This page tries to reflect the official colors.

It would be nice, if you could send more specifications to me .
Questionmarks mean that i have no data to fill that field.

1. EN1089-3 replaces the old national Colorcodes in Europe. It is not in charge for liquit gas and fire extinguishers.
   The two capital letters "N" mark that it´s the new code.
   If the "N" is white, back or blue depends on maximum contrast to the head-colors.
   The color for the body is not mandantory. White bodies are recommended for gases with breathable quality, but this does not mean that yellow bodies are forbidden for SCUBA-tanks.
   Shining-green is not the codecolor for breathing air, it is used for low quality air and several other gases like shelter-gas (Ar-CO2-mix).
   The colors only inform about problematic characteristics, the gas-sticker is the only bindig information what gas is exactly in the tank.

B!W stands for

"Ring - " is my shortcut for: a ring does not exist, shoulder color down to the body.

"Belt - " means a belt does not exist, use same the color as for the body.

"Body - " means the body has the same color as the shoulder

How a SCUBA-tank according to EN 1089-3 could look like:

White shoulder with

black ring, "N" for new colourcode,

body in white or like here in any other colour.
