Corrosion of metals and alloys - Stress corrosion testing - Part 5: Preparation and use of C-ring specimens (ISO 7539-5:1989)

Covers procedures for designing, preparing, stressing, exposing and inspecting C-ring specimens. These versatile, economical specimens may be used to test a variety of product forms including parts joined by welding. C-ring specimens may be stressed to predeterminded levels, using simple equipment for application of either constant load or constant strain.

Korrosion der Metalle und Legierungen - Prüfung der Spannungsrißkorrosion - Teil 5: Vorbereitung und Anwendung von C-Ring-Proben (ISO 7539-5:1989)

Der vorliegende Teil von ISO 7539 behandelt Verfahren für die Gestaltung, Vorbereitung, Belastung, Auslagerung und Kontrolle von C-Ring-Proben zur Untersuchung der Anfälligkeit von Metallen für Spannungsrißkorrosion. Eine Analyse der Spannungsart und -verteilung in der C-Ring-Probe wird vorgestellt. In diesem Teil von ISO 7539 werden mit der Benennung "Metall" auch Legierungen erfaßt.

Corrosion des métaux et alliages - Essais de corrosion sous contrainte - Partie 5: Préparation et utilisation des éprouvettes en forme d'anneau en C (ISO 7539-5:1989)

1.1 La présente partie de l'ISO 7539 couvre les procédures de définition, de préparation, de mise sous contrainte, d'exposition et d'examen d'éprouvettes en forme d'anneau en C, servant à évaluer la sensibilité d'un métal à la corrosion sous contrainte. Elle présente une analyse de l'état et de la distribution de la contrainte dans l'anneau en C. Pour les besoins de la présente partie de l'ISO 7539, le terme « métal » inclut également les alliages. 1.2 L'anneau en C constitue une éprouvette économique et polyvalente pour déterminer la sensibilité à la corrosion fissurante sous contrainte de tous les types de métaux entrant dans la composition d'une multitude de formes de produits. Il est particulièrement bien adapté aux essais de tubes, barres et tôles (voir figure 1). Des éprouvettes entaillées peuvent également être utilisées (voir 5.3.8). 1.3 Les éprouvettes en anneau en C peuvent être mises sous contrainte à des niveaux prédéterminés par un équipement simple appliquant une charge ou une déformation croissante.

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. 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. ISO
collaborates closely with the International Electrotechnical Commission (IEC) on all
matters of electrotechnical standardization.
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 7539-5 was prepared by Technical Committee ISO/TC 156,
Corrosion of metals and alloys.
ISO 7539 consists of the following Parts, under the general title Corrosion of metals
and altoys - S tress corrosion tes ting :
-
Part 1: General guidance on testing procedures

Introduction
This part of ISO 7539 is one of a series giving procedures for designing, preparing and
using various forms of test specimen to carry out tests to establish a metals resistance
to stress corrosion.
Esch of the Standards in the series needs to be read in association with ISO 7539-1.
This helps in the choice of an appropriate test procedure to suit particular
circumstances as well as giving guidance towards assessing the significance of the
results of the tests.
