He aha ka Mahana o ka Pahū-Hōʻoia Level AT1

Ma ke aupuni o ka palapala hōʻoia uila pahū, ka “T” ʻO ka māhele e koho ana i nā pūʻulu wela, kahi e hōʻike ai ʻo T1 i ka noho ʻana o ka wela o ka ʻili kiʻekiʻe ma lalo o 450°C.

III	C	T 135 ℃	ʻO Db	IP65
III lepo lepo		T1 450 ℃	Ua haʻi aku ʻo Ma	IP65
		T2 300 ℃	Mb
		T3 200 ℃
	A ʻO nā floc lele lele		A
		T4 135 ℃

	B ʻO ka lepo non conductive	T2 100 ℃	ʻO Dc
	C lepo hoʻokele	T6 85 ℃

ka nui, Hoʻokaʻawale ʻia nā mea uila pahū-hōʻoia i nā pūʻulu wela T4, T5, a me T6. Loaʻa nā hoʻohālikelike T3 akā kakaikahi.
