Unfired pressure vessels - Part 3: Design

Resolution 467/2004 was to split WI 00054031 into two work items.  Work item 00054052 was however created instead and 00054031 was left intact.
Amendement 1 to Part 3, was initially registerd under WI 037 which is split.

Foreword
This document (EN 13445-3:2002/A1:2007 - 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 13445-3:2002 shall be given the status of a national
standard, either by publication of an identical text or by endorsement, at the latest by December 2007,
and conflicting national standards shall be withdrawn at the latest by December 2007.
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 97/23/EC, see informative Annex ZA, which is an integral part of this
document.
This amendment is based on EN 13445-3 up to issue 26 (April 2007).
The document includes the text of the amendment itself. The corrected pages of EN 13445-3 will be
delivered as issue 27 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.
2 Normative references
Amend the third reference to read:
EN 764-1:2004, Pressure equipment – Part 1: Terminology – Pressure, temperature, volume,
nominal size.
_________________________________________________________________________________
3 Terms and definitions
Add a new definition 3.23:
3.23
creep range
temperature range in which material characteristics used in design are time dependent
Add a NOTE:
NOTE See also 5.1.
_________________________________________________________________________________________
5 Basic design criteria
5.1 General
Replace the existing text with:
Part 3 is applicable only when:
a) materials and welds are not subject to localized corrosion in the presence of products which the
vessel is to contain or which can be present in the vessel under reasonably foreseeable
conditions.
b) either all calculation temperatures are below the creep range or a calculation temperature is in
the creep range and time dependent material characteristics are available in the materials
standard.
NOTE See definition 3.23 of creep range.
For the purpose of design, the creep range is the temperature range in which time independent
material characteristics are no more governing in the determination of the nominal design stress.
The material strength characteristics used shall be related to the specified lifetimes in the various
creep load cases
_________________________________________________________________________________
5.3.3 Failure modes considered in this Part
Add:
f) creep rupture;
g) creep deformation;
h) creep fatigue.
