O le fea Lauga ole Pa-Fa'amau e Sili Atu, CT1 poʻo CT4

O le fa'avasegaga fa'amaonia o le pa'u o le CT4 e manatu maualuga.

Mafaufau uma, o masini ta'itasi o lo'o umia se fa'ailoga IIC, fa'aalia le tutusa i lenei metric; peita'i, o lo'o maua i totonu o latou fa'avasegaga o le vevela: O masini T6 o lo'o i ai le maualuga o le vevela o le luga ole 85°C, O masini T4 e maualuga i le 135°C, ma masini T1 e mafai ona oʻo atu i le 450°C.

T4-fa'atauina mea pa'u-fa'amaonia masini e fa'atauaina tele ma e mafai ona suitulaga atoa mo masini fa'atau T1.. O lona uiga, sui CT1 meafaigaluega ma CT4 i soʻo se talosaga faʻamautinoa le saogalemu.
