A242 hom 1 yog hom huab cua -} tiv taus cov hlau txheem. Nws yog qhov siab - lub zog, qis {{}}}} huab cua all} ineloces} allloconed los ntawm American Society rau kev sim thiab cov ntaub ntawv (ASTM). Hom hlau no tau tsim los muab kev tiv thaiv zoo thaum nthuav tawm cov huab cua nyob rau saum npoo, txo qhov kev pheej hmoo ntawm corrosion ntawm cov hlau hauv.
A242 Hom 1 Hlau yog cim los ntawm cov huab cua zoo heev: los ntawm kev tsim ua zoo, thaum muaj kev sib dhos thiab cov txheej txheem nplaum thiab cov nplaum thiab cov khoom sib txuas. Qhov pua xeb no tau zoo thaiv kev yaig los ntawm oxygen thiab noo noo. Cov Hlau Hlau Hlau. Lub Zog Siab: A242 Hom 1 Hlau muaj qhov siab ntau thiab haum rau kev siv hauv cov txheej txheem sib xyaw uas yuav tsum tau tiv thaiv loj dua. Cov nqi kho tus nqi qis dua: vim nws corrosion tsis kam, nquag ovi- corrosion txheej txij nkawm yog tsis xav tau thaum muaj ntev thaum siv.
