1 Scope
This part of IEC 60079 is intended to enhance the safety of personnel by providing minimum requirements
for electrical ignition systems for spark-ignited reciprocating internal combustion engines, parts of which provide
Equipment Protection Level (EPL) Gc.
This document provides minimum construction and test requirements, in addition to
manufacturer installation and maintenance recommendations, for the safe operation
of ignition systems and components for spark-ignited reciprocating internal combustion engines providing
EPL Gc for equipment Group IIB+H 2 , IIB or IIA. These requirements apply to systems rated for normal operation with secondary voltages less than or equal to 60 kV.
This document applies only to the ignition systems or the individual ignition system components used on reciprocating internal combustion engines that are stationary
when in operation and mobile machinery where the internal combustion engine can be
potential source of ignition. Applications addressed by the scope of this document
include but are not limited to gas compressors, electric power generators, forklift
trucks, and pumps.
This document does not apply to:
Engine ignition systems that utilize a breaker point or magneto type ignition systems as these would not be suitable for use in a hazardous area.
