Xa uphatha izinto ezinobungozi okanye usebenza kwiindawo ezinokuqhuma, i-Ex rating yeemoto ezingakwaziyo ukuqhuma yinto ebalulekileyo ekufuneka iqwalaselwe. Ezi moto zenzelwe ngokukodwa ukuthintela ukutsha kwezinto ezinokutsha, ukuqinisekisa ukhuseleko lwezixhobo kunye nabasebenzi ababandakanyekayo.
Enye yezona klasi ziqhelekileyo ze-Ex kwiimoto ezingakwaziyo ukuqhuma yi-Ex dII BT4. Olu vavanyo lubonisa ukuba imoto ifanelekile ukusetyenziswa kwiindawo ezineegesi ezinokuthi ziqhume, ezifana neendawo zokucocisa, izityalo zeekhemikhali okanye amaqonga aselunxwemeni. Uhlu lwe-"dII" luthetha ukuba imoto yakhiwe ngendlela ethintela iigesi ezivuthayo kunye nomphunga ukuba ungangeni kwiindawo zayo zangaphakathi. Igama elithi "BT4" libhekisa kubushushu obuphezulu bomphezulu wemoto obungafanele budlule kwi-135°C kwaye buthathwa njengokhuselekileyo kwindawo enobungozi ejikelezileyo.
Olunye udidi olubalulekileyo lokukhusela ukuqhuma kweemoto ezingakwaziyo ukuqhuma yi-Ex dII CT4. Olu hlu lufana ne-Ex dII BT4, kodwa luyilelwe ngokukodwa iindawo ezinothuli olunokuqhushumba, njengeendawo zokugcina iinkozo, izityalo zamayeza okanye imigodi yamalahle. Igama elithi "CT4" libonisa ubushushu obuphezulu obunokufikelelwa kumphezulu wangaphandle wemoto phantsi kweemeko zokusebenza eziqhelekileyo ngaphandle kokubangela ukuqhuma. Kwiimoto ze-Ex dII CT4, lo mda wobushushu umiselwe kwi-95°C.
Iimoto ezikhusela ukuqhuma ze-Ex dII BT4 kunye ne-Ex dII CT4 zivavanyelwa kakhulu kwaye ziqinisekiswe ukuqinisekisa ukuba ziyahambelana nemigangatho yokhuseleko yamazwe ngamazwe. Ezi moto kufuneka zihlangabezane neemfuno ezingqongqo, kubandakanya ukusetyenziswa kwezinto eziqinileyo nezihlala ixesha elide, iindlela zokwenza ezichanekileyo, iimpawu zokhuseleko eziphuculweyo kunye nokuhlolwa okucokisekileyo. Isiqinisekiso esikhusela ukuqhuma sinika abaqhubi uxolo lwengqondo besazi ukuba iimoto ezisetyenziswa kwiindawo ezinobungozi zenzelwe ngokukodwa ukuthintela imithombo yokutsha kunye nokunciphisa umngcipheko wokuqhuma.
Ngamafutshane, i-Ex rating yeemoto ezingakwaziyo ukuqhuma idlala indima ebalulekileyo ekugcineni ukhuseleko kwiindawo ezinobungozi. Nokuba yi-Ex dII BT4 kwiindawo zegesi okanye yi-Ex dII CT4 kwiindawo zothuli, ezi moto zenzelwe ngononophelo ukuthintela ukutsha nokuqinisekisa ukhuseleko oluphezulu ekuqhumeni. Ngokukhetha iimoto ezinereyithingi efanelekileyo yokukhusela ukuqhuma, amashishini anokunciphisa kakhulu umngcipheko weengozi, akhusele izixhobo ezixabisekileyo, kwaye akhusele ubomi babasebenzi abasebenza kwiindawo ezinokubangela ukuqhuma.
