Anotácia textu normy ASTM B569-24 :

This specification establishes the requirements for brass strips in narrow widths and light gages produced from Copper Alloy UNS Nos. C23000, C26000, and C26130 to be used in heat exchanger tubing. 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 working, cold working, and annealing to produce a uniform wrought structure in the finished product. Products shall be produced in tempers H01 (? hard), H02 (? hard), O81 (annealed-to-temper, ? hard), and O82 (annealed-to-temper, ? hard). Products shall be sampled and prepared, then tested accordingly to examine their conformance to dimensional (mass, thickness, width, and straightness), mechanical (tensile and yield strengths, and elongation), chemical composition, and grain size requirements.
