Anodizing of aluminium and its alloys - Check for continuity of thin anodic oxidation coatings - Copper sulfate test (ISO 2085:2018)
This document specifies a method for checking the continuity of thin anodic oxidation coatings on aluminium and its alloys by a copper sulfate contact test.
The use of this method is limited to anodic oxidation coatings of thickness less than 5 µm or coatings that have been deformed, which includes those produced by coil anodizing techniques.
NOTE The method described enables a rapid check to be made for the continuity of a thin coating of aluminium oxidation on aluminium and its alloys. In cases of doubt regarding a visible fault on the surface of a coating, the use of this method makes it possible to verify whether the fault corresponds to a local gap in the coating that exposes bare metal.

Anodisation de l'aluminium et de ses alliages - Contrôle de la continuité des couches anodiques minces - Essai au sulfate de cuivre (ISO 2085:2018)
Le présent document spécifie une méthode de contrôle de la continuité des couches anodiques minces sur l'aluminium et ses alliages par essai au sulfate de cuivre.
L'utilisation de cette méthode est limitée aux couches anodiques de moins de 5 μm d'épaisseur ou à celles ayant subi une déformation, ce qui inclut celles obtenues par des techniques d'anodisation de bandes en continu.
NOTE La méthode décrite permet un contrôle rapide de la continuité de la couche mince d'oxyde sur l'aluminium et ses alliages. Ainsi, en cas de doute sur la présence d'un défaut visible à la surface de la couche, cette méthode permet de vérifier si ce défaut peut correspondre à un manque local de couche laissant le métal à nu.

Ta dokument določa metodo za preverjanje neprekinjenosti tanke anodizirane plasti na aluminiju in aluminijevih zlitinah s kontaktnim preskusom z bakrovim sulfatom.
Uporaba te metode je omejena na anodizirane plasti z debelino manj kot 5 μm ali poškodovanih plasti, kar vključuje plasti, ustvarjene s tehnikami anodizacije tuljave.
OPOMBA: Opisana metoda omogoča hitro preverjanje neprekinjenosti tanke plasti aluminijske oksidacije na aluminiju in aluminijevih zlitinah. V primeru dvoma glede vidne poškodbe na površini plasti je s to metodo mogoče preveriti, ali se poškodba ujema z lokalno odprtino v plasti, ki izpostavlja golo kovino.
General Information

Overview
SIST EN ISO 2085:2018 is an international standard established by CEN that defines a precise method for checking the continuity of thin anodic oxidation coatings on aluminium and its alloys. This standard utilizes the copper sulfate contact test to detect any gaps or discontinuities in anodic oxide layers that are less than 5 µm thick or have been subject to deformation, including coatings created via coil anodizing techniques. The test is valuable for ensuring the protective integrity of anodized aluminium surfaces, critical for corrosion resistance and longevity.
The copper sulfate test provides a rapid, reliable, and simple way to verify coating continuity and detect local defects exposing bare metal, enabling manufacturers and quality control professionals to maintain high standards in surface treatment processes.
Key Topics
Scope and Application
The method applies exclusively to thin anodic oxidation coatings (thickness < 5 µm) or deformed coatings, ensuring targeted inspection of lightweight and sensitive anodized aluminium products.Principle of Testing
Drops of copper sulfate reagent are applied to the aluminium surface. If discontinuities exist, copper deposits chemically on exposed metal, releasing gas rapidly-visible as black or reddish spots or lines indicating coating faults.Reagents and Preparation
A copper sulfate solution is prepared with copper(II) sulfate pentahydrate, hydrochloric acid, and distilled or deionized water. Proper surface cleaning without damaging organic solvents is essential prior to testing for accurate results.Test Area Selection
Sampling involves selecting a flat, horizontal test area approximately 100 mm² within the product surface, avoiding edges and contact points to ensure representative assessment.Testing Procedure
The test is performed at room temperature, applying around four drops of reagent to the defined area, followed by a 5-minute contact time. The surface is then rinsed, and the number, size, and distribution of spots or lines are recorded.Result Interpretation and Reporting
Results are expressed as counts and measurements of defect spots per 100 mm². The test report includes reference to the standard, product identification, observed defects, and any unusual observations made during testing.
Applications
Quality Control in Anodizing Plants
SIST EN ISO 2085:2018 is essential for inspecting thin anodic oxidation coatings during production, particularly in coil anodizing processes where coating uniformity is critical.Corrosion Resistance Assurance
By detecting coating discontinuities early, manufacturers can prevent premature corrosion of aluminium components used in automotive, aerospace, architectural, and electronics industries.Surface Treatment Verification
This standard facilitates routine checks on anodized aluminium parts and assemblies to guarantee surface integrity before assembly or shipment.Deformation Damage Assessment
The test identifies coating breaks caused by mechanical deformation, allowing for timely corrective actions and ensuring product reliability.
