Foreword
This document EN 1803:2002 has been prepared by Technical Committee CEN/TC 23 "Transportable gas
cylinders", the secretariat of which is held by BSI.
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by endorsement, at the latest by August 2002, and conflicting national standards shall be withdrawn at the latest by
August 2002.
In this standard the annexes B, C, D and E are normative and the annexes A, F and G informative.
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 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 the technical annexes of the ADR.
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 a periodic inspection and testing procedure is that at the completion of the test the cylinders
may be reintroduced into service for a further period of time.
Experience of the inspection and testing of cylinders which is specified in this European Standard is an important
factor when determining whether a cylinder should be returned into service.
1 Scope
This European Standard specifies the requirements for periodic inspection and testing of welded, carbon steel
transportable gas cylinders intended for compressed and liquefied gases under pressure, of water capacity from
0,5 l up to 150 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
to be reintroduced into service for a further period of time. It also defines a procedure to qualify existing gas cylinders
for free movement between member states of the European Union (see annex A).
This standard does not apply to periodic inspection and testing of acetylene cylinders or composite (fully wrapped or
hoop-wrapped) steel cylinders.
This standard is primarily for industrial gases other than LPG but may also be applied for LPG. However for dedicated
LPG cylinders, see EN 1440, Transportable refillable welded steel cylinders for liquefied petroleum gas (LPG) –
Periodic requalification prepared by CEN/TC 286 – Liquefied petroleum gas equipment and accessories.
2 Normative references
This European Standard incorporates by dated or undated reference, provisions from other publications. These
normative references are cited at the appropriate place 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 the latest edition of the publication referred
to applies (including amendments).

3 Intervals between periodic inspection and test
In order to ensure continued safe operation, cylinders shall be periodically submitted to inspection and test in
accordance with annex B. A cylinder shall fall due for a periodic inspection and test on its first receipt by a filler after
the expiry of the interval in annex B.
NOTE  Table B.1 gives a list of the intervals between periodic inspections for some gases which complies with the current
RID/ADR regulations and also gives recommendations which could be subsequently adopted by the RID/ADR regulations.
Provided the cylinder has been subjected to normal conditions of use and has not been subjected to abusive and
abnormal conditions rendering the cylinder unsafe, 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. However it is
suggested that cylinders are retested within a period not exceeding twice the time interval.
In the case of cylinders used for emergency purposes (e.g. fire extinguishers, breathing apparatus), it is the
responsibility of the person in possession (owner or user) to submit it for a periodic inspection within the interval
specified in annex B or as specified in the relevant cylinder design standard/regulation, if this is shorter.
4 List of procedures for periodic inspection and test
The inspection and test shall be carried out only by competent persons who shall ensure that the cylinders are fit
for continued safe use.
NOTE  A competent person is a person who has the necessary technical knowledge, experience and authority to assess and
approve materials for use with gases and to define any special conditions of use that are necessary. Such a person will also
normally be formally qualified in an appropriate technical discipline.
Each cylinder shall be submitted to periodic inspection and test. The following procedures form the requirements
for such inspection and test, and are explained more fully in later clauses:
- identification of cylinder and preparation for inspection and test (clause 5);
- external visual inspection (clause 6);
- inspection of welds (6.2);
- internal visual inspection (clause 7);
- supplementary tests (clause 8);
- inspection of cylinder neck (clause 9);
- pressure test, proof test only (clause 10);
- repair of cylinders (clause 11);
- inspection of valve (clause 12);
- final operations (clause 13);
- rejection and rendering cylinders unserviceable (clause 14).
Where cylinders are manufactured according to National Regulations and are intended to be qualified under the
Transportable pressure equipment directive (TPED) for free movement and use between member states of the
European Union, additional requirements are specified in annex A.
It is recommended that the above listed tests are performed in the suggested sequence. In particular the internal
visual examination (clause 7) should be carried out before the pressure test (clause 10).
Cylinders which fail the inspection or tests shall be rejected (see clause 13). When, after the above tests, doubts
still exist as to the extent of a defect or the condition of a cylinder, then additional tests may be performed in
accordance with clause 8, until such doubts are positively resolved or the cylinder shall be rendered unserviceable.
Some cylinders rejected during periodic inspection and test may be recovered
