Description

BS PD IEC/TS 60079-39:2015 specifies the construction, testing, installation and maintenanceof Power-i apparatus and systems which utilise electronically controlled spark durationlimitation to maintain an adequate level of intrinsic safety.

This Technical Specification contains requirements for intrinsically safe apparatus and wiringintended for use in explosive atmospheres and for associated apparatus intended forconnection to intrinsically safe circuits entering such atmospheres.

This Technical Specification excludes the level of protection “ia” and the use of softwarecontrolledcircuits.

This Technical Specification applies to electrical equipment utilising voltages not higher than40 V d.c. and a safety factor 1,5 for Groups IIB, IIA, I and III. It is also applicable to Group IIC”ic” apparatus with a safety factor 1,0. Group IIC “ib” apparatus with a safety factor 1,5 arerestricted to voltages up to 32 V d.c.

This type of protection is applicable to electrical equipment in which the electrical circuitsthemselves are incapable of causing an explosion of the surrounding explosive atmospheres.

This Technical Specification is applicable to intrinsically safe apparatus and systems whichutilise electronically controlled spark duration limitation with the aim of providing moreelectrical power while maintaining an adequate level of safety.

This Technical Specification is also applicable to electrical equipment or parts of electricalequipment located outside hazardous areas or protected by another type of protection listedin the IEC 60079 series, where the intrinsic safety of the electrical circuits in explosiveatmospheres depends on the design and construction of such electrical equipment or parts ofsuch electrical equipment. The electrical circuits located in the hazardous area are evaluatedfor use in such locations by applying this Technical Specification.

This Technical Specification supplements and modifies the requirements of IEC 60079-0,IEC 60079-11, IEC 60079-14, IEC 60079-17 and IEC 60079-25.
