NACIONALNI UVOD
Standard SIST EN 12542 ((sl)en), Oprema in pribor za utekočinjeni naftni plin (UNP) – Stabilne,
varjene, jeklene valjaste posode serijske proizvodnje za skladiščenje utekočinjenega naftnega plina
(UNP), katerih prostornina ni večja od 13 m³ – Konstruiranje in proizvodnja, 2010, ima status
slovenskega standarda in je po metodi ponatisa izvirnika z nacionalnim dodatkom privzet evropski
standard EN 12542 (en), LPG equipment and accessories – Static welded steel cylindrical tanks,
serially produced for the storage of Liquefied Petroleum Gas (LPG) having a volume not greater than
13 m³ – Design and manufacture, 2010.
Ta slovenski standard nadomešča slovenski standard SIST EN 12542:2002 in dopolnilo SIST EN
12542:2002/A1:2005 ter slovenski standard SIST EN 14075:2003 in dopolnilo SIST EN
14075:2003/A1:2005.
NACIONALNI PREDGOVOR
Evropski standard EN 12542:2010 je pripravil tehnični odbor Evropskega komiteja za standardizacijo
CEN/TC 286 Oprema in pribor za utekočinjeni naftni plin.
Pripravo tega standarda sta CEN poverila Evropska komisija in Evropsko združenje za prosto
trgovino. Ta evropski standard ustreza bistvenim zahtevam evropske Direktive 97/23/ES.
Odločitev za izdajo tega standarda je dne 14. oktobra 2010 sprejel tehnični odbor SIST/TC TLP
Tlačne posode.
NACIONALNI DODATEK
Celotno ozemlje Slovenije spada v III. klimatsko cono. Najnižja temperatura, ki jo je treba upoštevati
pri konstruiranju, je –20 °C.

Foreword
This document (EN 12542:2010) 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text or by endorsement, at the latest by February 2011, and conflicting national standards shall be withdrawn
at the latest by February 2011.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights.
This document supersedes EN 12542:2002, EN 14075:2002.
This document has been prepared under a mandate given to CEN by the European Commission and the
European Free Trade Association, and supports essential requirements of EU Directive(s).
For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this document.
The main technical changes in this revision include:
 widening of the Scope to include requirements for underground tanks;
 addition of environmental considerations;
 reference to the latest welding standards; and
 introduction of radioscopy as a permitted alternative to radiographic examination of welds.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech
Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia,
Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain,
Sweden, Switzerland and the United Kingdom.
Introduction
This European Standard calls for the use of substances and procedures that may be injurious to health and/or
the environment if adequate precautions are not taken. It refers only to technical suitability and does not
absolve the user from legal obligations at any stage.
Protection of the environment is a key political issue in Europe and elsewhere. Protection of the environment
is taken in a very broad sense. What is meant is the total life cycle aspects of e.g. a product on the
environment, including expenditure of energy and during all phases from mining of raw materials, fabrication,
packaging, distribution, use, scrapping, recycling of materials, etc.
NOTE 1 Annex J indicates which clauses in this standard address environmental issues.
Provisions should be restricted to a general guidance. Limit values are specified in national laws.
It is recommended that manufacturers develop an environmental management policy. For guidance see
ISO 14000 series
It has been assumed in the drafting of this European Standard that the execution of its provisions is entrusted
to appropriately qualified and experienced people.
All pressures are gauge pressures unless otherwise stated.
NOTE 2 This European Standard requires measurement of material properties, dimensions and pressures. All such
measurements are subject to a degree of uncertainty due to tolerances in measuring equipment, etc. It may be beneficial
to refer to the leaflet "Measurement Uncertainty Leaflet (SP INFO 2000 27 uncertainty.pdf)".
1 Scope
This European Standard specifies requirements for the design and manufacture of static welded steel
cylindrical tanks, serially produced for the storage of liquefied petroleum gas (LPG) with a volume not greater
than 13 m and for installation above or below ground.
