Abstract

Specifies requirements for insulating materials which are used for the support and insulating of live parts of cable coupling devices, but excluding cables, intended for use in coal mines. Mechanical, electrical and thermal properties are specified.

Scope

This Standard applies to insulating materials which are used for the support and insulation of live parts of cable coupling devices, but excluding cables, intended for use in coal mines.

The tests specified herein are intended as type tests and are made on prepared specimens as described in the appendices.
