Foreword
This document (EN ISO 11623:2002) has been prepared by Technical Committee CEN/TC 23 "Transportable
gas cylinders", the secretariat of which is held by BSI, in collaboration with Technical Committee ISO/TC 58
"Gas cylinders".
This European Standard shall be given the status of a national standard, either by publication of an identical
text or by endorsement, at the latest by September 2002, and conflicting national standards shall be
withdrawn at the latest by September 2002.
This document has been prepared under a mandate given to CEN by the European Commission and the
European Free Trade Association, and supports the objectives of the framework Directives on Transport of
Dangerous Goods.
This European Standard has been submitted for reference into the RID and/or or in the technical annexes of
the ADR. Therefore in this context the standards listed in the normative references and covering basic
requirements of the RID/ADR not addressed within the present standard are normative only when the
standards themselves are referred to in the RID and/or in the technical annexes of the ADR.
Annexes A, C and D are informative.
Annex B and ZA are normative.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to implement this European Standard : Austria, Belgium, Czech Republic, Denmark,
Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway,
Portugal, Spain, Sweden, Switzerland and the United Kingdom.
Introduction
The principal aim of periodic inspection and testing is that at the completion of the test the cylinders may be
reintroduced into service for a further period of time. It is not possible to identify all considerations for inspecting
and re-testing of composite cylinders in this publication. Questions regarding specific cylinders should be
directed to the manufacturer.
1 Scope
This standard specifies the requirements for periodic inspection and testing of hoop wrapped and fully wrapped
composite transportable gas cylinders, with aluminium, steel or non-metallic liners or of linerless construction,
intended for compressed, liquefied or dissolved gases under pressure, of water capacity from 0,5 l up to 450 l.
NOTE As far as practicable, this standard may also be applied to cylinders of less than 0,5 l water capacity.
This standard specifies the requirements for periodic inspection and testing to verify the integrity of such gas
cylinders for further service.
2 Normative references

These normative references are cited at the appropriate places in the text and the publications are listed
hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply
to this European Standard only when incorporated in it by amendment or revision. For undated references

3 Terms and definitions
For the purposes of this European standard, the following terms and definitions apply.
3.1
burst pressure
maximum pressure attained during a burst test
3.2
composite overwrap
fibres and matrix taken together as a combined unit
3.3
exterior coating
layer of material applied to the cylinder as a protective coating or for cosmetic purposes
NOTE Not all composite cylinders will have a special exterior coating.
3.4
fibre
load-carrying part of the composite overwrap e.g. glass, aramid and carbon
3.5
fully wrapped composite cylinder without liner
cylinder manufactured only from continuous fibre strands in a resin matrix wrapped in both circumferential
and longitudinal directions
3.6
fully wrapped composite cylinder with liner
steel, aluminium alloy or non-metallic liner wrapped with continuous fibre strands in a resin matrix both
circumferentially and longitudinally
3.7
hoop wrapped composite cylinder
seamless steel or aluminium alloy liner wrapped with continuous fibre strands or steel wire around only the
cylindrical body of the liner, leaving the metal in the neck and base regions exposed. The fibre strands are
embedded in a resin matrix
3.8
identification label
label containing the permanent markings required by the relevant design document and EN 1089-1 or
ISO 13769
3.9
LC
50 % lethal concentration, as defined in ISO 10298
3.10
lifetime
service life of the cylinder, if specified on the design drawing
3.11
liner
inner portion of the composite cylinder designed both to contain the gas and transmit the gas pressure to the
composite overwrap. For hoop wrapped cylinders this provides a substantial structural strength.
3.12
non-metallic liner
liner made from thermoplastic, thermosetting, or elastomer material
3.13
protective sleeve

3.16
rejected cylinder
cylinder not fit for service in its present condition
3.17
toxic gases
when LC > 200 p.p.m. V/V but 5 000 p.p.m. V/V, in accordance with ISO 10298
3.18
very toxic gases
when LC 200 p.p.m. V/V, in accordance with ISO 10298
4 Intervals between periodic inspection and testing
A cylinder shall fall due for periodic inspection and test on its first receipt by a filler after the expiry of the interval
in Tables 1 to 4. However, a shorter period than that inTables 1 to 4 may be stipulated by the inspection body
for the first re-test only.
There is no general requirement for the user to return a gas cylinder before the contents have been used even
though the test interval may have lapsed. When the lifetime has expired, the cylinder shall not be refilled and
shall be removed from service when presented for the next filling (see clause 13).
In the case of cylinders used for emergency purposes it is the responsibility of the owner or user to submit it for
a periodic inspection within the specified interval.
The lists of gases in Tables 1 to 4 are intended as guides only. Reference shall be made to the manufacturer or
inspection body if there is a question on the re-test period for specific gases.
