(Specification)Standard Specification for Aluminum, Aluminum Alloy and Aluminum-Clad Steel Cable Shielding Stock (Withdrawn 2015)
Standard Specification for Aluminum, Aluminum Alloy and Aluminum-Clad Steel Cable Shielding Stock (Withdrawn 2015)
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.

Cladding ratio must be specified (see 5.4).
1.3 For acceptance criteria for inclusion of new aluminum and aluminum alloys in this specification, see Annex A2.
1.4 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.
The following precautionary caveat pertains only to the test method portion, Section 12, 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 and health practices and determine the applicability of regulatory limitations prior to use.
WITHDRAWN RATIONALE
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).
Formerly under the jurisdiction of Committee B07 on Light Metals and Alloys, this specification was withdrawn in January 2015 in accordance with section 10.5.3.1 of the Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by the end of the eighth year since the last approval date.
