Explosive atmospheres - Part 10-1: Classification of areas - Explosive gas atmospheres

被代替

IEC 60079-10-1:2015 发布历史

This part of IEC 60079 is concerned with the classification of areas where flammable gas or vapour hazards may arise and may then be used as a basis to support the proper selection and installation of equipment for use in hazardous areas. It is intended to be applied where there may be an ignition hazard due to the presence of flammable gas or vapour, mixed with air, but it does not apply to: a) mines susceptible to firedamp; b) the processing and manufacture of explosives; c) catastrophic failures or rare malfunctions which are beyond the concept of abnormality dealt with in this standard (see 3.7.3 and 3.7.4); d) rooms used for medical purposes; e) commercial and industrial applications where only low pressure fuel gas is used for appliances e. g. for cooking, water heating and similar uses, where the installation is compliant with relevant gas codes; f) domestic premises; g) where a hazard may arise due to the presence of combustible dusts or combustible flyings but the principles may be used in assessment of a hybrid mixture (refer also IEC 60079-10-2). NOTE Additional guidance on hybrid mixtures is provided in Annex I. Flammable mists may form or be present at the same time as flammable vapour. In such case the strict application of the details in this standard may not be appropriate. Flammable mists may also form when liquids not considered to be a hazard due to the high flash point are released under pressure. In these cases the classifications and details given in this standard do not apply. Information on flammable mists is provided in Annex G. For the purpose of this standard, an area is a three-dimensional region or space. Atmospheric conditions include variations above and below reference levels of 101,3 kPa (1013 mbar) and 20 °C (293 K), provided that the variations have a negligible effect on the explosion properties of the flammable substances. In any process plant, irrespective of size, there may be numerous sources of ignition apart from those associated with equipment. Appropriate precautions will be necessary to ensure safety in this context. This standard is applicable with judgement for other ignition sources. This standard does not take into account the consequences of ignition of an explosive atmosphere.
