IEC 60079-10 Electrical apparatus for explosive gas atmospheres - Classification of hazardous areas

Языки: английский, французскийThis part of IEC 60079 is concerned with the classification of hazardous areas where flammable gas or vapour risks may arise, in order to permit the proper selection and installation of apparatus for use in such hazardous areas. It is intended to be applied where there may be a risk of ignition due to the presence of flammable gas or vapour, mixed with air under normal atmospheric conditions (see note 2), but it does not apply to
a) mines susceptible to firedamp;
b) the processing and manufacture of explosives;
c) areas where a risk may arise due to the presence of ignitable dusts or fibres;
d) catastrophic failures which are beyond the concept of abnormality dealt with in this standard (see note 3);
e) rooms used for medical purposes;
f) areas where the presence of flammable mist may give rise to an unpredictable risk and which require special consideration (see note 5);
g) domestic premises.
This standard does not take into account the effects of consequential damage.
