BS EN 2133:2020

What is BS EN 2133 about?  

BS EN 2133 specifies the electrolytic cadmium plating of parts and fasteners in steel of tensile strength UTS ≤ 1 450 MPa, copper, copper alloys and nickel alloys, whose temperature is in service does not exceed 235 °C. 

Who is BS EN 2133 for? 

BS EN 2133 on cadmium plating of steels is applicable to: 

• Aerospace and Defence industries 
• Agencies involved in making aerospace applications 
• Spacecraft manufacturing industries 
• Testing agencies involved in the inspection of aerospace products 
• Welders and Fabricators 

Why should you use BS EN 2133? 

To enhance the performance of the overall aerospace applications and avoid product failure, the quality and durability of steel used is a critical factor. 

BS EN 2133 covers all the requirements for cadmium plating of steels. It creates a standardized approach for manufacturers of cadmium plating of steels to adhere to if they supply their metallic materials for use in the aerospace and defence industry. 

By adopting BS EN 2133, manufacturers can demonstrate the reliability of their cadmium plating of steels and build trust in its use throughout the aerospace supply chain. 

The purpose of the processes in BS EN 2133 is to ensure protection against corrosion or to reduce the effects of galvanic coupling when assembling different materials. 

What’s changed since the last update?  

BS EN 2133:2020 supersedes BS EN 2133:2010. BS EN 2133:2020 includes some technical changes with respect to BS EN 2133:2010. These include: 

• Requirements for finishing operations other than chromating, e.g. phosphating" has been replaced by "Requirements for finishing operations other than Type 2 or Type 3 post-treatment, e.g. phosphating" 
• In process schedule addition of a process flow chart
