Chithandizo cha kutentha:

Mbale zochindikala mamilimita 40 [1.5 mkati] kapena pansi pake nthawi zambiri zimaperekedwa ngati zopindidwa. Ngati pakufunika normalized kapena nkhawa anamasuka adzadziwitsidwa pamaso kuti.
Mimbale yokulirapo kuposa mamilimita 40 [1.5 mu] iyenera kukhala yokhazikika.
Ngati kuyezetsa kulimba kwa notch kukufunika pa mbale 1.5 mu [mamilimita 40] ndipo pansi pa makulidwe awa, mbalezo ziyenera kukhala zachilendo pokhapokha ngati wogula wafotokozera.
Kuvomerezedwa ndi wogula, mitengo yozizirira mwachangu kuposa kuziziritsa kwa mpweya ndiyololedwa kuwongolera kulimba, malinga ngati mbalezo zimatenthedwa mu 1100 mpaka 1300 ℉ [595 mpaka 705 ℃].

Zolemba Zotsatiridwa:

Miyezo ya ASTM:
A20/A20M: Zofunikira zonse za mbale zachitsulo zotengera zokakamiza ndi akasinja
A435/A435M: Mafotokozedwe a zowunikira zowongoka zazitsulo zazitsulo
A577/A577M: Pakuti ngodya-mtengo akupanga kufufuza mbale zitsulo
A578/A578M: ​​Pakuwunika mowongoka kwa UT kwa mbale zopindidwa zamapulogalamu apadera
