Explosive atmospheres - Part 13: Equipment protection by pressurized room "p" and artificially ventilated room "v"
IEC 60079-13:2017(E) gives requirements for the design, construction, assessment, verification and marking of rooms used to protect internal equipment by pressurization or artificial ventilation or both as applicable when located in an explosive gas atmosphere or combustible dust atmosphere hazardous area with or without an internal source of a flammable gas or vapour. It also includes a room located in a non-hazardous area that has an internal source of release of a flammable gas or vapour. This document deals with rooms that are partially constructed in a manufacturer’s facility and intended to have the final installation completed on-site, as well as rooms that are constructed completely on-site. Rooms partially constructed in a manufacturer’s facility may include third-party verification. For rooms built on-site, this document can be used by plant operators as a guide for assessment of those facilities. This document represents a major technical revision of the requirements for equipment protection by pressurized room "p" and artificially ventilated room "v" and should be considered as introducing all new requirements. This second edition cancels and replaces the first edition published in 2010. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - modification of the title of this document to include artificially ventilated room "v" in addition to pressurized room "p"; - addition of types of protection "pb", "pc", and "vc" and removal of types of protection "px", "py", "pz" and "pv"; - definition of the differences between pressurization and artificial ventilation types of protection; - removal of protection of rooms with an inert gas or a flammable gas from the scope of this document; - addition of an informative annex to include examples of applications where types of protection pressurization or artificial ventilation or pressurization and artificial ventilation can be used and associated guidelines. Additional information regarding the scope of this document can be found in Clause 1.
Explosionsgefährdete Bereiche - Teil 13: Schutz von Einrichtungen durch einen überdruckgekapselten Raum "p” und einen fremdbelüfteten Raum "v“
Atmosphères explosives - Partie 13: Protection du matériel par salle à surpression interne "p" et salle ventilée artificiellement "v"
IEC 60079-13:2017 définit les exigences relatives à la conception, la construction, l'évaluation, la vérification et le marquage de salles utilisées pour protéger le matériel interne: – situées dans une atmosphère explosive de Zone 1 ou de Zone 2 ou de Zone 21 ou de Zone 22 n'incluant pas de source interne de dégagement de gaz/vapeur et protégées par surpression interne; – situées dans une atmosphère explosive de Zone 2 incluant ou n’incluant pas de source interne de dégagement de gaz/vapeur et protégées par ventilation artificielle; – situées dans un emplacement non dangereux incluant une source interne de dégagement de gaz/vapeur et protégées par ventilation artificielle; – situées dans une atmosphère explosive de Zone 1 ou de Zone 2 ou de Zone 21 ou de Zone 22 incluant une source interne de dégagement de gaz/vapeur et protégées à la fois par surpression interne et par ventilation artificielle. Le terme «salle» utilisé dans le présent document désigne des salles uniques, plusieurs salles, un bâtiment complet ou une salle contenue dans un bâtiment. Destinée à faciliter l’entrée du personnel, une salle inclut les canalisations d'entrée et de sortie. Une hotte acoustique et d’autres enveloppes similaires destinées à permettre l’entrée du personnel peuvent être considérées comme une salle. Le présent document couvre également les exigences applicables aux dispositifs et contrôles de sécurité nécessaires à l'établissement et au maintien de la ventilation artificielle, du balayage et de la surpression interne. Une salle montée ou construite sur site peut se trouver à terre ou en mer. La salle est principalement destinée à être installée par un utilisateur final, mais elle peut être construite et évaluée à l'usine du fabricant lorsque les opérations de construction finale telles que la réalisation des canalisations peuvent être effectuées sur site. Le présent document ne précise pas les méthodes qui peuvent être exigées pour garantir au personnel une qualité d'air appropriée en matière de toxicité et de température dans la salle. À cet égard, des exigences et règlements nationaux ou autres destinés à garantir la sécurité du personnel peuvent exister. Cette deuxième édition annule et remplace la première édition parue en 2010. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l’édition précédente: a) modification du titre du présent document pour inclure l’expression salle en ventilation artificielle «v» en plus de salle en surpression interne «p»; b) ajout des modes de protection «pb», «pc», et «vc» et suppression des modes de protection «px», «py», «pz» et «pv»; c) définition des différences entre les modes de protection par surpression interne et par ventilation artificielle; d) suppression de la protection des salles par un gaz inerte ou un gaz inflammable relevant du domaine d’application du présent document; e) ajout d’une annexe informative pour inclure des exemples d’applications dans lesquelles les modes de protection par surpression interne et/ou par ventilation artificielle peuvent être utilisés ainsi que des lignes directrices correspondantes.
Eksplozivne atmosfere - 13. del: Zaščita opreme z zaprtimi prostori z nadtlakom "p" in umetno prezračevani prostori (IEC 60079-13:2017)
Ta del standarda IEC 60079 določa zahteve za načrtovanje, gradnjo, ocenjevanje, preverjanje in označevanje prostorov, ki se uporabljajo za zaščito notranje opreme:
– v eksplozivni atmosferi cone 1, 2, 21 ali 22 (območje, ki običajno zahteva stopnjo zaščite opreme (EPL) Gb, Gc, Db ali Dc) brez notranjega vira izpusta plinov/hlapov in z zaščito z nadtlakom;
– v eksplozivni atmosferi cone 2 (območje, ki običajno zahteva stopnjo zaščite opreme Gc) z notranjim virom izpusta plinov/hlapov ali brez njega in z zaščito z umetnim prezračevanjem;
– v nenevarnem območju z notranjim virom izpusta plinov/hlapov in zaščito z umetnim prezračevanjem;
– v eksplozivni atmosferi cone 1, 2, 21 ali 22 (območje, ki običajno zahteva stopnjo zaščite opreme Gb, Gc, Db ali Dc) z notranjim virom izpusta plinov/hlapov ter zaščito z nadtlakom in umetnim prezračevanjem.
Izraz »prostor«, ki se uporablja v tem dokumentu, vključuje posamezne prostore, več prostorov, celotno zgradbo ali prostor znotraj zgradbe. Prostor je namenjen zagotavljanju lažjega vstopa osebja ter vključuje vhodne in izhodne kanale. Kot prostor se lahko obravnavajo akustični okrovi in druga podobna ohišja, namenjena vstopu osebja.
Ta dokument zajema tudi z zahtevami povezane varnostne naprave in kontrolnike, ki so potrebni za vzpostavitev in vzdrževanje umetnega prezračevanja, čiščenja ter ustvarjanje nadtlaka.
Prostor, sestavljen ali izdelan na mestu uporabe, je lahko na kopnem ali na vodi. Prostor je primarno namenjen namestitvi, ki jo izvede končni uporabnik, vendar je lahko izdelan in ocenjen v proizvodnem obratu, končna namestitev pa se opravi na mestu uporabe.
Prostor je lahko v atmosferi eksplozivnega plina, ki zahteva stopnjo zaščite opreme Gb ali Gc, ali v atmosferi gorljivega prahu, ki zahteva stopnjo zaščite opreme Db ali Dc.
Ta dokument ne določa metod, ki bi morda bile potrebne za zagotavljanje ustrezne kakovosti zraka za osebje v zvezi s toksičnostjo in temperaturo v prostoru. Za zagotavljanje tovrstne varnosti osebja obstajajo morda nacionalni ali drugi predpisi in zahteve.
Zaščita prostorov z uporabo inertnega plina ali gorljivega plina ne spada na področje uporabe tega dokumenta. Takšni primeri uporabe se obravnavajo kot posebni primeri, ki se jih deloma lahko obravnava na podlagi načel iz standarda IEC 60079-2, vendar pa bodo najverjetneje tudi predmet dodatnih, strogih tehničnih standardov, postopkov in praks. Ohišja z nadtlakom za opremo, ki ni namenjena zagotavljanju lažjega vstopa osebja, so obravnavana v standardu IEC 60079-2 in ne spadajo na področje uporabe tega dokumenta.
OPOMBA: Priporočila za vzdrževanje so v dodatku A, dokler se ne vključijo v IEC 60079-17.
Ta dokument dopolnjuje in spreminja splošne zahteve standarda IEC 60079-0, razen izključitev, kot je prikazano v preglednici 1. Kadar je zahteva iz tega dokumenta v nasprotju z zahtevo iz standarda IEC 60079-0, ima prednost zahteva iz tega dokumenta.
