BS ISO 6509-2:2017

This standard BS ISO 6509-2:2017 Corrosion of metals and alloys. Determination of dezincification resistance of copper alloys with zinc is classified in these ICS categories:

• 77.060 Corrosion of metals

This document 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.).

This document 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.
