BS ISO 10074:2017

What is this standard about?

It covers requirements and test methods for hard anodizing – an electrolytic treatment which forms a hard and usually thick coating of alumina, used primarily for engineering purposes. 

This can be applied to cast or wrought aluminium and aluminium alloys. These coatings are mainly used to obtain:

• resistance to wear through abrasion or erosion
• electrical insulation
• thermal insulation
• build-up (to repair parts out of tolerance on machining or worn parts)
• resistance to corrosion (when sealed)

Who is this standard for?

• Anodizers
• Architectural anodizers 
• Producers and manufacturers of building materials, interior fittings, marine equipment, space satellites and automotive parts who will use the standard to specify requirements to the anodizer. 

Why should you use this standard?

It specifies requirements for hard anodic oxidation coatings on aluminium and its alloys, including test methods. It also specifies the information to be supplied by the customer to the anodizer.

NOTE: This standard doesn’t apply to coatings produced by plasma electrolytic oxidation, micro-arc oxidation, plasma-chemical anodic oxidation, anodic spark deposition or spark anodizing.

What’s changed since the last update?

• Normative references have been updated
• The recommended jet nozzle for abrasion testing has been revised
