Phapang Pakeng tsa Maemo a Bopaki ba Ho phatloha IIC le IIIC

Tsena li emela likhopolo tse fapaneng ka ho feletseng.

Boemo ba Sehlopha	Karolelano ea Khase	Likhase tse emetseng	Minimum Ignition Spark Energy
Tlas'a Morafo	I	Methane	0.280mJ

IIC hangata e amahanngoa le libaka tse thibelang ho phatloha, e tšoauoa ka lintho tse kang hydrogen le ethyl nitrate. Ka lehlakoreng le leng, IIIC, joalo ka ha ho hlalosoa ke maemo a naha, e mabapi le ho phatloha ha lerole ho tsamaisang, e khethiloeng e le DIP A21. IIIA e akaretsa e ka chang likhoele, le IIIB e akaretsa lerōle le se nang conductive.

IIC ha e fetohe le IIIC; ka hona, lihlahisoa tse nang le litekanyetso tse thibelang ho phatloha ha lerole joalo ka DIP A20/A21 li lokela ho khethoa.
