Corrosion of metals and alloys. Determination of dezincification resistance of copper alloys with zinc - Assessment criteria1 Scope 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 65091. The materials can be in the form of a semi finished product or in the form of a final product (fittings, valves, etc.). This

field sampling programmes can differ and are not necessarily covered here
