBN is decoded part by part from the 4.3.3.1.1 table for Class 2 gases. Part 1 "R" is a tank for refrigerated liquefied gases; part 2 "X" is the minimum relevant test pressure taken from the table in 4.3.3.2.5 for the gas. Part 3 "B" (openings): tank filled or discharged from the bottom through openings having 3 closures; or a battery-vehicle/MEGC with openings below the liquid surface or for compressed gases. Part 4 "N" (safety valves/devices): the tank has a safety valve conforming to 6.8.3.2.9 / 6.8.3.2.10 that is not hermetically closed. The code gives the least stringent tank accepted; others may be used under the hierarchy in 4.3.3.1.2.

Note. Tank codes permitted in place of this one: see the hierarchy in 4.3.3.1.2 (Volume II page 208); not computed here. "x" in the code stands for the value X, read per gas from the 4.3.3.2.5 table.
