Eksplozivne atmosfere - 13. del: Zaščita opreme z zaprtimi prostori z nadtlakom "p" (IEC 60079-13:2010)

Ta del IEC 60079 podaja zahteve za načrtovanje, konstrukcijo, vrednotenje in preskušanje ter označevanje zaprtih prostorov, ki so zaščiteni z nadtlakom, v: - prostoru, lociranem v eksplozivni atmosferi ali nevarnem območju z eksplozivno prašno atmosfero, ki ne vključuje notranjega vira vnetljive snovi ; - prostoru, lociranem na nevarnem območju z eksplozivno plinsko atmosfero ali eksplozivno prašno atmosfero, ki vključuje notranji vir vnetljive snovi; - prostoru, lociranem na nenevarnem območju, ki vključuje notranji vir vnetljive snovi. Prostor lahko sestoji iz ene sobe, več sob, lahko je celotna stavba ali soba znotraj stavbe ter vključuje vstopne in izstopne odprtine. Ta del IEC 60079 prav tako vključuje zahteve za povezano opremo, varnostne naprave in nadzor, potrebne, da se zagotovi vzpostavitev in ohranjanje nadtlaka. Ta del IEC 60079 zajema prostore ali stavbe, ki so zgrajene ali montirane na kraju obratovanja, kar je lahko na kopnem ali na vodi, načrtovane za olajševanje vstopa osebju, ter primarno namenjene namestitvi s strani končnega uporabnika in preverjanju na kraju obratovanja. Prostor je lahko lociran v eksplozivni plinski atmosferi ali eksplozivni prašni atmosferi, ki zahtevata ravni varovanja opreme (EPL) Gb, Db, Gc ali Dc. Ta del IEC 60070 ne določa metod, ki se lahko zahtevajo za zagotovitev primerne kakovosti zraka za osebje, ob upoštevanju strupenosti in temperature znotraj prostora. Ta del IEC 60079 dopolnjuje in spreminja splošne zahteve IEC 60079-0, razen kot je nakazano v preglednici 1. Kjer zahteva tega standarda nasprotuje zahtevi IEC 60079-0, ima zahteva tega standarda prednost.
