This specification establishes the requirements for rolled copper sheets and strips in flat lengths or coils of ounce-weight thicknesses for roofing, flashing, gutters, downspouts, and general sheet metal work in building construction. Products produced to this specification are not intended for electrical applications. Materials are available in the following tempers: O60 (soft), H00 (cold-rolled), H01 (cold-rolled, high yield), H02 (half hard), H03 (three-quarter hard), and H04 (hard). Products shall be sampled and prepared, then tested accordingly to examine their conformance to dimensional (mass, thickness, length, width, weight, and straightness), mechanical (tensile and yield strength, and Rockwell hardness), chemical composition, and grain recrystallization requirements.

1.1 This specification establishes the requirements for rolled copper sheet and strip in flat lengths or coils in ounce-weight thicknesses for roofing, cladding, flashings, gutters, downspouts, and general sheet metal work for building construction.

1.1.1 Products produced to this specification are not intended for electrical applications.

1.2 Units—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: Specification B101 is an associated specification for lead-coated copper sheets and strip for building construction.

1.3 The following hazard caveat pertains to the test methods portion, Section 16, of this specification

1.3.1 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
