Steel - Conversion of elongation values - Part 2: Austenitic steels (ISO 2566-2:1984)

Specifies a method of converting room temperature percentage elongations after fracture obtained on various proportional and non-proportional gauge lengths to other gauge lengths. The conversions are not applicable to cold reduced steels, quenched and tempered steels and non-austenitic steels, or where certain tensile strength ranges and dimensions are exceeded.

Stahl - Umrechnung von Bruchdehnungswerten - Teil 2: Austenitische Stähle (ISO 2566-2:1984)

Dieser Teil von ISO 2566 legt ein Verfahren für die Umrechnung von prozentualen Dehnungswerten nach erfolgtem Bruch bei Raumtemperatur fest, bei dem Bruchdehnungswerte, die bei verschiedenen proportionalen und nicht-proportionalen Meßlängen ermittelt wurden, auf andere Meßlängen umgerechnet werden. Die Gleichung, die den Umrechnungen zugrunde liegt, gilt als zuverlässig, wenn sie auf rostbeständige austenitische Stähle im Zugfestigkeitsbereich von 450 bis 750 N/mm2 und im lösungsbehandelten Zustand angewendet wird.

Acier - Conversion des valeurs d'allongement - Partie 2: Aciers austénitiques (ISO 2566-2:1984)

Prescrit les exigences à respecter par les fabricants de
transformateurs et d'inductances destinés aux équipements
électroniques afin d'obtenir l'agrément de savoir-faire et définit
les programmes d'essais à effectuer sur les composants pour
l'évaluation de ce savoir-faire.

SIST EN ISO 2566-2:2000
IS0 (the International Organization for Standardization) is a worldwide federation of
national standards bodies (IS0 member bodies). The work of developing International
Standards is carried out through IS0 technical committees. Every member body
- interested in a subject for which a technical committee has been authorized 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.
Draft International Standards adopted by the technical committees are circulated to
the member bodies for approval before their acceptance as International Standards by
the IS0 Council.
International Standard IS0 2566/2 was developed by Technical Committee ISO/TC 17,
Steel, and was circulated to the member bodies in April 1983.
It has been approved by the member bodies of the following countries:
Australia Poland
Austria India Romania
Belgium South Africa, Rep. of
Bulgaria Italy Spain
Canada Tanzania
China Korea, Dem. P. Rep. of Thailand
Czechoslovakia Korea, Rep. of
Finland Mexico United Kingdom
