(Specification)Specification for Pre-Patinated Copper for Architectural Applications
Specification for Pre-Patinated Copper for Architectural Applications
ABSTRACT
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.
SCOPE
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
A companion specification for copper sheet and strip for building construction is Specification B 370.
The following precautionary statement pertains only to the test method portion, Section , of this specification: This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
