BS EN 1089-3:2011EN 1089-3:2011 (E) 4 Introduction The labelling of gas cylinde
20、rs as required by the RID/ADR- Regulations is the primary method of indicating dangers of cylinder contents. However, colour coding is used to identify the contents of gas cylinders from a distance, e.g. in case of a fire. It is recognized that other systems are in use and may be used in conjunction
21、 with the requirements of this European Standard. This European standard, along with EN ISO 13769, EN ISO 21007-1 and EN ISO 21007-2 belongs to a series of European Standards specifying gas cylinder identification requirements. NOTE Labelling and marking of gas cylinders is subject to provisions of
22、RID/ADR which take precedence over marking clauses in this standard. BS EN 1089-3:2011EN 1089-3:2011 (E) 5 1 Scope This European Standard specifies a colour coding system for the secondary method of identification of the contents of gas cylinders for industrial gases, breathing gas application and g
23、ases for medical use with particular reference to the properties of the gas or gas mixture. This European Standard does not apply to cylinders containing liquefied petroleum gas (LPG), to refrigerant gases, to portable fire extinguishers or stationary cylinder extinguishing. Bundle colour coding is
24、not addressed by this or other standards. NOTE LPG includes substances carried under the UN number 1965 “Hydrocarbon gas mixture, liquefied, N.O.S.“ 2 Normative references The following referenced documents are indispensable for the application of this document.

30、poses of this document, the following symbols apply. 4.1 N.O.S. not otherwise specified 5 Principle Colour coding is used to give information about the contents of gas cylinders from a distance e.g. in case of emergency and to distinguish between cylinders used for industrial and medical uses. For a
31、ll applications, hazard/identification colours shall be applied to cylinder shoulders. For gases for medical use, the body of the cylinder shall also be colour coded (see 6.3). For applications other than medical, the cylinder body may be coloured. The use of a colour for the cylinder body that allo
32、ws misinterpretation of the hazard of the gas is not allowed. Colours used shall be in accordance with RAL register 840HR given in Annex A or equivalent. 6 Colour coding system 6.1 General The following colour coding requirements are applicable to the shoulder and the body of the cylinder. 6.2 Shoul
33、der 6.2.1 General Gas cylinders are assigned colours using three methods. Colours are chosen based on the properties of the contents in accordance with the hazard of the gas filled in the cylinder (6.2.2). Some specific gases and gas mixtures are assigned colours relevant to that gas or gas mixture
34、as noted in 6.2.3 and 6.2.6. Instead of the hazard colour, other colour(s) may be assigned based on the components of a gas mixture (6.2.3 or 6.2.4 or 6.2.5). Annex D gives guidance for the selection of shoulder colours. 6.2.2 Gas properties 6.2.2.1 Unless specifically identified in 6.2.3, 6.2.4, 6.
35、2.5 or 6.2.6, all gases and gas mixtures shall be identified by a colour coding indicating the properties of the contents in accordance with the colour of the danger labels as specified in RID/ADR. When two colours are applied to the cylinder shoulder, they should be in one of the formats (bands or
36、quadrants) identified in Annex B. BS EN 1089-3:2011EN 1089-3:2011 (E) 7 The property shall be classified in 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
37、 EN ISO 10156) red; c) oxidizing (in accordance with EN ISO 10156) light blue; d) inert1) bright green. The colour BRIGHT GREEN shall not be used for air for medical use or breathing application (see 6.2.5). 6.2.2.3 For gases with more than one danger: When a gas or mixture has two hazard properties
38、, then the cylinder shoulder shall be coloured in accordance with the primary hazard. The colour of the secondary hazard (flammable or oxidizing) may also be applied to the cylinder shoulder: a) toxic (and/or corrosive) and flammable yellow plus red; b) toxic (and/or corrosive) and oxidizing yellow
39、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 sha
40、ll 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 b
41、right green colour (inert) as indicated in 6.2.2. 1) in accordance with 3.2 BS EN 1089-3:2011EN 1089-3:2011 (E) 8 NOTE Inert gases for medical use are also differentiated from industrial use by the colouration of the gas cylinder body, white for medical use (see 6.3). 6.2.4 Mixtures of inert gases I
42、nstead of the hazard colour as indicated in 6.2.2, combinations of colours (maximum two, see Annex D) of the specific component gases listed in 6.2.3.2 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 followin
43、g gas mixtures containing at least 20 % oxygen shall be identified using the colour of the components listed in 6.2.3. These colours may also be used for breathing applications other than medical. a) Air or synthetic air white plus black; b) Oxygen/helium white plus brown; c) Oxygen/carbon dioxide w
44、hite plus grey; d) Oxygen/nitrous oxide white plus blue. If the 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 requirement is possible for sp
45、ecific mixture use for deep diving, e.g. helium with minor percentage of oxygen. These colours shall neither be used for industrial gas mixtures containing these components, nor also for breathing gases with less than 20 % oxygen which are life threatening to breathe. 6.2.6 Specific medical gas mixt
46、ures In case of medical gas mixture for inhalation containing less 1 000 ppm(V/V) 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. White colouration
47、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
48、be positioned diametrically opposed and displayed in a colour distinct from the colours of the cylinder shoulder. The size and shape of “N” shall be as indicated in Annex C.
