Corrosion of metals and alloys - Determination of dezincification resistance of brass (ISO 6509:1981)

The method applies to brass exposed to frech or saline waters. May be used for control or research purposes, but the field of application is not specified. The method consists of exposure of test pieces to copper(II) chloride solution followed by microscopic examination.

Korrosion von Metallen und Legierungen - Bestimmung der Entzinkungsbeständigkeit von Kupfer-Zink-Legierungen (ISO 6509:1981)

Die vorliegende Internationale Norm beschreibt ein Verfahren zur Bestimmung der Entzinkungsbeständigkeit von Kupfer-Zink-Legierungen, die Wasser oder salzhaltigen wässrigen Lösungen ausgesetzt werden. Das Verfahren kann im Rahmen einer Überprüfung oder zu Forschungßwecken verwendet werden, das Anwendungsgebiet ist jedoch nicht festgelegt.

Foreword

ISO (the International Organization for Standardization) is a worldwide federation of

national Standards institutes (ISO member bedies). The work of developing Inter-

national Standards is carried out through ISO technical committees. Every member -

body interested in a subject for which a technical committee has been set up has the

right to be represented on that committee. Inteinational organizations, governmental

and non-governmental, in Iiaison 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.
International Standard ISO 6509 was developed by Technical Committee ISO/TC 156,
Corrosion of metals and atloys, and was circulated to the member bodies in
February 1980.
lt has been approved by the member bodies of the following countries :
