(Main)

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

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

IEC 60079-10-1:2008 is concerned with the classification of areas where flammable gas or vapour or mist hazards may arise and may then be used as a basis to support the proper selection and installation of equipment for use in a hazardous area. 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 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 hazard may arise due to the presence of combustible dusts or fibres;
d) catastrophic failures which are beyond the concept of abnormality;
e) rommos used for medial purposes;
f) domestic premises.
This first edition of IEC 60079-10-1 cancels and replaces the fourth edition of IEC 60079-10, published in 2002, and constitutes a technical revision. The significant technical changes with respect to the previous edition are:
- introduction of Annex D which deals with explosion hazard from flammable mists generated by the release under pressure of high flash point liquids;
- introduction of Clause A.3 (release rate) which gives thermodynamic equations for release rate with a number of examples for estimating release rate of fluids and gases.

Atmosphères explosives - Partie 10-1: Classement des emplacements - Atmosphères explosives gazeuses

La CEI 60079-10-1:2008 est relative au classement des emplacements dans lesquels des risques dus à des gaz, vapeurs ou brouillards inflammables peuvent apparaître, et ainsi constituer une base pour le choix et l'installation corrects du matériel utilisé dans de tels emplacements. Elle est destinée à être appliquée là où il peut exister un danger d'inflammation du fait de la présence de gaz ou vapeurs inflammables, en mélange avec l'air, dans les conditions atmosphériques normales; mais elle ne s'applique pas:
a) aux mines grisouteuses;
b) au traitement et à la fabrication des explosifs;
c) aux emplacements dans lesquels un danger dû à la présence de poussières ou fibres inflammables peut apparaître;
d) aux défaillances catastrophiques, qui dépassent le concept d'anormalité traité dans la présente norme;
e) aux locaux utilisés à des fins médicales;
f) aux locaux à usage domestique.
Cette première édition de la CEI 60079-10-1 annule et remplace la quatrième édition de la CEI 60079-10, publiée en 2002, et constitue une révision technique. Les principales modifications techniques suivantes ont été apportées par rapport à l'édition précédente:
- introduction de l'Annexe D qui traite du danger d'explosion du brouillard inflammable généré par l'échappement sous pression de liquides au point d'éclair élevé;
- introduction de l'Article A.3 (taux de dégagement) qui donne des équations thermodynamiques pour le taux de dégagement avec des exemples pour l'estimation du taux de dégagement des fluides et de gaz.

IEC 60079-10-1:2020(Main)
Explosive atmospheres - Part 10-1: Classification of areas - Explosive gas atmospheres

IEC 60079-10-1:2020 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 design, construction, operation and maintenance 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 normality dealt with in this standard;
d) rooms used for medical purposes;
e) domestic premises;
f) 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.
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 document 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 document do not apply.
For the purpose of this document, an area is a three-dimensional region or space.
Atmospheric conditions include variations above and below reference levels of 101,3 kPa (1 013 mbar) and 20 °C (293 K), provided that the variations have a negligible effect on the explosion properties of the flammable substances.
In any site, 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 but in some applications other safeguards may also need to be considered. E.g. larger distances may apply for naked flames when considering hot work permits.
This document does not take into account the consequences of ignition of an explosive atmosphere except where a zone is so small that if ignition did occur it would have negligible consequences.
This third edition of IEC 60079-10-1 cancels and replaces the second edition, published in 2015, and constitutes a technical revision, see foreword for further details.

Explosive atmospheres - Part 10-2: Classification of areas - Explosive dust atmospheres

IEC 60079-10-2:2015 is available as IEC 60079-10-2:2015 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.
IEC 60079-10-2:2015 is concerned with the identification and classification of areas where explosive dust atmospheres and combustible dust layers are present, in order to permit the proper assessment of ignition sources in such areas. In this standard, explosive dust atmospheres and combustible dust layers are treated separately. In Clause 4, area classification for explosive dusts clouds is described, with dust layers acting as one of the possible sources of release. In Clause 7 other general considerations for dust layers are described. The examples in this standard are based on a system of effective housekeeping being implemented in the plant to prevent dust layers from accumulating. Where effective housekeeping is not present, the area classification includes the possible formation of explosive dust clouds from dust layers. The principles of this standard can also be followed when combustible fibres or flyings might cause a hazard. This standard is intended to be applied where there can be a risk due to the presence of explosive dust atmospheres or combustible dust layers under normal atmospheric conditions. Please refer to the foreword of the document for a detailed listing of the significant technical changes from the previous edition.

Explosive atmospheres - Part 14: Electrical installations design, selection and erection

IEC 60079-14:2013 contains the specific requirements for the design, selection, erection and initial inspection of electrical installations in, or associated with, explosive atmospheres. Where the equipment is required to meet other environmental conditions, for example, protection against ingress of water and resistance to corrosion, additional protection requirements may be necessary. The requirements of this standard apply only to the use of equipment under standard atmospheric conditions as defined in IEC 60079-0. For other conditions, additional precautions may be necessary, and the equipment should be certified for these other conditions. For example, most flammable materials and many materials which are normally regarded as non-flammable might burn vigorously under conditions of oxygen enrichment. These requirements are in addition to the requirements for installations in non-hazardous areas. This standard applies to all electrical equipment including fixed, portable, transportable and personal, and installations, permanent or temporary. No account is taken in this Standard of the toxic risks that are associated with flammable gases, liquids and dusts in concentrations that are usually very much less than the lower explosive limit. In locations where personnel may be exposed to potentially toxic concentrations of flammable material, appropriate precautions should be taken. Such precautions are outside the scope of this Standard. This fifth edition cancels and replaces the fourth edition published in 2007. This edition constitutes a technical revision. Refer to the document's Foreward for a listing of the specific revisions and additional Notes. Key words: requirements for the design, selection, erection and initial inspection of electrical installations in explosive atmospheres.
The contents of the corrigendum of January 2016, the interpretation sheet 1 of February 2017 and March 2020 have been included in this copy.
