ABS B thiab ABS E yog cov txheej txheem nkoj tsim cov hlau daim hlau uas tau lees paub los ntawm American Bureau of Shipping (ABS). Lawv sawv cev rau qib sib txawv ntawm qhov kev sib tw toughness xav tau rau ntau qhov chaw pabcuam. Qhov sib txawv tseem ceeb nyob hauv qhov ntsuas qhov ntsuas qhov tsawg kawg nkaus rau lawv cov Charpy V-notch cuam tshuam toughness thiab lawv cov txiaj ntsig ntawm daim ntawv thov.
Qhov txawv tseem ceeb
Qhov sib txawv tseem ceeb yog qhov ntsuas qhov ntsuas kub thiab kev siv cov qauv. ABS Qib B yog ib qho dav dav - lub hom phiaj hlau tsis muaj qhov tshwj xeeb cuam tshuam qhov yuav tsum tau ua. Nws yog siv rau cov khoom tsis yog -cov khoom tseem ceeb hauv kev pabcuam kub ib puag ncig, feem ntau hauv cov hulls sab hauv lossis cov txheej txheem thib ob uas qhov kev pheej hmoo ntawm kev tawg yog tsawg. Hauv qhov tsis sib xws, ABS Qib E yog qib siab -tuaj yeem tsim los rau ib puag ncig hnyav. Nws yog qhov yuav tsum tau ua kom tau raws li qhov muaj zog tiv thaiv lub zog nqus ntawm -40℃F (-40 degree), kom ntseeg tau tias muaj kev ntseeg siab rau cov pob txha tawg hauv Arctic. Yog li ntawd, Qib E tau raug tso cai rau cov tswv cuab tseem ceeb hauv cov nkoj dej khov, cov qauv hauv qab ntug hiav txwv, thiab thaj chaw muaj kev ntxhov siab tshaj plaws ntawm cov nkoj ua haujlwm hauv dej txias heev. Kev xaiv yog tsav los ntawm kev khiav hauj lwm kub thiab kev ua haujlwm tseem ceeb: Qib B yog rau kev siv dav dav, tsis tseem ceeb; Qib E yog qhov tseem ceeb rau cov khoom tseem ceeb hauv kev pabcuam Arctic.
