BV D460 yog qhov siab - Lub zog {1} Lub zog Steel Daim ntawv "D460" yog tus yuam sij rau kev nkag siab nws cov khoom.
BV (Bureau Veritas): Qhov no qhia tias cov hlau yog tsim tawm, xeem, thiab ntawv pov thawj, thiab cov cai nruj raws li cov cai nruj thiab cov qauv ntawm Bureau Veritas. Daim ntawv pov thawj no tseem ceeb heev rau cov ntaub ntawv siv tau siv rau hauv cov qauv marine, kom ntseeg tau thiab muaj kev nyab xeeb kom nyab xeeb.
D: Qhov sawv rau qib, qhia txog qib theem tshwj xeeb nrog cov khoom tau hais tseg cov khoom siv.
460: Tus lej no txhais tau tias tsawg kawg yog los lub zog muaj zog ntawm cov hlau. Nws txhais tau hais tias lub phaj no tau muaj txiaj ntsig lub zog ntawm 460 megapualals (MPA) lossis siab dua. Tos lub zog yog qhov kev ntxhov siab uas ib qho khoom siv pib deform plastically (piv txwv li, nws yuav tsis rov qab mus rau nws cov qauv qub).
