Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out through
ISO technical committees. Each member body interested in a subject for which a technical committee
has been established has the right to be represented on that committee. International organizations,
governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely
with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are described
in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types
of ISO document should be noted. This document was drafted in accordance with the editorial rules of the
ISO/IEC Directives, Part 2 (see www.iso.org/directives).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent
rights in respect thereof. As of the date of publication of this document, ISO had not received notice of (a)
patent(s) which may be required to implement this document. However, implementers are cautioned that
this may not represent the latest information, which may be obtained from the patent database available at
www.iso.org/patents. ISO shall not be held responsible for identifying any or all such patent rights.
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and expressions
related to conformity assessment, as well as information about ISO's adherence to the World Trade
Organization (WTO) principles in the Technical Barriers to Trade (TBT), see www.iso.org/iso/foreword.html.
This document was prepared by Technical Committee ISO/TC 156, Corrosion of metals and alloys, in
collaboration with the European Committee for Standardization (CEN) Technical Committee CEN/TC 262,
Metallic and other inorganic coatings, including for corrosion protection and corrosion testing of metals and
alloys, in accordance with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement).

AMENDMENT 1
4.2.2
Move Table 1 at the end of last paragraph, as follows:
Specimen geometries which are frequently used for corrosion fatigue crack growth rate testing include the
following:
a) three-point single edge notch bend (SENB3);
b) four-point single edge notch bend (SENB4);
c) compact tension (CT);
d) centre-cracked tension (CCT).
Details of standard specimen designs for each of these types of specimen are given in Figures 3 to 6 and
permitted notch geometries are given in Figure 7. Suitable machining tolerances are given in Table 1.
Table 1 — Dimensions of specimens with tolerances
Dimension Tolerances Surface finish, squareness and parallelism
L Surfaces shall be perpendicular and parallel as applicable to
within 0,002 W (Total indicator reading)
G
H Surface finish of faces perpendicular to the line of the notch root
to be Ra 0,8 µm
±0,01 W
F
F ±0,004 W Notch to be equidistant about centre-line to within 0,01 W
Holes to be square to faces within ±0,007 5 W and parallel
D +0,004 W within ±0,000 5 W
Surface finish Ra 0,4 µm
4.2.3
Move Table 2 to Table 5 at the end of last paragraph, as follows:
The values of Y appropriate to the four specimen geometries discussed above are given in Tables 2 to 5.
