Standard Specification for General Requirements for Wrought Copper and Copper-Alloy Plate, Sheet, Strip, and Rolled Bar (Metric)
Standard Specification for General Requirements for Wrought Copper and Copper-Alloy Plate, Sheet, Strip, and Rolled Bar (Metric)
ABSTRACT This specification establishes the general requirements common to several wrought products including copper and copper-alloy plates, sheets, strips, and rolled bars. The numerical values in this specification are not presented in inch-pound units, but rather, in metric or SI units only. The material for manufacture shall be a cast bar, cake, or slab of such purity and soundness as to be suitable for processing by hot- or cold-working, and annealing to produce a uniform wrought structure in the finished product. The edges shall be slit, sheared, sawed, or rolled, as specified. When rolled edges are required, they may be produced by either rolling or drawing to one of the following specified edge contours: square edges (square corners), rounded corners, rounded edges, and full-rounded edges. Products shall be sampled and prepared, then tested accordingly to examine their conformance to dimensional (thickness, length, width, weight, and straightness), mechanical (tensile and yield strength, Rockwell hardness, and elongation), electrical (resistivity and conductivity), chemical composition, and grain size requirements. SIGNIFICANCE AND USE 11.1 For the purposes of determining compliance with the specified limits for requirements of the properties listed in the following table and for dimensional tolerances, an observed value or a calculated value shall be rounded as indicated in accordance with the rounding method of Practice E29: Property Rounded Unit for Observed or Calculated Value Chemical composition nearest unit in the last Hardness right-hand significant digit Electrical resistivity used in expressing Electrical conductivity the limiting value Tensile strength nearest 5 MPa Yield strength nearest 5 MPa Elongation: nearest 1 % Grain size: Under 0.060 mm nearest multiple of 0.005 mm 0.060 mm and over nearest 0.01 mm SCOPE 1.1 This specification establishes the general requirements common to several wrought product specifications. Unless otherwise specified in the purchase order or in an individual specification, these general requirements shall apply to copper and copper-alloy plate, sheet, strip, and rolled bar supplied under each of the following product specifications issued by ASTM: B36/B36M, B96/B96M, B103/B103M, B121/B121M, B122/B122M, B130, B152/B152M, B169/B169M, B422/B422M, B534, B694, B888/B888M, and B936.2 1.2 Units—This specification is the companion specification to inch-pound Specification B248. 1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
ASTM B248M-22 is the internationally recognized standard from ASTM International that specifies the general requirements for wrought copper and copper-alloy plate, sheet, strip, and rolled bar supplied in metric (SI) units. This standard is critical for manufacturers, suppliers, and buyers in the copper processing industry, providing clear guidelines for the physical, mechanical, and chemical properties that these copper products must meet. ASTM B248M-22 is applicable across various industries where material quality, dimensional tolerances, and product traceability are essential.
