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
t nc,t
s s
In b)
f is replaced by f
tc nc,tc
where:
f is the nominal design stress for normal operating load cases of the part at maximum
nc,t
s
allowable temperature, using time independent material characteristics,
f is the nominal design stress for normal operating load cases of the part under consideration
nc,tc
at calculation temperature, using time independent material characteristics. These stresses being taken from
Annex S of EN 13445-3:2002 if no yield strength data are available from the materials standard at that
temperature.
For vessels or parts designed to testing sub-group 1c this stress may be determined at the highest
temperature for which time independent tensile properties are available in the materials standard.
From the three methods described above for determining test pressure, a consistent method shall be used for
all parts.
NOTE The level of the test pressure has no relevance to the safety of the vessel with respect to creep behaviour.
The test pressure derived using Annex S of EN 13445-3:2002 is a logical extrapolation of the practice below the creep
range. The value derived using the yield strength at the highest temperature for which time independent tensile properties
are available in the materials standard gives a lower test pressure, but an adequate demonstration of strength. The value
derived from creep strength gives a higher pressure which may be difficult to achieve with large vessels.
Annex F
(normative)
Inspection and testing of pressure vessels or parts subject to creep
Insert this new Annex F.
F.1 General
For vessels or vessel parts subject to creep, Quality Level B of EN ISO 5817:2003 is the reference quality
level for maximum allowable imperfection in these areas. The absence of surface imperfections (no undercut,
no root concavity and no lack of penetration) and the necessity of smooth transitions are essential. Similarly,
shape imperfections, such as peaking, may be critical and the manufacturing tolerances specified in EN
13445-4:2002 shall be respected. In particular, the maximum peaking of EN 13445-4:2002 or the value
permitted by the design methods of EN 13445-3:2002 shall not be exceeded.
Extent of Non-Destructive Testing (NDT) of this annex is based on the general requirements of testing sub-
groups 1c and 3c, as defined in Table F.2-1.
If lifetime monitoring is a design option, any procedure for control and testing shall be part of the Instructions
for use prepared by the manufacturer.
NOTE Supplementary tests may also be prescribed by the manufacturer. These tests will be specified in the
Instructions for use.
F.2 Extent of inspection and testing
In addition to the requirements of 6.6.2, all areas subject to creep shall be inspected by NDT, according to the
following Table F.2-1.
