What is BS EN 12168 - Copper alloy hollow rod about?
BS EN 12168 is a European standard on copper alloy hollow rods that discusses the criteria for manufacturing high-quality and precise hollow rods. BS EN 12168 specifies the composition, property requirements, and dimensional tolerances for copper alloy hollow rod, finally produced by drawing or extruding, specifically intended for free machining purposes.
The sampling procedures, the methods of test for verification of conformity to the requirements of this BS EN 12168, are also specified.
NOTE: Hollow products having an outside diameter greater than 80 mm and/or a wall thickness less than 2 mm are specified in EN 12449.
Who is BS EN 12168 - Copper alloy hollow rod for?
BS EN 12168 on copper and copper alloy hollow rod is relevant to:
- Manufacturer of copper and copper alloys hollow rod
Why should you use BS EN 12168 - Copper alloy hollow rod?
A hollow bar has the strength of a solid round bar, but since there is no center, there is less weight per foot which can sometimes save money, without compromising strength.
BS EN 12168 provides guidance on designations, material condition, mechanical properties, chemical composition, dimension and tolerance, dezincification resistance and stress corrosion resistance tests, surface quality, sampling, and test method.
BS EN 12168 exemplifies the required dimension and tolerance, mechanical properties, chemical composition that help you achieve precision in terms of product functionality and specification. With obedience and compliance to BS EN 12168, you can efficiently manufacture high-quality copper and copper alloy hollow rods with precise tolerances, dimensions, and shapes. BS EN 12168 provides you with comprehensive information useful throughout the process of production.
What’s changed since the last update?
BS EN 12168:2016 supersedes BS EN 12168:2011 which is withdrawn.
In comparison with EN 12168:2011, the following significant technical changes were made:
- Addition of four new materials: CuZn37Pb1 (CW605N), CuZn35Pb1,5AlAs (CW625N), CuZn33Pb1,5AlAs (CW626N), and CuZn33Pb1AlSiAs (CW725R) due to the market requirements on the restriction of lead and modification of the chemical composition for CuZn39Pb1 (CW611N)
- Introduction of an optional procedure how to refer to restrictions to the chemical composition imposed by the 4 MS Common Composition List for materials used for products accepted for contact with drinking water
- Requirements and test methods for resistance of dezincification modified
- Provisions for surface quality added
- Mechanical properties for CuZn21Si3P (CW724R) modified
