Establishes requirements for flameproof equipment attached to, or forming part of, a diesel engine for use in coal, and other, mines susceptible to firedamp. Covers definitions, joints within the flameproof enclosure, air inlet system, exhaust and conditioning system, flame traps, fuel systems, engine shut-down, condition monitoring, electrical apparatus, verification testing, maintenance literature and marking.

This British Standard specifies requirements for flameproof equipment attached to, or forming part of, a diesel engine for use in coal, and other, mines susceptible to firedamp. The use of diesel engines in such mines imposes environmental constraints on the equipment and these constraints are detailed in the standard.

The tests which the diesel engine and its ancillary fittings are required to undergo to prove compliance with this standard are detailed in the appendices.

NOTE. The titles of the publications referred to in this standard are listed on the inside back cover.
