ASTM D866-99

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

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 The values stated in inch-pound units are the standard except in cases where SI units are more appropriate. The values in parentheses are for information only.
