Anotace textu normy ASTM B248-22 :
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.

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: B19, B36/B36M, B96/B96M, B101, B103/B103M, B121/B121M, B122/B122M, B130, B152/B152M, B169/B169M, B194, B370, B422/B422M, B465, B534, B591, B592, B694, B740, B747, B768, B888/B888M, and B936.2 1.2?UnitsThis specification is the companion specification to SI Specification B248M; therefore, no SI equivalents are shown in this specification. 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. |
