(Main)Explosive atmospheres - Part 0: Equipment - General requirements
Explosive atmospheres - Part 0: Equipment - General requirements
This part of IEC 60079 specifies the general requirements for construction, testing and
marking of Ex Equipment and Ex Components intended for use in explosive atmospheres.
The standard atmospheric conditions (relating to the explosion characteristics of the
atmosphere) under which it may be assumed that Ex Equipment can be operated are:
• temperature –20 °C to +60 °C;
• pressure 80 kPa (0,8 bar) to 110 kPa (1,1 bar); and
• air with normal oxygen content, typically 21 % v/v.
This part of IEC 60079 and other standards supplementing this standard specify additional
test requirements for Ex Equipment operating outside the standard temperature range, but
further additional consideration and additional testing may be required for Ex Equipment
operating outside the standard atmospheric pressure range and standard oxygen content.
Such additional testing may be particularly relevant with respect to Types of Protection that
depend on quenching of a flame such as ‘flameproof enclosures “d”’ (IEC 60079-1) or
limitation of energy, ‘intrinsic safety “i”’ (IEC 60079-11).
NOTE 1 Although the standard atmospheric conditions above give a temperature range for the atmosphere
of -20 °C to +60 °C, the normal ambient temperature range for the Ex Equipment is –20 °C to +40 °C, unless
otherwise specified and marked. See 5.1.1. It is considered that –20 °C to +40 °C is appropriate for many items of
Ex Equipment and that to manufacture all Ex Equipment to be suitable for a standard atmosphere upper ambient
temperature of +60 °C would place unnecessary design constraints.
NOTE 2 Requirements given in this standard result from an ignition hazard assessment made on equipment. The
ignition sources taken into account are those found associated with this type of equipment, such as hot surfaces,
electromagnetic radiation, mechanically generated sparks, mechanical impacts resulting in thermite reactions,
electrical arcing and static electric discharge in normal industrial environments.
NOTE 3 Where an explosive gas atmosphere and a combustible dust atmosphere are, or can be, present at the
same time, the simultaneous presence of both often warrants additional protective measures. Additional guidance
on the use of Ex Equipment in hybrid mixtures (mixture of a flammable gas or vapour with a combustible dust or
combustible flyings) is given in IEC 60079-14.
IEC 60079 does not specify requirements for safety, other than those directly related to the
explosion risk.
Ignition sources like adiabatic compression, shock waves, exothermic chemical reaction, selfignition
of dust, naked flames and hot gases/liquids, are not addressed by this standard.
NOTE 4 Although outside the scope of this standard, such equipment would typically be subjected to a hazard
analysis that identifies and lists all of the potential sources of ignition by the equipment and the measures to be
applied to prevent them becoming effective. See ISO/IEC 80079-36.

NEW!IEC 60079-0:2017 est disponible sous forme de IEC 60079-0:2017 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'édition précédente.
IEC 60079-0:2017 spécifie les exigences générales de construction, d'essais et de marquage de l’appareil Ex et des Composants Ex destinés à être utilisés dans des atmosphères explosives. Les conditions atmosphériques normales (relatives aux caractéristiques d’explosion de l’atmosphère) dans lesquelles, par hypothèse l’appareil Ex peut être utilisé, sont les suivantes:
-température de –20 °C à +60 °C;
-pression de 80 kPa (0,8 bar) à 110 kPa (1,1 bar); et
-air avec teneur normale en oxygène, typiquement 21 % v/v.
La présente partie de la norme IEC 60079 et les autres normes qui la complètent spécifient des exigences d’essai supplémentaires pour les appareils Ex fonctionnant hors de la plage normale de températures, une attention supplémentaire ultérieure et des essais complémentaires pouvant toutefois être exigés pour les appareils Ex fonctionnant hors de la plage normale de pressions atmosphériques et de la teneur normale en oxygène. De tels essais complémentaires peuvent se révéler pertinents, notamment pour les modes de protection qui dépendent de l’extinction d’une flamme, tels qu’une «enveloppe antidéflagrante «d»» (IEC 60079-1), ou de la limitation de l’énergie, tels que la «sécurité intrinsèque «i»» (IEC 60079-11). Reportez-vous à l'avant-propos du document pour une liste complète des modifications techniques entre l'édition 7.0 et édition précédente du document.
Mots-clés: l’appareil Ex et des Composants Ex destinés à être utilisés dans des atmosphères explosives.
Eksplozivne atmosfere - 0. del: Oprema - Splošne zahteve
Ta del standarda IEC 60079 določa splošne zahteve za konstrukcijo, preskušanje ter označevanje opreme in komponent Ex, ki so namenjene uporabi v eksplozivnih atmosferah. Standardni atmosferski pogoji (povezani z eksplozijskimi značilnostmi atmosfere), na podlagi katerih se lahko sklepa, da je opremo Ex mogoče uporabljati, so:
• temperatura od –20 °C do 60 °C;
• tlak od 80 kPa (0,8 bara) do 110 kPa (1,1 bara); in
• zrak z normalno vsebnostjo kisika, običajno z 21-odstotnim masnim deležem.
Ta del standarda IEC 60079 in drugi standardi, ki dopolnjujejo ta standard, določajo dodatne preskusne zahteve za opremo Ex, ki deluje zunaj običajnega temperaturnega razpona, vendar sta za opremo Ex, ki deluje zunaj običajnega razpona atmosferskega tlaka in običajne vsebnosti kisika, morda potrebna dodatna obravnava in preskušanje.
Takšno dodatno preskušanje je lahko pomembno zlasti v povezavi z vrstami zaščite, ki so odvisne od gašenja plamena, npr. »ognjevarno ohišje ’d’« (IEC 60079-1), ali omejitve energije, npr. »lastnovarne električne naprave ’i’« (IEC 60079-11).
OPOMBA 1: Čeprav je za zgornje običajne atmosferske pogoje podan temperaturni razpon atmosfere od –20 °C do 60 °C, je običajen razpon sobne temperature opreme Ex od –20 °C do 40 °C, razen če ni določeno ali označeno drugače. Glej točko 5.1.1. Upošteva se, da je razpon od –20 °C do 40 °C primeren za številne elemente opreme Ex in da bi pri proizvodnji opreme Ex, ki bi ustrezala običajni atmosferi, zgornja mejna vrednost sobne temperature 60 °C povzročila nepotrebne oblikovne omejitve.
OPOMBA 2: Zahteve, podane v tem standardu, izhajajo iz ocene nevarnosti vžiga, ki je bila izvedena za opremo. Upoštevani viri vžiga, npr. vroče površine, elektromagnetno sevanje, mehansko povzročene iskre, mehanski udarci, ki povzročijo reakcijo termita, električni oblok in elektrostatični naboj v običajnih industrijskih okoljih, so povezani s to vrsto opreme.
OPOMBA 3: Če sta hkrati (lahko) prisotni atmosfera eksplozivnega plina in atmosfera gorljivega prahu, je običajno treba sprejeti dodatne zaščitne ukrepe. Dodatna navodila o uporabi opreme Ex v hibridnih mešanicah (mešanica vnetljivega plina ali hlapa in gorljivega prahu ali odpadkov iz predilnic) so podana v standardu IEC 60079-14.
Standard IEC 60079 ne določa zahtev za varnost, razen tistih, ki so neposredno povezane
z nevarnostjo eksplozije.
Viri vžiga, kot so adiabatska kompresija, tlačni skoki, eksotermna kemična reakcija, samovžig prahu,
odprti plamen in vroči plini/tekočine, niso obravnavani v tem standardu.
OPOMBA 4: Čeprav takšna oprema ne spada na področje uporabe tega standarda, se zanjo običajno izvede analiza nevarnosti, na podlagi katere se določi in navede vse morebitne vire vžiga opreme ter ukrepe, s katerimi je mogoče preprečiti vžig. Glej standard ISO/IEC 80079-36.
