Corrosion of metals and alloys - Determination of dezincification resistance of copper alloys with zinc - Part 1: Test method (ISO 6509-1:2014)

ISO 6509-1:2014 specifies a method for the determination of dezincification depth of copper alloys with zinc exposed to fresh, saline waters or drinking water. The method is intended for copper alloys with a mass fraction of zinc more than 15 %.
ISO 6509-1:2014 describes only the test methodology and does not set out criteria for acceptability of materials for a specific application. Acceptance criteria are described in ISO 6509‑2.

Dieser Teil von ISO 6509 legt ein Verfahren zur Bestimmung der Entzinkungstiefe von Kupfer-Zink-Legierungen, die Wasser, salzhaltigen wässrigen Lösungen oder Trinkwasser ausgesetzt werden, fest. Das Verfahren ist für Kupfer Zink Legierungen vorgesehen, die einen Massenanteil an Zink von mehr als 15 % aufweisen.
Dieser Teil von ISO 6509 beschreibt nur das Prüfverfahren und legt keine Akzeptanz¬kriterien von Werkstoffen für eine spezifische Anwendung fest. Die Akzeptanzkriterien werden in ISO 6509 2 beschrieben.
ANMERKUNG   Das Verfahren darf außerhalb des Anwendungsbereiches im Rahmen einer Überprüfung oder zu Forschungszwecken angewendet werden.

Corrosion des métaux et alliages - Détermination de la résistance à la dézincification des alliages de cuivre avec le zinc - Partie 1: Méthode d'essai (ISO 6509-1:2014)

L'ISO 6509-1:2014 spécifie une méthode permettant de déterminer la profondeur de dézincification du cuivre allié avec le zinc, exposé aux eaux douces ou salées, ou à l'eau potable. Cette méthode est applicable aux alliages de cuivre ayant une fraction massique en zinc supérieure à 15 %.
L'ISO 6509-1:2014 décrit uniquement la méthodologie d'essai et n'indique pas les critères d'acceptabilité des matériaux dans le cadre d'une application spécifique. Les critères d'acceptation sont décrits dans l'ISO 6509 2.

EN ISO 6509-1 navaja metodo za ugotavljanje odpornosti razcinkanja bakrovih zlitin s cinkom, izpostavljenih sladki oziroma slani ali pitni vodi. Ta metoda je namenjena za bakrove zlitine z masnim deležem, višjim od 15 %. Ta del standarda ISO 6509 opisuje samo preskusno metodologijo in ne navaja meril za sprejemljivost materialov za določeno uporabo. Merila sprejemljivosti so podrobneje opisana v standardu ISO 6509-2.

Overview

EN ISO 6509-1:2014 - "Corrosion of metals and alloys - Determination of dezincification resistance of copper alloys with zinc - Part 1: Test method" is a CEN-adopted ISO test method for measuring dezincification depth in copper‑zinc alloys (zinc mass fraction > 15 %) after exposure to fresh water, saline water or drinking water. The standard defines specimen preparation, test solution and exposure conditions, and microscopic measurement procedures. It describes only the test methodology; acceptance criteria are provided in ISO 6509‑2.

Key topics and technical requirements

• Scope: Applies to copper alloys with >15 % zinc exposed to potable, fresh or saline waters.
• Test principle: Immersion in a copper(II) chloride solution followed by microscopic examination of cross‑sections to measure dezincification depth.
• Reagents & materials:
  • Copper(II) chloride 1 % solution (preparation details given).
  • Deionized water (conductivity ≤ 20 µS/cm at 25 °C).
  • Non‑conductive embedding material (e.g., phenolic resin) and suitable solvents for cleaning.
• Apparatus & conditions:
  • Thermostatically controlled environment maintaining 75 °C ± 5 °C during exposure.
  • Glass beaker sealed with non‑metallic cover; specimens positioned vertically and elevated above the beaker bottom.
• Specimen preparation:
  • Embedded and ground test surfaces finished with 500‑grade abrasive paper or finer; selection of specimens from representative product areas (thin/thick sections, extrusion/rolling directions).
• Exposure & examination:
  • Continuous immersion (standard exposure time ~24 h with tolerance specified in the standard).
  • After exposure, specimens are washed, solvent‑rinsed, sectioned perpendicular to the test surface, polished and examined microscopically.
  • Record maximum and average dezincification depth; characterize distribution (localized vs. layer dezincification) and phase‑specific attack where relevant.

Practical applications and users

• Who uses this standard:
  • Materials and corrosion testing laboratories performing qualification and quality control tests.
  • Manufacturers of brass and copper‑zinc components (valves, fittings, plumbing, marine hardware).
  • Product designers, corrosion engineers and standards bodies specifying material suitability for water applications.
• Why it’s useful:
  • Provides a reproducible laboratory method to quantify dezincification susceptibility, supporting material selection, failure investigation and product development.
  • When combined with ISO 6509‑2 (acceptance criteria), it supports pass/fail decisions for specific applications.

Related standards

• ISO 6509‑2 - Acceptance criteria (companion document).
• ISO 8044 - Corrosion of metals and alloys - Basic terms and definitions.
• Referenced test practice example: ASTM F21–65 (for solvent‑cleaning efficacy; see standard text).

Keywords: dezincification, copper alloys, corrosion testing, ISO 6509-1:2014, dezincification resistance, copper(II) chloride test, plumbing materials, brass testing.
