Equipment protection by pressurized room “p” and 6007-2 ventilated room “v” IEC The numerous changes are identified in the Foreward of the document.
The significant changes with respect to the previous edition are listed below: Equipment repair, overhaul and reclamation” “IEC However, data on air-inert mixtures are not tabulated. Equipment protection by powder filling “q” IEC The principles of this standard can also be followed when combustible fibres or flyings might cause a hazard.
Caplights for use in een susceptible to firedamp – General requirements – Construction and testing in relation to the risk of explosion “IEC This standard is intended to be applied where 600079-2 can be a risk due to the presence of explosive dust atmospheres or combustible dust layers under normal atmospher ic conditions.
While it does not preclude the use of other quality management systems that are compatible with the objectives of ISO The significant technical changes with respect to the previous edition are: The enclosure must be able to withstand 1.
It may also be applied to caplights for use in mines dn likely to be endangered by firedamp. The materials and the characteristics included in a table see Annex B have been selected with particular reference to the use of equipment in hazardous areas.
This standard supplements IECthe requirements of which apply to electrical apparatus used in intrinsically safe electrical ne.
