Kusiyana Pakati pa Mulingo Wotsimikizira Kuphulika B ndi C

Gulu la C limapereka chitetezo chokhazikika ndi chithandizo chanzeru kwambiri chosaphulika.

Kutentha gulu la zida zamagetsi	Kutentha kwakukulu kovomerezeka padziko lapansi kwa zida zamagetsi (℃)	Kutentha kwa mpweya / nthunzi (℃)	Miyezo yotentha ya chipangizocho
T1	450	＞450	T1~T6
T2	300	＞300	T2~T6
T3	200	＞200	T3~T6
T4	135	＞135	T4~T6
T5	100	＞100	T5~T6
T6	85	＞85	T6

Mapangidwe a flameproof nthawi zambiri amakhala ndi ulusi m'malo mwa zida zoyikapo. Zida za Gulu C zimapereka malo otalikirapo osayaka moto komanso mipata yocheperako yophulika. haidrojeni, acetylene, ndi carbon disulfide imafuna kugwiritsa ntchito kalasi ya IIC, whereas other substances are adequately served by IIB class.
