ISO/DIS 6509-2-2014 pdf free.Corrosion of metals and alloys一Determination of dezincification resistance of copper alloys with zinc 一 Part 2: Acceptance criteria. This Part of ISO 6509 specifies acceptance criteria for the selection of dezincification resistant copper alloys with a mass fraction of zinc of more than 15 %, exposed to fresh, saline waters or drinking water. The acceptance criteria are based on the exposure tests in ISO 6509-1. The materials tested and accepted can be in the form of a semi-finished product or in the form of a final product (fittings, valves etc.). This standard 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 standard is not intended to validate dezincification in case of failure in the application. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

ISO 8044-2020 pdf free.Corrosion of metals and alloys 一 Vocabulary. This document defines terms relating to corrosion that are widely used in modern science and technology. In addition, some definitions are supplemented with short explanations. NOTE 1 Throughout the document, IUPAC rules for electrode potential signs are applied. The term metal is also used to include alloys and other metallic materials. NOTE 2 Terms and definitions related to the inorganic surface treatment of metals are given in ISO 2080. 2 Normative references There are no normative references in this document 3 Terms related to corrosion in general ISO and IEC maintain terminological databases for use in standardization at the following addresses: — ISO Online browsing platform: available at https:JJwww.iso.orglobp — IEC Electropedia: available at http://www.electropedia.org/ 3.1 corrosion physicochemical interaction between a metallic material and its environment that results in changes in the properties of the metal, and that may lead to significant impairment of the function of the metal, the environment or the technical system, of which these form a part. Note ito entry: This interaction Is often of an electrochemical nature. 3.2 corrosive agent substance that will initiate or promote corrosion (ii) when in contact with a given metal….
