Specifies the application, materials, construction, dimensions and tests for elastomer insulated and sheathed reeling and trailing electric cables, for use in underground coal mines.

This Standard specifies elastomer-insulated, elastomer-sheathed reeling and trailing electric cables for use in underground coal mines. An essential feature of this Standard is the requirement that cables used for alternating current supply be electrically symmetrical.This Standard is intended to apply only to cables of the types provided for in the tables of construction and dimensions. It is not intended, however, that the use of other types or sizes of cables should be precluded, and regulatory authorities may give approval to new types as they are developed. Appropriate requirements for new types and sizes will eventually be included in this Standard as the need arises.This Standard also provides the basis of requirements for other sizes in the range of materials covered here.
