Foreword
This document (EN 12542:2002:A1:2004) has been prepared by Technical Committee CEN/TC 286 “Liquefied
Petroleum Gas equipment and accessories”, the secretariat of which is held by NSAI.
This Amendment to the European Standard EN 12542:2002 shall be given the status of a national standard,
either by publication of an identical text or by endorsement, at the latest by May 2005, and conflicting national
standards shall be withdrawn at the latest by May 2005.
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.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic,
Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania,
Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden, Switzerland
and United Kingdom.

laws of the Member States concerning pressure equipment
3.2
yield strength
upper yield strength R or, for steels that do not exhibit a definite yield, the 0,2 % proof stress
eH
NOTE These properties are equivalent to those specified by the symbol R , in the PED.

3.3
serially produced tanks
more than one tank manufactured in the same factory to a common design using the same material and
manufacturing procedure and produced with no major interruption within a given period of time
3.4
production-batch
group of pressure parts or finished tanks, made consecutively by the same manufacturer using the same
manufacturing techniques to the same design, nominal size and material specifications on the same
production machinery and subject to the same heat treatment conditions
NOTE In this context, consecutively need not imply continuous production.
3.5
cold forming
forming at temperatures not less than 25 °C below the maximum permissible temperature for stress relieving
in accordance with the material specification
3.6
hot forming
forming at temperatures above the maximum permissible temperature for stress relieving in accordance with
the material specification
3.7
climatic area
geographic area agreed or defined by the relevant national authorities, or other bodies, responsible for
defining the design conditions for LPG storage tanks, in the country(ies) where the tank is intended to be
operated. The area is used to define the reference temperature for design pressure and filling
3.8
design pressure
gauge pressure used in design formulae
NOTE For tanks made to this standard, the design pressure is equal to the “Maximum allowable pressure”, PS, in the
PED.
3.9
manufacturer
manufacturer of the tank unless otherwise specified
