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
