1.1 This specification covers the establishment of the requirements for pre-patinated (artificially aged) copper sheet and strip in ounce-weight thicknesses supplied in flat lengths for roofing, flashing, and other architectural applications.
1.2 The pre-patinated surface is the result of chemical reaction with the copper and shall be applied on one side of the product.
1.2.1 The pre-patinated surface formed is comparable in color and ability to be bent or formed to the surface formed in naturally occurring patinated copper.
1.3 The pre-patinated surface is not the result of coating applications such as painting.
1.4 Materials made to this specification are not intended to be used for electrical applications.
1.5 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.Note 1
