Electrical apparatus for explosive gas atmospheres - Part 10: Classification of hazardous areas Executive summary Requirements for the classification of hazardous areas to permit the proper selection and installation of apparatus for use in such hazardous areas. Abstract This part of EN 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. This European Standard 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, 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; 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; g) domestic premises. History and related standards This European Standard supersedes BS EN 60079-10:1996 which is withdrawn. This standard includes the following cross-references: IEC 60050(426):1990, IEC 60079-4:1975, IEC 60049-4A:1970 and IEC 60079-20:1996.
