This part of IEC applies to electrical equipment where the rated input voltage does not 06079-2 15 kV r. It provides recommendations for the design, installation, maintenance and repair of trace heating systems including associated control and monitoring equipment. The electrical circuits exposed to the explosive atmosphere are evaluated for use in such an atmosphere by applying this standard.

BS EN Explosive atmospheres. Equipment protection by pressurized enclosure “p”
The supply of purging and pressurising air is managed by a special control unit. This standard should be read in conjunction with ISO This standard does not apply to dusts of explosives, which do not require atmospheric oxygen for combustion, or to pyrophoric substances. This method of protection has the benefits of Flameproof but does not require a specialised enclosure, generally a standard Industrial enclosure is suitable. Ex “ia”, Ex “ma”, Ex “da” cannot be applied.
This second edition cancels and replaces the first edition, published inand constitutes a full technical revision.
