European foreword
This document (EN 12817:2019) has been prepared by Technical Committee CEN/TC 286 “Liquefied
petroleum gas equipment and accessories”, the secretariat of which is held by NSAI.
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 2019, and conflicting national standards shall
be withdrawn at the latest by September 2019.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document supersedes EN 12817:2010.
EN 12817:2010 was thereby technically revised.
In using this document, prepared in the field of application of Article 153 of the treaty on the functioning
of the European Union, users are aware that standards have no formal legal relationship with Directives
that may have been made under Article 153 of the treaty on the functioning of the European Union. In
addition, national legislation in the Member states may contain more stringent requirements than the
minimum requirements of a Directive based on Article 153. Information on the relationship between the
national legislation implementing Directives based on Article 153 and this EN may be given in a national
foreword of the national standard implementing this EN.
According to the CEN-CENELEC Internal Regulations, the national standards organisations of the
following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia,
Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France,
Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands,
Norway, Poland, Portugal, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and

Introduction
3
Inspection and requalification regimes for pressure vessels up to and including 13 m have developed in
various countries in different ways that range from defined to variable inspection periods with
requalification regimes achieved by various methods. This document for inspection and requalification
is based on European countries’ legislation and codes of practice and industry codes of practice. In
addition, use of LPG in different applications has encouraged the industry to approach the requirements
for inspection and requalification in different ways for each application.
This document calls for the use of substances and procedures that can be injurious to health if adequate
precautions are not taken. It refers to technical suitability and does not absolve the user from legal
obligations relating to health and safety at any stage.
Protection of the environment is a key political issue in Europe and elsewhere; for CEN/TC 286 this is
covered in CEN/TS 16765 [1], and this Technical Specification should be read in conjunction with this
standard.
It has been assumed in the drafting of this document that execution of its provisions is entrusted to
appropriately qualified and experienced people.

NOTE Methods for detecting leaks include:
— visual inspection;
— smell;
— listening;
— use of gas detectors;
— leak detection fluid.
5 Written scheme
5.1 Each pressure vessel and its fittings shall be included in a written scheme, prepared by a competent
person, containing inspection and testing information, taking into account the requirements of Clauses 6
to 8.
5.2 If duties are shared between different parties, the written scheme shall clearly identify the
respective areas of responsibility.
5.3 Intervals between inspections shall be parts of the written scheme and shall be determined by
consideration of the following:
— the design specification of the pressure vessel and its equipment;
— the corrosion protection system on the pressure vessel;
— the system used to ensure that the LPG quality conforms to its specifications/standards, and that it
does not contain components damaging to the material of the pressure vessel or its fittings;
— the maintenance program of the pressure vessel.
NOTE The requirements for the written scheme can also be determined by national regulations.
