Annotation of standard text ASTM B187/B187M-26a :

This specification establishes the requirements for copper conductor bars, rods, and shapes for both electrical (bus) and general applications. Products shall be produced in tempers O60 (soft annealed), and H04 (hard). Products shall be sampled and prepared, then tested accordingly to examine their conformance to dimensional (mass, diameter, thickness, width, shape, specified and stock lengths, straightness, edge contour, and radius of edges or corners), mechanical (tensile, yield and bend strengths, elongation, Rockwell hardness, and embrittlement), electrical resistivity, and chemical composition requirements.
