I-Ex d IIC T3 Gb luphawu olupheleleyo lokukhusela ukuqhuma, intsingiselo yamalungu ayo ngolu hlobo lulandelayo:
Umzekelo:ibonisa ukuba isixhobo sisixhobo sombane esingaqhushumba, sisishunqulelo sesiNgesi esithi "explosion-proof", esisisixhobo sokuthintela uqhushumbo kufuneka sibe nophawu.
d: imele imowudi yobungqina bokudubula, inombolo esemgangathweni GB3836.2. Isixhobo sokuthintela uqhushumbo sibhekisa kumathuba okuvelisa iintlantsi, ii-arcs kunye namaqondo obushushu ayingozi amacandelo ombane kwiqokobhe ngokusebenza kobungqina bokudubula, iqokobhe linokumelana noxinzelelo logqabhuko lodubulo lomxube werhasi eqhumayo yangaphakathi, kunye nokuthintela ugqabhuko-dubulo lwangaphakathi. iqokobhe elijikeleze ukwanda kwemixube eqhumayo.
IIC:
II ithetha ukuba isixhobo sifanelekile kwindawo yerhasi eqhumayo kwimigodi engeyiyo yamalahle engaphantsi komhlaba njengemizi-mveliso, njl. njl.
I-C ithetha ukuba izixhobo zifanelekile kwiigesi ze-IIC kwiindawo zegesi eziqhumayo. Iigesi ze-IIC zineengozi eziphezulu kakhulu zokuqhuma, iigesi ezimeleyo yi-hydrogen kunye ne-acetylene, enezona mfuno zingqongqo kwizixhobo zokukhusela ukuqhuma.
T3: Ubushushu obuphezulu bomphezulu besixhobo akufuneki budlule kwi-200 ℃. Kwiindawo eziqhumayo, ubushushu bomphezulu besixhobo luphawu olubalulekileyo lokhuseleko. Ukuba ubushushu bomphezulu besixhobo buphezulu kakhulu, bunokutshisa umxube werhasi eqhumayo ejikelezileyo kwaye kubangele ugqabhuko-dubulo.
Gb: imele iNqanaba loKhuseleko lweZixhobo. I-“G” imele iGas kwaye ibonisa ukuba isixhobo sikulungele ukusetyenziswa kwiindawo ezinokuthi zingaqhushumba irhasi. Izixhobo ezinomlinganiselo we-Gb zingasetyenziswa kwi-Zone 1 kunye ne-Zone 2 kwiindawo ezinobungozi.
