Corrosion of metals and alloys - Stress corrosion testing - Part 1: General guidance on testing procedures (ISO 7539-1:1987)

Descsribes the general considerations which apply when designing and conducting tests to assess susceptibility of metals to stress corrosion. Particular methods of test are not treated in detail in this document. These are specified in the additional parts of ISO 7539.

Korrosion der Metalle und Legierungen - Prüfung der Spannungsrißkorrosion - Teil 1: Allgemeine Richtlinien für Prüfverfahren (ISO 7539-1:1987)

Dieser Teil von ISO 7539 beschreibt die allgemeinen Betrachtungen für die Planung und Durchführung von Prüfungen zur Beurteilung der Anfälligkeit von Metallen für Spannungsrißkorrosion. Anmerkung: Die einzelnen Verfahren sind in diesem Dokument nicht im Detail behandelt. Diese sind Gegenstand der weiteren Teile von ISO 7539.

Corrosion des métaux et alliages - Essais de corrosion sous contrainte - Partie 1: Guide général des méthodes d'essai (ISO 7539-1:1987)

La présente partie de l'ISO 7539 expose les considérations générales qui s'appliquent à la mise au point et à la réalisation des essais servant à évaluer la sensibilité à la corrosion sous contrainte.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of
national Standards bodies (ISO member bedies). The work of preparing International
Standards is normally carried out through ISO technical committees. Esch 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, govern-
mental and non-governmental, in liaison with ISO, also take part in the work.
Draft International Standards adopted by the technical committees are circulated to
the member bodies for approval before their acceptance as International Standards by
the ISO Council. They are approved in accordance with ISO procedures requiring at
least 75 % approval by the member bodies voting.
International Standard ISO 7539-1 was prepared by Technical Committee ISO/TC 156,
Corrosion of metals and alloys.
Users should note that all International Standards undergo revision from time to time
and that any reference made herein to any other International Standard implies its
latest edition, unless otherwise stated.
