The property shall be classified n a descending order of hazard as follows
6.2.2.2 For gases with a single danger.
a) toxic and/or corrosive (in accordance with ISO 10298 and ISO 13338) — yellow;
b) flammable (in accordance with EN ISO 10156)— red:
C) oxidizing (in accordance with EN ISO 10156)— light blue;
d) inertt) — bright green
The colour BRIGHT GREEN shall not be used for air for medical use or breathing application (see 62.5).
6.2.2.3 For gases with more than one danger
When a gas or mixture has two hazard properties, then the cylinder shoulder shall be coloured in accordance with the primary hazard. The colour of the secondy hazard (flammable or oxidizing) may also be applied to the cylinder shoulder:
a) toxic (and/or corrosive) and flammable — yellow plus red,
b) toxic (andlor corrosive) and oxidizing — yellow plus light blue.
6.2.3 Specific single gases
6.2.3.1 The following gases shall be identified by specific colours rather than the colour system defined in
6.2.2.
a) Flammable gases:
Acetylene — Maroon.
b) Oxidizing gases:
Oxygen — White, Nitrous oxide — Blue.
6.2.3.2 Inert gases for medical application shall be further differentiated by use of the following colours:
a) Argon — Dark green;
b) Nitrogen — Black;
C) Carbon dioxide — Grey:
d) Helium — Brown.
Specific colours of single gases described above are identical to ISO 32.
These colours may also be used for applications other than medical instead of the bright green colour (inert) as indicated in 6,2.2.
NOTE Inert gases br medical use se also differentiated from industrial use by the colouration of the gas c1I’ider
body, white for medical use (see 6.3).
6.2.4 Mixtures of inert gases
Instead of the hazard colour as indicated in 6.22. combinations of colours (maximum two, see Annex D) of
the specific component gases listed in 6.23.2 may be used to identify the cylinder contents.
6.2.5 Oxygen mixtures and air for medical use and breathing application
For medical use, the following gas mixtures containing at least 20 % oxygen shall be Identified using the colour of the components listed In 62.3. These colours may also be used (or breathing applications other than medical.
a) Air or synthetic air — white plus black:
b) Oxygenmeliun’i — white plus brown;
c) Oxygen!carbon dioxide — white plus 9rey;
d) Oxygen!nitrous oxide — white plus biue.
lithe gas mixture contains more than one other gas than oxygen, then 6.2.2 shall be applied. All the above gas mixtures containing less than 20 % oxygen shall be coloured bright green.
NOTE A deviation from this reqemenl is possible for specific mixture use for deep diving, e.g. helium with minor percentage of oxen.
These colours shall neither be used for mdustrial gas mixtures containing these components, nor also for breathing gases with less than 20 % oxygen winch are life threatening to breathe
6.2.6 Specific medical gas mixtures
In case of medical gas mixture for inhalation containing less I 000 ppm(\IN) of NO (nitric oxide) in nitrogen a specific colour on the shoulder, Turkish blue, shall be used.
6.3 Body
All cylinders for gas for medical use shall be coloured white along the body of the cylinder. While colouration of the body shall not be used for any other applications.
7 Implementation
Cylinders colour coded in accordance with this European Standard shall have the letter N” marked twice on the shoulder of the cylinder except if there is no risk of mis-interpretation. When “N is used, these markings shall be positioned diametrically opposed and displayed in a colour distinct from the colotvs of the cylinder shoulder. The size and shape of “N” shall be as indicated in Annex C.
