Standard Specification for Copper, Copper-Alloy, Copper-Clad Bronze (CCB), Copper-Clad Stainless Steel (CCS), and Copper-Clad Alloy Steel (CAS) Sheet and Strip for Electrical Cable Shielding
ABSTRACT
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.
SCOPE
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.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
