Anotácia

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+H2, 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:
a) 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.
a) Road vehicles.
b) Low voltage parts and electrical installation that are not included in the ignition system, such as various sensors and thermocouples, throttle actuator(s), fuel control valve(s), human machine interface (HMI), respective harness and wiring and all the other items that might belong to the integrated control system besides the ignition system.
This document supplements and modifies the general requirements of IEC 60079-0 and the requirements of ISO/IEC 80079-41. Where a requirement of this document conflicts with IEC 60079 0 or ISO/IEC 80079-41, the requirement of this document takes precedence.
NOTE - See ISO/IEC 80079-41 for the requirements for explosion protection for EPL Gc reciprocating internal combustion engines
