ASTM D866-99(2004)

Standard Specification for Crosslinked Styrene-Butadiene (SBR) Synthetic Rubber Jacket for Wire and Cable (Withdrawn 2009)

ABSTRACT
This specification covers a crosslinked styrenebutadiene (SBR) synthetic rubber compound suitable for use as the outer covering or jacket on insulated electrical wires or cables for heavy-duty service. Physical properties of the synthetic rubber before aging, after aging, and after air oven testing such as tensile strength, tension, and elongation at rupture shall be determined.
SCOPE
1.1 This specification covers a crosslinked styrene-butadiene (SBR) synthetic rubber compound suitable for use as the outer covering or jacket on insulated electrical wires or cables for heavy-duty service.
1.2 This jacket is not recommended for installation at a temperature lower than 35 °C.
1.3 Whenever two sets of values are presented, in different units, the values in the first set are the standard, while those in parentheses are for information only.
WITHDRAWN RATIONALE
This specification covers a crosslinked styrene-butadiene (SBR) synthetic rubber compound suitable for use as the outer covering or jacket on insulated electrical wires or cables for heavy-duty service.
Formerly under the jurisdiction of Committee D09 on Electrical and Electronic Insulating Materials, this specification was withdrawn without replacement in 2010 because there is no indication that this specification is being used in the industry.
