Kusiyana Pakati pa Kuphulika-Umboni wa Level CT4 ndi BT4

Kuphulika-Umboni Classification

Condition Category	Gasi Gulu	Woimira mpweya	Minimum Ignition Spark Energy
Pansi pa Mgodi	Ine	Methane	0.280mJ
Mafakitole Kunja Kwa Mgodi	IIA	Propane	0.180mJ
	IIB	Ethylene	0.060mJ
	IIC	haidrojeni	0.019mJ

Kalasi I: Zida zamagetsi zosankhidwa kuti zigwiritsidwe ntchito m'migodi ya malasha yapansi panthaka;

Kalasi II: Zida zamagetsi zomwe zimagwiritsidwa ntchito popanga mpweya wophulika, kusiya migodi ya malasha ndi zoikamo zapansi panthaka;

Kalasi II idagawidwa kukhala IIA, IIB, ndi IIC. Zipangizo zolembedwa kuti IIB ndizoyenera malo omwe zida za IIA zimagwiritsidwa ntchito; Zida za IIC zitha kugwiritsidwa ntchito m'malo oyenera zida za IIA ndi IIB.

Kusiyana pakati pa ExdIICT4 ndi ExdIIBT4

Amapereka magulu osiyanasiyana a mpweya.

Ethylene ndi gasi wamba wokhudzana ndi BT4.

haidrojeni ndi acetylene ndi mpweya wamba wa CT4.

Zogulitsa zomwe zidavotera CT4 zimaposa zomwe zidavotera BT4 pamatchulidwe, monga zida za CT4 zitha kugwiritsidwa ntchito m'malo oyenera BT4, pomwe zida za BT4 sizikugwira ntchito m'malo oyenera CT4.
