Standard Specification for Fully Cured Silicone Rubber-Coated Glass Fabric and Tapes for Electrical Insulation (Withdrawn 2013)

ABSTRACT
This specification covers fully cured silicone rubber-coated glass fabric in sheet form, full-width rolls, and tapes to be used as electrical insulation. The glass fabric and the silicone rubber shall be of good commercial quality and shall be such as to produce a product that will meet the requirements. The properties of the silicone rubber-coated glass fabric and tapes shall conform to the requirements prescribed.
SCOPE
1.1 This specification covers fully cured silicone rubber-coated glass fabric in sheet form, full-width rolls, and tapes to be used as electrical insulation.
WITHDRAWN RATIONALE
This specification covers fully cured silicone rubber-coated glass fabric in sheet form, full-width rolls, and tapes to be used as electrical insulation.
Formerly under the jurisdiction of Committee D09 on Electrical and Electronic Insulating Materials, this practice was withdrawn in January 2013 in accordance with section 10.5.3.1 of the Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by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.
