This specification establishes the requirements for sheets and strips of various thicknesses produced from copper (Copper UNS No. C1000), copper-iron alloy (Copper Alloy UNS No. C19400), copper-zinc alloy that is commercial bronze (Copper Alloy UNS No. C22000), copper-zinc alloy that is red brass (Copper Alloy UNS No. C23000), copper-zinc-iron-cobalt alloy (Copper Alloy UNS No. C66400), copper-zinc-iron alloy (Copper Alloy UNS No. C66410), copper-zinc-iron-tin alloy (Copper Alloy UNS No. C66430), cupro-20% nickel (Copper Alloy UNS No. C71000), copper-clad bronze, copper-clad stainless steel, and copper-clad alloy steel. These materials are intended for use as electrostatic or electromagnetic shielding for insulated power, control, instrumentation, and communication cables. Cladding metals may be bonded to the specified base metal by any method that will produce products that will conform to the properties and characteristics prescribed herein. Materials shall be furnished specific to individual metals in the following tempers: H00 (cold-rolled, 1/8 hard), H01 (cold-rolled, ¼ hard), H02 (cold-rolled, ½ hard); O61 (annealed), O81 (annealed, ¼ hard), O50 (light annealed), O61 (annealed, soft), OS035, and OS015. Specimens shall be sampled and prepared, then tested accordingly to examine their conformance to dimensional (mass, thickness, width, straightness, and cladding ratio), mechanical (tensile strength, and Rockwell hardness), electrical (mass resistivity, and conductivity), chemical composition, and grain size requirements.1.1 This specification establishes the requirements for copper, copper alloy, copper-clad bronze (CCB), copper-clad stainless steel (CCS), and copper-clad alloy steel (CAS) materials, sheet, and strip, in various thicknesses, for use as electrostatic or electromagnetic shielding for insulated power, control, instrumentation, and communication cables.NOTE 1: See Specification B736, for related standards for aluminum-based shielding materials.1.2 The products covered are the following:Copper or Copper Alloy UNS No. Type of Products C11000   copperC19400   copper-iron alloyC22000   copper-zinc alloy (commercial bronze)C23000   copper-zinc alloy (red brass)C66400   copper-zinc-iron-cobalt alloyC66410   copper-zinc-iron alloyC66430   copper-zinc-iron-tin alloyC71000   cupro-nickel 20 %...   copper-clad bronze (CCB)...   copper-clad stainless steel (CCS)...   copper-clad alloy steel (CAS)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.1.3.1 The only exception is grain size, which is reported in SI (mm) units.1.4 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.
