Anodizing of aluminium and its alloys - Method for specifying decorative and protective anodic oxidation coatings on aluminium (ISO 7599:2018)
Anodizing of aluminium and its alloys - Method for specifying decorative and protective anodic oxidation coatings on aluminium (ISO 7599:2018)
ISO 7599:2018 specifies a method for specifying decorative and protective anodic oxidation coatings on aluminium (including aluminium-based alloys). It defines the characteristic properties of anodic oxidation coatings, lists methods of test for checking the characteristic properties, provides minimum performance requirements, and gives information on the grades of aluminium suitable for anodizing and the importance of pretreatment to ensure the required appearance or texture of the finished work. It is not applicable to a) non-porous anodic oxidation coatings of the barrier layer type, b) anodic oxidation coatings produced by chromic acid or phosphoric acid anodizing, c) anodic oxidation coatings intended merely to prepare the substrate for subsequent application of organic coatings or for the electrodeposition of metals, and d) hard anodic oxidation coatings used mainly for engineering purposes, for which abrasion and wear resistance are the primary characteristics (see ISO 10074).
EN ISO 7599:2018 - "Anodizing of aluminium and its alloys - Method for specifying decorative and protective anodic oxidation coatings on aluminium" (ISO 7599:2018) is a CEN-endorsed international standard that defines how to specify, test and accept decorative and protective anodic oxide coatings on aluminium and aluminium alloys. It defines characteristic properties, test methods, minimum performance requirements, suitable aluminium grades and the role of pretreatment to achieve required appearance or texture. The standard does not apply to barrier (non‑porous) anodic coatings, chromic/phosphoric anodizing processes, coatings intended solely as primers for organic finishes or electrodeposition, or hard anodic coatings primarily for wear resistance (see ISO 10074).
