Standard Specification for Lead-Coated Copper Sheet and Strip for Building Construction

ABSTRACT
This specification covers ounce-weight thick lead-coated copper sheets and strips in flat lengths or in coils. These materials are recommended for use in roofing, flashing, gutters, downspouts and general sheet metalwork in building constructions but not for electrical applications. This standard contains information on acceptable chemical compositions and mechanical properties of the copper sheets or strips and the lead coating deposited by hot dipping.
SCOPE
1.1 This specification establishes the requirements for lead-coated copper sheet and strip in flat lengths (or in coils) in ounce-weight thicknesses for roofing, flashing, gutters, downspouts, and for the general sheet metalwork in building construction. The lead coating is applied by hot dipping.  
1.2 Products produced to this specification are not intended for electrical applications.  
1.3 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: A companion specification for copper sheet and strip for building construction is Specification B370.  
1.4 The following hazard caveat pertains to the test method portion, Section 17, 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.5 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.
