Overview
ISO 7583:2013 - Anodizing of aluminium and its alloys - Terms and definitions is an international terminology standard that defines vocabulary used in the anodizing of aluminium. The second edition (2013) revises the original 1986 edition and provides consistent, industry‑wide definitions covering anodized aluminium products, processes, surface finishes, pretreatments, oxide morphology, colouring, sealing, process control, defects, tests and performance characteristics. Use of this standard helps ensure unambiguous communication in specifications, procurement, testing and quality control.
Key Topics
The standard organizes terms into concise subject groups, including:
- Anodized aluminium products: e.g., architectural anodizing, bright anodized, hard anodized, type I/II/III anodized aluminium, coil and batch anodizing.
- Finishes: matt, satin, scratch‑brushed and texture descriptors.
- Pretreatments: cleaning, degreasing, etching, brightening, desmutting, electrograining and related surface preparation terms.
- Anodic oxidation processes: anodizing types (d.c., a.c.), chromic, sulfuric and phosphoric acid processes, plasma (PEO/MAO) and barrier film anodizing.
- Anodic aluminium oxide (AAO): anodic oxidation coating, barrier layer, pore, oxide cell, porosity and porous layer morphology.
- Colouring and sealing: dyed, electrolytic colouring, fixation, bleaching, cold/hydrothermal/steam sealing, sealing smut and intermediate layer.
- Process control and testing: terms describing anodizing efficiency, operation, defects, tests and properties relevant to performance and inspection.
Applications and Who Uses It
ISO 7583:2013 is practical for anyone who specifies, produces, inspects or uses anodized aluminium:
- Surface treatment and anodizing plants - for consistent process descriptions and quality documentation.
- Design engineers and product developers - to ensure materials and finishes are correctly specified.
- Architects and façade consultants - for architectural anodizing terminology in building specifications.
- Aerospace and electronics industries - where chromic acid anodizing, barrier films and pretreatments are referenced.
- Quality inspectors, test labs and procurement teams - to remove ambiguity in contracts, test reports and colour/finish limits.
- Nanotechnology and research - AAO terminology supports work on porous anodic oxide applications.
Related Standards
- Developed by ISO/TC 79 (Light metals and their alloys), this edition supersedes ISO 7583:1986.
- Use together with process, test and performance standards for anodizing, coating and corrosion testing when preparing technical specifications or quality plans.
