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.

The article discusses SIST EN ISO 6509-1:2014, a standard that provides a method for measuring the dezincification depth of copper alloys with zinc when exposed to fresh, saline waters or drinking water. This standard applies to copper alloys with a zinc content of more than 15%. It is important to note that this part of ISO 6509 only outlines the testing procedure and does not establish criteria for determining if materials are acceptable for a particular application. The acceptance criteria can be found in ISO 6509-2.
