ISO 6509-2:2017

Corrosion of metals and alloys — Determination of dezincification resistance of copper alloys with zinc — Part 2: Assessment criteria

ISO 6509-2:2017 specifies assessment criteria and provides guidance related to the corrosion type dezincification for the selection of copper alloys with a mass fraction of zinc of more than 15 %, exposed to fresh, saline waters or drinking water. The assessment criteria are based on the exposure tests in ISO 6509‑1. The materials can be in the form of a semi-finished product or in the form of a final product (fittings, valves, etc.). ISO 6509-2:2017 is not applicable to complex products like flow-meters or pump-parts. In addition, other properties of the material might need to be taken into account for the intended application. This document is not intended to validate dezincification in case of failure in the application.

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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).
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. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www .iso .org/ patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

expressions related to conformity assessment, as well as information about ISO’s adherence to the
World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT) see the following

This document was prepared by Technical Committee ISO/TC 156, Corrosion of metals and alloys.
This first edition of ISO 6509-2 cancels and replaces ISO 6509:1981, which has been technically revised.
