Ndi Mulingo Uti Wotsimikizira Kuphulika Ndi Wapamwamba, AT2 kapena BT4

Dongosolo la mavoti osaphulika amalembedwa molunjika monga A < B < C.

III	C	Mtengo wa 135 ℃	Db	IP65
III Fumbi pamwamba		T1450 ℃	Mayi	IP65
		T2 300 ℃	Mb
		T3 200 ℃
	A Zouluka zoyaka moto		Ndipo
		T4 135 ℃
			Db
	B Non conductive fumbi	T2 100 ℃	Dc
	C Fumbi la conductive	T685℃

Kwa 't’ mlingo, Imakumbukiridwa ndi gawo lake la manambala: chiwerengero chachikulu, apamwamba ndi otetezeka mlingo.

Choncho, kuphulika kwa BT4 kumaposa AT2.

Ndikofunikira kufotokozera kuti ndi 't’ amatanthauza malo okwanira kutentha Zida zamagetsi. T4, set pa 135 ° C, ikugwira ntchito zophulika mipweya yokhala ndi mfundo zotsekera zoposa 135 ° C.
