Abstract
This specification covers selected uncoated or coated aluminum, aluminum alloy, and aluminum clad steel cable shielding stocks used for electrostatic or electromagnetic shielding in insulated power, control, instrumentation, and communication cables including coaxial cables. Claddings may be bonded to the base metal by any method, provided it can produce a clad material that conforms to the requirements. Aluminum materials should be furnished in Temper 0 while aluminum clad steel materials should be in the annealed temper. When specified, cable shielding stock may be coated with a protective plastic coating on one or both sides.
Scope
1.1 This specification covers selected aluminum, aluminum-alloy and aluminum clad steel cable shielding stock, both uncoated and coated, for applications such as electrostatic or electromagnetic shielding for insulated power, control, instrumentation and communication cables (including coaxial cable). Note 1See B 694, Specification for Copper, Copper Alloy, and Copper-Clad Stainless Steel Sheet and Strip for Electrical Cable Shielding for related standards for copper-based shielding materials.
1.2 The materials covered are the following:
Aluminum 1060 Aluminum designations are in accordance with ANSI H35.1. The equivalent Unified Numbering System alloy designations are those shown preceded by A9, for example, A91100 for Aluminum 1100 in accordance with Practice E 527.
Cladding ratio must be specified (see 5.4).
