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.
In exceptional circumstances, when a technical committee has collected data of a different kind from that
which is normally published as an International Standard (“state of the art”, for example), it may decide by a
simple majority vote of its participating members to publish a Technical Report. A Technical Report is entirely
informative in nature and does not have to be reviewed until the data it provides are considered to be no
longer valid or useful.
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.
ISO/TR 20173 was prepared by Technical Committee ISO/TC 44, Welding and allied processes,
Subcommittee SC 10, Unification of requirements in the field of metal welding.
This second edition cancels and replaces the first edition (ISO/TR 20173:2005), which has been technically
revised.
Requests for official interpretations of any aspect of this Technical Report should be directed to the Secretariat
of ISO/TC 44/SC 10 via your national standards body. A complete listing of these bodies can be found at

Avant-propos
L'ISO (Organisation internationale de normalisation) est une fédération mondiale d'organismes nationaux de
normalisation (comités membres de l'ISO). L'élaboration des Normes internationales est en général confiée
aux comités techniques de l'ISO. Chaque comité membre intéressé par une étude a le droit de faire partie du
comité technique créé à cet effet. Les organisations internationales, gouvernementales et non
gouvernementales, en liaison avec l'ISO participent également aux travaux. L'ISO collabore étroitement avec
la Commission électrotechnique internationale (CEI) en ce qui concerne la normalisation électrotechnique.
Les Normes internationales sont rédigées conformément aux règles données dans les Directives ISO/CEI,
Partie 2.
La tâche principale des comités techniques est d'élaborer les Normes internationales. Les projets de Normes
internationales adoptés par les comités techniques sont soumis aux comités membres pour vote. Leur
publication comme Normes internationales requiert l'approbation de 75 % au moins des comités membres
votants.
Exceptionnellement, lorsqu'un comité technique a réuni des données de nature différente de celles qui sont
normalement publiées comme Normes internationales (ceci pouvant comprendre des informations sur l'état
de la technique par exemple), il peut décider, à la majorité simple de ses membres, de publier un Rapport
technique. Les Rapports techniques sont de nature purement informative et ne doivent pas nécessairement
être révisés avant que les données fournies ne soient plus jugées valables ou utiles.
L'attention est appelée sur le fait que certains des éléments du présent document peuvent faire l'objet de
droits de propriété intellectuelle ou de droits analogues. L'ISO ne saurait être tenue pour responsable de ne
pas avoir identifié de tels droits de propriété et averti de leur existence.
L'ISO/TR 20173 a été élaboré par le comité technique ISO/TC 44, Soudage et techniques connexes,
sous-comité SC 10, Unification des prescriptions dans la technique du soudage des métaux.
Cette deuxième édition annule et remplace la première édition (ISO/TR 20173:2005), qui a fait l'objet d'une
révision technique.
Il convient d'adresser les demandes d'interprétation officielles de l'un quelconque des aspects du présent
Rapport technique au secrétariat de l'ISO/TC 44/SC 10 via votre organisme national de normalisation. La liste
exhaustive de ces organismes peut être trouvée à l'adresse http://www.iso.org.

RAPPORT TECHNIQUE ISO/TR 20173:2009(F)

Soudage — Systèmes de groupement des matériaux —
Matériaux américains
1 Domaine d'application
Le présent Rapport technique fournit un système de groupement américain des matériaux destinés au
[1]
soudage, classés conformément au système de groupement de l'ISO/TR 15608:2005 .
Il peut également s'appliquer pour d'autres fins, tels le traitement thermique, le formage et les contrôles non
destructifs. Les types d'acier sont énumérés conformément au système de groupement de
l'ISO/TR 15608:2005, Tableau 1.
Le présent Rapport technique couvre les systèmes de groupement des matériaux normalisés suivants:
⎯ aciers;
⎯ aluminium et alliages d'aluminium;
⎯ nickel et alliages de nickel;
⎯ cuivre et alliages de cuivre;
⎯ titane et alliages de titane;
⎯ zirconium et alliages de zirconium;
⎯ fontes.
