Full title and description

ISO 10215:2018 — Anodizing of aluminium and its alloys — Visual determination of image clarity of anodic oxidation coatings — Chart scale method. This International Standard defines a simple visual procedure using a chart (grid) scale and a lightness scale to assess the image clarity (clearness, distortion and haze) of anodic oxide coatings on flat aluminium surfaces.

Abstract

Specifies a visual method for determining the image clarity of anodic oxidation coatings on aluminium and its alloys by comparing reflected images of a defined chart scale and using a lightness scale. The method is intended for flat surfaces capable of reflecting the chart pattern and is intended for quality control and inspection of anodic coatings.

Scope

Gives a visual test method to assess the image clarity of anodic oxidation (anodized) coatings on aluminium and aluminium alloys by observing reflected images of a calibrated chart (grid) and using a defined lightness scale; applicable only to flat, reflective surfaces. The procedure covers apparatus, specimen preparation, test procedure, expression of results and reporting.

Key topics and requirements

• Definition and use of a chart (grid) scale and a lightness scale for visual assessment.
• Requirements for test specimen preparation and surface flatness/reflectivity.
• Apparatus and lighting/observation conditions for repeatable visual comparison.
• Assessment criteria for image clearness, distortion and haze and rules for expressing results.
• Minimum reporting content for test results and any deviations from the method.

Typical use and users

Used by anodizing plants, surface-treatment quality-control laboratories, metal finishers, product designers and specifiers, inspection bodies and procurement teams to evaluate and document the optical quality (image clarity) of anodic oxide coatings on flat aluminium components.

Related standards

Standards in the same ISO technical area include ISO 10216 (instrumental determination of image clarity — instrumental method) and ISO 7583 (terms and definitions for anodizing of aluminium). These complementary standards cover instrumental measurement approaches and standardized terminology used alongside ISO 10215.

Q: What does it cover?

A: It covers the principle, required apparatus, specimen preparation, test procedure, how to express results and what to include in the test report for visual determination of image clarity (clearness, distortion and haze) using a defined chart and lightness scale.

Q: Who typically uses it?

A: Manufacturers and processors of anodized aluminium, independent test laboratories, inspection and quality departments, specifiers, and purchasing/acceptance inspectors who need a repeatable visual method to assess coating optical quality.

Q: Is it current or superseded?

A: The 2018 edition (Edition 3) is published and was reviewed and confirmed as current during ISO’s systematic review (confirmation recorded in 2023).
