What is BS EN 1982 about?
BS EN 1982 is a European standard on copper ingots and castings that discusses the criteria for casting and manufacturing copper ingots. BS EN 1982 specifies the composition, mechanical properties, and other relevant characteristics of copper and copper alloys. The sampling procedures and test methods for the verification of conformity to the requirements of this standard are also specified.
BS EN 1982 applies to:
- Copper alloy ingots intended to be remelted for later processing (e.g. castings); and
- Copper and copper alloy castings that are intended for use without subsequent working other than machining.
Recommended practice for the ordering and supply of castings is included in Annex A. Optional supplementary inspection procedures for ingots and castings are included in Annex B.
NOTE: Ingots are not suitable for pressure equipment applications.
Who is BS EN 1982 for?
BS EN 1982 on copper and copper alloys applies to commercial producers, suppliers, and users of copper and copper alloy, specifically:
- Foundries responsible for the production of copper and copper alloy ingots or copper castings for mechanical applications
- Manufacturers of copper and copper alloy products – ingots and castings
- Suppliers of these products, particularly stockists
- Copper technology centers and R&D laboratories
Why should you use BS EN 1982?
A copper ingot is a piece of relatively pure material, usually metal, that is cast into a shape suitable for further processing.
BS EN 1982 provides the best guidance on ingots, castings their mechanical properties, electrical properties, microstructure, and grain size, dezincification resistance, sampling and testing frequency, and test methods
BS EN 1982 reflects current industry and market practices and its use ensures that:
- Raw materials are of the quality customers demand
- Producers can streamline their manufacturing processes, saving time and money
- Suppliers will always deliver to the purchaser’s precise requirements
- Products consistently meet and exceed quality assurance targets
What’s changed since the last update?
BS EN 1982 supersedes BS EN 1982:2008, which is withdrawn.
In comparison with EN 1982:2008, the following significant changes were made:
- Introduction of a clear distinction between ingots and castings about pressure equipment applications in the whole standard
- Addition of information concerning pressure equipment application to the introduction and to the scope, addition of information concerning materials that can be used for products in contact with drinking water in tables f.1, f.4, g.4, g.8, g.9, h.2, k.2, p.1 and p.2
- Rearrangements of the tables giving the chemical compositions and mechanical properties of the materials which were moved from clause 6 to annex c to annex p
- Addition of the 16 new materials and the terms “ingot” and “casting” and their definitions in clause 3
- Deletion of item o) in clause 5 “ordering information” and renumbering of the subsequent items
- Subdivision between ingots and castings about pressure equipment applications in 6.2.1 “ingots” and 6.2.2 “castings”
- Indication that mechanical properties for the “pressure die-cast – GP” castings are mandatory
