Foreword
This document (EN 13445-1:2002/A3:2007) has been prepared by Technical Committee CEN/TC 54 “Unfired
pressure vessels”, the secretariat of which is held by BSI.
This Amendment to the European Standard EN 13445-1:2002 shall be given the status of a national standard,
either by publication of an identical text or by endorsement, at the latest by February 2008, and conflicting
national standards shall be withdrawn at the latest by February 2008.
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 97/23/EC.
For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this document.
The amendment is based on EN 13445-1:2002 up to issue 27 (June 2007).
The document includes the text of the amendment itself. The corrected pages of EN 13445-1 will be delivered
as issue 28 of the standard.
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, 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 United Kingdom.
Introduction
Delete all text except the first paragraph and the note following it:
Add the following after the note:
In Parts 2 to 5 only pressure vessels manufactured from steels and steel castings as detailed in Part 2 of this
standard are covered. Parts 6 and 8 specifically deal with vessels of spheroidal graphite cast iron and
aluminium, respectively, where special considerations apply.
Part 1
This part contains general information on the scope of the standard as well as terms, definitions, quantities,
symbols and units which are applied throughout the standard.
Part 2
This part deals with the general philosophy on materials, material grouping and low temperature behaviour. It
is limited to steel with sufficient ductility and, for components operating in the creep range, sufficient creep
ductility.
Part 2 also provides the general requirements for establishing technical delivery conditions and the
requirements for marking of material.
Part 3
This part of the standard gives the rules to be used for design and calculation under internal and/or external
pressure (as applicable), local loads and actions other than pressure. The rules provided are both design by
formulae (DBF), design by analysis (DBA) and design by experiment (DBE).
The part also sets the requirements for when fatigue analysis must be performed and the rules to be followed
when this is the case.
Part 4
This part is based on existing good practice in previous national European Standards on manufacturing. It
covers forming, welding procedures and welding qualification, production testing, and post weld heat
treatment and repairs. Rules are also provided for material traceability and tolerances.
Part 5
This part covers all those inspection and testing activities associated with the verification of the pressure
vessel for compliance with the standard, including design review by the manufacturer and supporting technical
documentation, NDT and other inspection activities including document control, material traceability, joint
preparation and welding.
The level of testing is driven by the selection of the vessel testing group. Basically, the testing group
determines the level of NDT and the joint coefficient used in the design.
In terms of NDT, the overall philosophy has been the general adoption of EN ISO 5817:2003 quality level 'C'
for predominantly non-cyclic loaded vessels and level 'B' for vessels subject to cyclic loadings.
Part 6
This part contains special rules for material, design, fabrication, inspection, and testing of pressure vessels
made from spheroidal graphite cast iron. In general the rules in the relevant parts of parts 2–5 apply with
additions and exceptions outlined in this part.
Part 7
This part gives guidance on how to use the conformity assessment procedures in the Pressure Equipment
Directive 97/23/EC. It is not a standard, but merely a CEN Technical Report.
Part 8
This part contains special rules for material, desig
