What is this standard about?

It supplies technical specifications designed to ensure that copper ingots and castings are produced in line with industry requirements. It also recommends that a full consultation takes place between the purchaser and the supplier at the enquiry and ordering stages.

The standard covers:

• Copper alloy ingots intended to be re-melted for later processing (e.g. castings)
• Copper and copper alloy castings intended for use without subsequent working, other than machining

Who is this standard for?

It 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
• Users of these products
• Copper technology centres and R&D laboratories
• Standard suppliers and standard management companies

Why should you use this standard?

Because it 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?

The standard has been extensively revised. The following significant changes have been made:

• Introduction of a clear distinction between ingots and castings with regard to 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

Other changes in the standard are:

• Rearrangement 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 following 16 new materials: CB773S and CC773S (new Table F.4), CB757S and CC757S (new Table G.8), CB768S and CC768S (new Table H.2), CB770S and CC770S (new Table G.4), CB771S and CC771S (new Table F.1), CB772S and CC772S (new Table G.9) CB245E and CC245E (new Table P.1) as well as CB246E and CC246E (new Table P.2)
• Addition of 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 with regard to pressure equipment applications in 6.2.1 “Ingots” and 6.2.2 “Castings” 
• Revision of Clauses 5 i), 6.1, 6.4, 6.5 and 8.2.3
• Indication that mechanical properties for the “Pressure die cast – GP” castings are mandatory
• Amendment of Table ZA.1
• Deletion of B.5
• Several editorial amendments
