BS EN 12449:2016+A1:2019

What is BS EN 12449- Copper and copper alloys about?  

BS EN 12449 is a European standard on copper and copper alloys that discusses the best procedures and specifications required for manufacturing high-quality seamless copper and copper alloy tubes. BS EN 12449 specifies the composition, property requirements, and tolerances on dimensions and form for seamless round drawn copper and copper alloy tubes for general purposes supplied in the size range from 3 mm up to and including 450 mm outside diameter and from 0,3 mm up to and including 20 mm wall thickness. 

The sampling procedures and the methods of test for verification of conformity to the requirements of BS EN 12449 are also specified. 

NOTE: Tubes having an outside diameter less than 80 mm and/or a wall thickness greater than 2 mm in certain alloys are most frequently used for free machining purposes which are specified in EN 12168. 

Who is BS EN 12449- Copper and copper alloys for?  

BS EN 12449 on copper and copper alloys is relevant to: 

• Manufacturer of seamless copper and copper alloy tubes  

Why should you use BS EN 12449- Copper and copper alloys? 

A seamless tube is a tube that does not have any welding seam. The seamless tube will ideally be a solid metal tube with each end connected to another tube without having any welding joint. 

BS EN 12449 provides guidance on mechanical properties, dimensions, and tolerances, outside or inside diameter, wall thickness, surface quality, analysis, tensile, hardness, drift expanding, and grain size tests. 

BS EN 12449 exemplifies the required composition of copper and copper alloy that help you achieve precision in terms of product quality. 

As a user of BS EN 12449, you can be ensured of composition, property requirements, and tolerances on dimensions and form for seamless copper tube. With obedience and compliance to BS EN 12449, you can efficiently manufacture high-quality seamless, round copper and copper alloy tubes. BS EN 12449 helps you achieve precision in terms of products specification. With BS EN 12449 you can be ensured that the products consistently meet and exceed quality assurance targets. 

What’s changed since the last update?  

BS EN 12449:2016+A1:2019 supersedes BS EN 12449:2016, which is withdrawn. 

In comparison with EN 12449:2012, the following significant technical changes were made: 

• Addition of the new material CuFe0,1Sn0,1P (CW125C) 
• Modification of the elongation values for Cu-DHP (CW024A) in material condition R250 including new Table 16; 
• Modification of iron and tin content for CuZn37Pb1 (CW605N) from 0,2 % to 0,3 % in Table 7 
• Replacement of the material number CW121C by CW124C for CuSi3Zn2P
