ISO 24394:2008/Amd.1:2012(E)
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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International
Standards adopted by the technical committees are circulated to the member bodies for voting.
Publication as an International Standard requires approval by at least 75 % of the member bodies
casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights.
Amendment 1 to ISO 24394:2008 was prepared by Technical Committee ISO/TC 44, Welding and
allied processes.
This corrected version of ISO 24394/Amd.1:2012 incorporates an updated Table 1, in which “x” replaces
“—” for D > 26 mm in:
a) TP1, PF row, butt weld columns PA and PF;
b) TP2, PF row, fillet weld column PF;
c) TP3, PF row, butt weld columns PA, PE, and PF.
Requests for official interpretations of any aspect of this amendment should be directed to the Secretariat of
ISO/TC 44 via your national standards body. A complete listing of these bodies can be found at www.iso.org.
