Annex B
(normative)
Requirements for prevention of brittle fracture at low temperatures
B.1 General
This annex distinguishes between pressure equipment that has normal operation temperatures higher or
lower than 50 °C.
For pressure equipment with normal operation temperatures higher than 50 °C B.5 applies. If B.5 is not
applicable, the following rules for lower normal operation temperatures shall be used.
For pressure equipment with design temperature equal to or less than 50 °C this annex specifies three
1)
alternative methods for establishing criteria for the avoidance of low temperature brittle fracture of steels in
the form of plate, strip, tubes, fittings, forgings, castings, flanges, fasteners and weldments used in pressure
parts. The criteria are based on impact energy requirements at specified temperatures for the base material,
heat affected zone (including the fusion line) and weld metals.
The three methods are:
Method 1 Technical requirements developed from the principles of fracture mechanics and from operating
experience and applicable to all steels, but limited to certain thicknesses depending on
minimum impact energy requirements as specified in harmonized European material standards
for pressure equipment (see Table B.2–1).
Method 2 Technical requirements developed from the same principle of fracture mechanics as method 1
and from operating experiences but only applicable to C, CMn and low alloy ferritic steels and
austenitic ferritic steels with a specified minimum yield strength ≤ 500 N/mm . This method may
be applied to a wider range of thicknesses and temperatures than method 1 (see Figures B.2–1
to B.2–12).
Method 3 The application of a fracture mechanics analysis. This general method is applicable to cases
not covered by methods 1 or 2. This method may also be used to justify deviations from the
requirements of method 1 or 2. Only general guidance is given on the use of this method which
shall only be used in agreement with the parties concerned.
Each of the three methods may be used independently. It is only necessary to satisfy the requirement of any
one method.
All applicable combinations of the temperatures T (minimum metal temperature) and T (temperature
M S
adjustment term) shall be considered and the lowest possible T -value (design reference temperature) shall
R
be used for the determination of the required material impact test temperature.
NOTE For definitions of temperature terms see 3.1.1 to 3.1.4.

Including temperatures at pressure tests
EN 13445-2:2002/prA5:2006 (E)
B.2 Material selection and impact energy requirements
The methods specified in B.2.1 (method 1) or B.2.2 (method 2) shall be used to determine impact energy
required to avoid brittle fracture. Alternatively, B.2.3 (method 3) may be used to determine the required
toughness. The method used shall be fully documented, in order to ensure that compliance can be verified.
Reference thickness for constructional details is defined in table B.6-1.
B.2.1 Method 1
B.2.1.1 General
Method 1 allows the selection of materials taken from harmonised European standards with regard to
avoidance of brittle fracture. Table B.2–1 gives an overview to the following tables by steel type and product
form.
The weld metal, the heat affected zone and other parts affected by manufacturing processes shall satisfy the
same impact test requirements as the guaranteed minimum properties for the base material at T given in the
R
tables.
The tables list design reference temperatures for maximum thickness at given strength levels represented by
steels from European standards with guaranteed minimum strength and impact properties. Where it is not
possible to achieve these minimum properties after fabrication, tougher material shall be selected.

NOTE Requirements for austenitic-ferritic steels are given in B.2.2 (method 2).
Where test pieces of at least 5 mm wide can not be obtained the material shall not be subject to impact
testing.
Values of the design reference temperature T shall be calculated from the metal temperature T using the
R M
values of the temperature adjustment T given in Table B.2–12.

B.2.1.2 Ferritic steels
Tables B.2–2 to B.2–5 list ferritic steels taken from harmonised European material standards normally used
for low temperature service with an impact test temperature T below – 10 °C.

The tabulated value of T is equated with impact test temperature T for KV = 27J.
