Internal combustion engines

Scope

This International Standard covers the technical requirements necessary to avoid or minimize the
significant hazards listed in Clause 4, which could occur during normal operation, maintenance or
foreseeable malfunction of internal combustion engines including
• Group I EPL Mb for use in underground workings susceptible to firedamp and/or combustible
dust,
• Group II EPL Gb and Gc for use in potentially explosive atmospheres of flammable gas and
vapour and
• Group III EPL Db and Dc for use in potentially explosive atmospheres of combustible dust.
This International Standard includes those tests of the engine and its ancillary devices that are
required to verify compliance.
This International Standard applies to reciprocating internal combustion engines with compression
ignition and spark ignition.

This International Standard does not define requirements relating to the driven machinery and
equipment.
This International standard does not apply to flammable gas and vapour atmospheres containing
carbon disulphide (CS2) and/or ethylenoxide (C2H4O) due to special properties of these gases.
This International standard does not apply to engines used in areas for the processing
manufacture or storage of explosives.
The International Standard solely deals with explosion protection requirements. Requirements on
emissions are not covered by this standard.
General safety requirements are not included in this International Standard.
NOTE General safety requirements i.e. those common to internal combustion engines, are covered for the EU in
EN 1679-1.
