Iso 6892-2}}: Tensile kev kuaj xyuas ntawm cov khoom siv ntawm cov khoom kub ntawm cov chaw kub
Iso 6892-2 yog ib qho kev ntsuas ntsuas feem ntau rau cov ntaub ntawv ntsuas tensile ntawm cov khoom kub (ntau dua 35 35). Iso 6892-2: 2018 yog cov kev hloov pauv tam sim no ntawm cov hlau ntsuas. Nws tau luam tawm thawj zaug xyoo 2011, thaum nws tso tseg thiab hloov cov txheej txheem yav dhau los uas tswj hwm kev sim ntsuas kub - ISO 783: 1999.
Kev ntsuas kub kub yog feem ntau siv nyob rau hauv kev lag luam AERPACACE, qhov chaw uas yog xim hlau cov tshuab thiab cov qauv yuav tsum muaj lub zog siab thaum khiav ntawm qhov kub siab. Daim foos ntawm kev sim no tau dhau los ua ib qho tseem ceeb hauv kev ua lag luam me, kom muaj kev pabcuam tshuab siab dua txias rau kev txhim kho kev ua tau zoo. Ib yam li ntawd, iso {{6892-2 muaj feem xyuam rau cov ntawv thov tseem ceeb hauv cov khoom siv hluav taws xob, thiab cov khoom siv petrochemical. Wherever metal fasteners, hardware, or structural components are expected to carry loads in hot environments, ISO 6892-2 enables a standardized determination and qualification of their important tensile properties.
Cov lus qhia dab tsi thiab cov tswv yim tuaj yeem pab txhim kho kuv qhov kev xeem?
Iso {6892-2}} piav ob txoj hauv kev ntawm cov khoom kub thiab ntsuas qhov ntsuas kub ntawm cov neeg siv tshuab, ob txoj kev los tswj hwm tus nqi siv thaum cov khoom ntiag tug tau txiav txim siab. Qhov no, nrog rau kev ua kom ntev tshaj plaws (± 20%), tsawg me me ntawm kev ntsuas tsis txaus ntseeg thiab sim ntsuas kev hloov pauv.
Txoj kev muaj kev haum tshwj xeeb tshaj yog qhov tshwj xeeb tshaj yog rau kev txo qis tsis meej thiab hloov pauv, yog li nws nyiam siv hauv kev lag luam aerospace. Nws siv txoj kev nqaim siab ntev rau qhov ntsuas qeeb qeeb uas txhim kho qhov ua kom muaj txiaj ntsig ntawm cov txiaj ntsig, tshwj xeeb tshaj yog thaum muaj kub dua. Iso 6892-2}}}}} Tseem muaj lwm txoj kev xaiv rau kev sib piv cov chav kub ntsuas tau ncaj qha rau tib tus nqi kub tib yam thiab thev taus. Qhov no yog lub hom phiaj ntawm txoj kev B.
Nyob rau hauv tus qauv Synex, ISO 6892-2}}}}}}}}} muaj cov hnoos qeev ntau yam hauv chav ntsuas kub tib yam hauv kev ntsuas kub (850 degree). Nws yog qhov tseeb ntawm cov nuj nqis uas muaj kev sib txawv-tus nqi rhiab tau nce nrog qhov kub siab dua.
