BS EN 4704:2012

What is BS EN 4704 – Tartaric-Sulphuric-Acid anodizing of aluminium and aluminium wrought alloys about?

BS EN 4704 discusses aluminium and aluminium wrought alloys. The purpose of BS EN 4704 is to give design and quality requirements to manufacturers.

BS EN 4704 defines the requirement for Tartaric-Sulphuric-Acid (TSA) anodizing of aluminium

and wrought alloys for corrosion protection and paint pre-treatment.

Who BS EN 4704 - Tartaric-Sulphuric-Acid anodizing of aluminium and aluminium wrought alloys for? 

BS EN 4704 on Tartaric-Sulphuric-Acid anodizing of aluminium and aluminium wrought alloys is useful for: 

• Aerospace equipment and component manufacturers
• Aluminium and aluminium wrought alloys manufacturers
• Product design engineers
• Quality control, testing and inspection authorities
• Regulatory bodies
• Certification bodies

Why should you use BS EN 4704 - Tartaric-Sulphuric-Acid anodizing of aluminium and aluminium wrought alloys?  

TSA process is an electrochemical process used for generating an aluminium oxide layer for corrosion protection and surface treatment prior to the application of a corrosion-inhibiting primer. However, anodizing does not increase the strength of the aluminium object. The anodic layer is insulative. When it comes to the manufacturing and use of aerospace components, reliability, consistent performance, and durability are crucial.

BS EN 4704 walks you through the technical, engineering and quality requirements anodizing of aluminium and aluminium wrought alloys. This will ensure the quality and performance of anodizing of aluminium and aluminium wrought alloys. 

With compliance to BS EN 4704 you can demonstrate the reliability of anodizing of aluminium and aluminium wrought alloys and build trust in their use throughout the aerospace supply chain.
