IntroductionThis European Standard is a three Part standard,belonging to a series of standards specifying gascylinder identification requirements.

Part 1 : Stampmarking

Part 2 : Precautionary labels

Part 3 : Colour coding

1 ScopeThis European Standard specifies stampmarking ofrefillable transportable gas cylinders of volume up toand greater than 150 L, including:

steel and aluminium gas cylinders;

gas cylinders of composite construction.

These being hereinafter referred to as `cylinders'.

Stampmarking of LPG cylinders is not covered by thisEuropean Standard.

2 Normative referencesThis European Standard incorporates, by dated orundated reference, provisions from other publications.These normative references are cited at theappropriate places in the text and the publications arelisted hereafter. For dated references, subsequentamendments to, or revisions of, any of thesepublications apply to this European Standard onlywhen incorporated in it by amendment or revision. Forundated references, the latest edition of the publicationreferred to applies.

3 DefinitionsFor the purposes of this European Standard, thefollowing definition applies:

3.1 stampmarkingPermanent markings, applied to the cylinders by hardmetal stamping, engraving, casting or other similarmethods. In the case of composite cylinders, somepermanent markings may be achieved by use of aprinted label, placed in the resin.

4 Application of stampmarkings4.1 GeneralAll mandatory stampmarkings are listed in thefollowing tables:

Table 1: Manufacturing stampmarkings(stampmarking No. 1 to No. 14)

Table 2: Operational stampmarkings (stampmarkingNo. 15 to No. 24).

Additional markings may be applied as requested bythe cylinder owner, provided the layout does not causeany confusion in their interpretation or in theinterpretation and clarity of the other mandatorymarkings.

4.2 WorkmanshipThe stampmarkings, shown in table 1 and table 2 shallbe stamped durably and legibly on a reinforced part ofthe cylinder. For welded steel cylinders somestampmarkings may appear on a welded identity plate,or any other part permanently attached to the cylinderand not subjected to gas pressure.

For composite cylinders some stampmarkings may beprinted on a label, to be placed in the resin (see 4.3).The characters in the stampmarkings should normallybe at least 5 mm in height. On small cylinders with anoutside diameter 140 mm, this height may be reduced,but in no case shall the characters be less than 2,5 mmin height.

The stamps used for marking shall have such radii asare necessary to prevent the formation of sharpnotches. This radius shall be a minimum of 0,2 mm.

4.3 Arrangements of stampmarkingsThe mandatory stampmarkings shown in table 1 andtable 2 shall be grouped on one side of the shoulder ofthe cylinder (front). Any additional stampmarkings maybe stamped on the other side (rear). Stampmarkingsrequired to be checked at the time of filling shall begrouped together. The lower part of the rear side shallbe kept free for periodic inspection markings (seeannex A).When an identity plate (or label for compositecylinders) is used, all the stampmarkings may be on asingle plate (or label) provided that the layout does notcause any confusion in their interpretation and followsgenerally the requirements of table 1 and table 2.For composite cylinders, when a label in the resin isused, the manufacturer's identification and themanufacturing serial number shall appear on theshoulder in conformity with annex A.

EN 1089-1 : 1996

BSI 1997

The arrangement of the stampmarkings shall be asshown in annex A.

When it is difficult to comply with annex A, a differentarrangement, of the stampmarking, may be usedsubject to the approval of the inspection authority. Thisdifferent arrangement shall not cause any confusion ininterpretation. In such a case stampmarkings may beon a permanently attached part (for example on theneck ring), with the exception of the manufacturer'sidentification and manufacturing serial number whichshall comply with annex A.
