1.1 This specification covers durable, crosslinked black or colored acrylonitrile-butadiene/poly(vinyl chloride) (NBR/PVC) compounds suitable for use as outer coverings or jackets on electrical cables for general-purpose, heavy-duty, and extra-heavy-duty service.

1.2 General-purpose and heavy-duty jackets are not recommended for installation at a temperature lower than 25°C and extra-heavy-duty jackets at a temperature lower than 10°C.

1.3 Compounds are based on a fluxed blend of an acrylonitrile-butadiene synthetic rubber and poly(vinyl chloride) resin.

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