Foreword
This document (EN 13445-5:2002/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 13445-5:2002 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national standards shall be withdrawn at the latest by December 2007.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 13445-5 up to issue 26 (April 2007).
The document includes the text of the amendment itself. The corrected pages of EN 13445-5 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.
1 Scope
Add a new third paragraph between the current second and third paragraphs:
Special provisions for vessels or vessel parts working in the creep range are given in Clause 5, Clause 6,
Clause 10, Annex F and Annex I of this Part.
_______________________________________________________________________________________
5 Technical documentation
5.2.1 General description of the pressure vessel
Add:
8) If the vessel is working in the creep range, the following additional information:
 the design life (e.g. 100000 h) and expected life for each load case
 the parts of the vessel which are subjected to creep
 the value of the weld creep strength reduction factor which has been used for each weld
joint subjected to creep
 whether lifetime monitoring, as defined in Clause 19 of EN 13445-3:2002, is or not being
applied
_______________________________________________________________________________________
6 Inspection and testing during fabrication
6.6 Non-destructive testing of welded joints
6.6.1 Extent of non-destructive testing
Add in the second paragraph:
For serially produced pressure vessels an alternative route is given in Annex A. This annex is not applicable
for vessels or vessel parts working in the creep range.
_______________________________________________________________________________________
6.6.1.1 Use of testing groups
6.6.1.1.1 General
Replace by the following text:
The non-destructive testing of welded joints for final acceptance purposes shall depend upon the testing group
or subgroup of the welded joint under consideration.
In Table 6.6.1-1, testing groups 1, 2, 3 and 4 apply below the creep range. Testing groups 1, 2 and 3 are
subdivided into sub-groups 1a, 1b, 2a, 2b, 3a, 3b, in order to reflect crack sensitivity of the material. In Table
F.2-1 of Annex F, testing sub-groups 1c and 3c apply to creep.
NOTE 1 The testing groups or sub-groups take into consideration the manufacturing difficulties associated with
different groups of steel, maximum thickness, welding process, service temperature range and joint coefficient. It is
intended that any of the testing groups will provide adequate integrity for typical applications within the limitations
contained within Tables 6.6.1-1 and F.2-1.
For vessels (or vessel parts) designed according to Design by Analysis – Direct Route of Annex B of EN
13445-3:2002 or designed according to 6.3 of EN 13445-3:2002, only testing group 1 is permissible.
NOTE 2 Further restrictions are given in Annex A of EN 13445-3:2002.
For vessels designed by experimental methods, the testing group to be considered for the vessel or vessel
part shall be determined according to the rules given in Table 6.6.1-1 and the possible limitations stated in
20.5 of EN 13445-3:2002.
NOTE 3 The weld joint coefficient is not used in design by the experimental method without calculation.
For vessels (or vessel parts) working in the creep range only testing groups 1c and 3c are permissible. The
extent of NDT is given in Table F.2-1 of Annex F. Testing groups 1, 2 and 3 are permissible for any welded
joint not subjected to creep.

10 Final assessment
10.2.3.3 Standard hydrostatic test
Add at the end of a) of 10.2.3.3.1
Formula 10.2.3.3.1-1 applies when the maximum allowable temperature t occurs at the maximum
smax
allowable pressure P .
s
When there exists more than one set of coincident design pressure and temperature, the test pressure shall
be determined as above for each combination substituting the actual coincident pressure and temperature
values in lieu of P and t in formula 10.2.3.3.1-1. The test pressure of the vessel shall be the largest
s smax
value of test pressures determined.
_______________________________________________________________________________________
Add at the end of 10.2.3.3.1 a e) subclause:
e) For vessels working in the creep range the test pressure shall be calculated as above but using f and
t
s
f determined from creep strength according to 19.2 of EN 13445-3:2002 or using the following substitutions:
tc
In a)
 f is replaced by f
