AS 4484:2016 pdf download.Gas cylinders for industrial, scientific,medical and refrigerant use——Labelling and colour coding.
3 DEFINITIONS
For the purpose of this Standard, the definitions given in AS 2030.1 and those below apply.
3.1 Colour coding
The coloured materials applied or permanently affixed to a cylinder as a coating, sleeve or
some other form.
3.2 Composite cylinder
A fibre wrapped transportable gas cylinder that can be either hoop-wrapped or fully wrapped, and with or without an aluminium, steel or non-metallic liner, intended for compressed gas under pressure.
3.3 Industrial gas
Gas that is used in a technical process in industrial production or similar activity, excluding
medical and breathing applications (see ISO 10286, Entry Number 720).
3.4 Label
A means of providing identification of the contents of a gas cylinder including:
(a) Self-adhesive labels.
(b) Text which is applied by stencilling or other means.
(c) Any attachment to the cylinder whose sole purpose is to act as a label carrier.
3.5 Medical gas
Any gas or mixture of gases intended to be administered to patients for therapeutic, diagnostic or prophylactic purposes, or to be used for surgical tool applications (see AS 2473.3—2007).
NOTE: In Australia, medical gases are listed on the Australian Register of Therapeutic Goods.
3.6 Refrigerant gas
Gas that is used in a heat cycle usually including, for enhanced efficiency, a reversible phase change from a gas to a liquid (see Iso 10286, Entry Number 721).
3.7 Scientific gas
Gas that is used for analysis, calibration and other similar purposes in scientific laboratories (see ISO 10286, Entry Number 722).
4 LABELLING
4.1 General
The contents of a cylinder or bundle of cylinders, shall be identified on its label. The colours of the cylinder or bundle of cylinders shall be a secondary means of identification. Identification is achieved by symbols and text representing the contents of the cylinder being either directly printed or stencilled on the cylinder’s surface or in the form of pre-printed labels applied to the cylinder’s surface.
The cylinder shall be legibly labelled.
NOTE: ADG Code, Labelling of Workplace hazardous Chemicals CoP, SUSMP and TGO No. 69 have labelling requirements that may apply to gas cylinders.
As the colour coding of a cylinder includes the body colour and if applicable, its body labels, not more than 20% of the body of the cylinder may be used for promotional or marketing purposes.
4.2 Location and durability
4.2.1 Location of Iahel(s)
The required label(s) should be located as close as practicable to the valve end of each gas cylinder or to the outlet on a bundle of cylinders.
On a composite cylinder a complying label may be applied under a clear outer resin layer or under a clear outer filament winding.
4.2.2 Durability of/abe/s
Each label and their means of attachment shall be of material that ensures the label will remain in place and be legible after normal exposure to conditions incident to transport, storage and use.
4.3 Body labels
Body labels may be used on the body of a cylinder to identify the name and/or the chemical symbol of the contained gas.
When used, body labels shall be applied to two opposing sides of a cylinder, unless the water capacity of the cylinder is less than 15 L where a single body label may be applied. For bundles of cylinders a body label shall be applied to a minimum of one cylinder on at
least two opposite sides of the bundle. The body label text shall be in either black or white, with the colour being selected to
contrast with the body colour. Body labels shall be clearly visible.
4.4 Special labelling
Where the contents of the cylinder have a special condition, such as a specific storage temperature，or the constituents are in special or laboratory proportions， such as multi-component gas mixtures, the cylinder shall be identified in accordance with one of
the following: (a) By labelling to show the special condition, and the special or analysed proportions. (b) By a label indicating that the contents are a special gas mixture and referring to a report that is attached to the cylinder. The major constituent or balance gas need not have the percentage marked and should be shown as， ‘IN (name of balance gas)’ or BALANCE (name of balance gas)’. The minor constituents should have their proportions given as a percentage, or p.p.m. (volume) or other means as appropriate. AS 4484 pdf download.
