Overview
ISO 197-3:1983, titled Copper and copper Alloys - Terms and Definitions - Part 3: Wrought Products, is an International Standard developed by ISO Technical Committee ISO/TC 26. This standard specifically defines terminology related to wrought copper and copper alloy products, which are formed by hot and/or cold plastic deformation processes. These processes include extruding, forging, hot rolling, cold rolling, and drawing.
The standard covers a broad range of wrought products such as rods, bars, wire, drawing stock, tubes, profiles, sheets, strips, foils, forging stock, blanks, circles, and slugs. It not only standardizes the vocabulary but also clarifies classification principles through an annex, promoting consistency within the global copper industry and trade.
Key Topics
- Wrought Products: Defined as copper and copper alloy products manufactured by plastic deformation processes, either hot or cold, or a combination of both.
- Product Types and Definitions:
- Rod/Bar: Solid products with uniform cross-section, supplied straight; cross-sections include circular, oval, square, rectangular, triangular, or regular polygonal shapes.
- Wire: Solid uniform cross-section products supplied in coils, with cross-sections similar to rods/bars but distinguishable by supply form.
- Drawing Stock (Wire Rod): Intermediate coil products with cross-sections generally round, triangular, or polygonal, intended for subsequent drawing.
- Tube: Hollow products with a single enclosed void and uniform wall thickness, supplied either straight or coiled.
- Profile: Products with uniform cross-section excluding rods, bars, wire, tubes, sheets, or strips, supplied either coiled or straight; differentiated into hollow and solid profiles.
- Sheet, Strip, Foil: Flat rolled products differing mainly by thickness and form of delivery; sheets and strips have thickness ≥ 0.10 mm (sheets are straight, strips are coiled), foil is less than 0.10 mm and supplied flat or coiled.
- Forging Stock: Hot-worked intermediate products suitable for forging, sometimes cast like billets.
- Forging: Products formed by hammering or pressing, usually hot, either between open or closed dies.
- Blank, Circle, Slug: Defined shapes used for further processing or specific forming operations like impact extrusion.
Applications
ISO 197-3:1983 is invaluable for manufacturers, traders, and users of copper and copper alloy wrought products who require consistent terminology across international markets. Its applications include:
- International Trade and Customs: The definitions align with the Customs Co-operation Council’s Harmonized Commodity Description and Coding System, facilitating standardized declarations and smoother import/export procedures.
- Quality Control: Clear product definitions help in establishing precise specifications for material procurement and manufacturing processes.
- Design and Engineering: Engineers and designers rely on these terms to communicate exact product types, shapes, and dimensions in drawings and specifications.
- Manufacturing: Producers utilize the terminology to classify products accurately and to ensure compliance with international standards during production and testing.
Related Standards
ISO 197-3:1983 complements other parts of the ISO 197 series that cover different aspects of copper and copper alloys:
- ISO 197-1: Terms and definitions related to cast products
- ISO 197-2: Terms and definitions related to semi-finished rolled products
- ISO/TR 197/3-1976: The earlier technical report replaced by this revised standard
In addition, ISO 197-3 interfaces with global commodity standards and harmonized classification systems, supporting uniform terminology usage worldwide.
