Anotace

This specification establishes of the requirements for pre-patinated (artificially aged) copper sheets and strips in ounce-weight thicknesses supplied in flat lengths for roofing, flashing, and other architectural applications. Materials made to this specification are not intended to be used for electrical applications. The pre-patinated surface shall not be the result of coating applications such as painting, but rather the result of chemical treatment that artificially ages the base metal to form green- to turquoise-colored protective layer. Products shall be produced in tempers H00 (eighth hard, cold-rolled), H01 (quarter hard, cold-rolled high yield), and H02 (half hard). Products shall be tested to examine their conformance to dimensional (mass, thickness, weight, width, length, and straightness), mechanical (tensile and yield strengths, and Rockwell hardness), and chemical composition requirements. Products shall also undergo color fade resistance and resistance to flaking tests.
