O-ring cord yog ib hom roj hmab npog hlau hlua uas feem ntau siv hauv engineering thiab kev tsim kho. Nws yog tus cwj pwm los ntawm nws txoj kab hla hla, nrog cov roj hmab npog uas muab kev tiv thaiv rau cov hlua hlau. Tus qauv rau O-ring qaum yog ISO 10694: 2007, uas qhia meej txog cov khoom siv, kev tsim kho, kev ua haujlwm, thiab kev sim ntawm O-ring cords.
TS EN ISO 10694: 2007 yog cov qauv dav dav uas qhia txog cov kev qhia tshwj xeeb rau O-ring cords, suav nrog lawv qhov ntev, cov khoom siv, cov txheej txheem tsim kho, thiab cov txheej txheem kuaj. Tus qauv tsim los xyuas kom meej qhov zoo thiab kev ua tau zoo ntawm O-ring cords siv nyob rau hauv ntau yam kev siv, xws li nyob rau hauv kev tsim kho ntawm cov choj, tunnels, vaj tse, thiab lwm yam qauv.
Raws li ISO 10694: 2007, O-ring cords yuav tsum tau ua los ntawm cov khoom siv roj hmab zoo uas muab cov elasticity zoo, hnav tsis kam, thiab huab cua tsis kam. Cov tub ntxhais hlau yuav tsum tau ua los ntawm cov hlau muaj zog hlau uas sib tw ua ke los tsim cov tub ntxhais muaj zog thiab ruaj khov. Cov roj hmab npog yuav tsum muaj kev tiv thaiv zoo rau cov tub ntxhais hlau thiab muab cov rwb thaiv tsev txaus rau kev siv hluav taws xob.
Tus qauv tseem qhia txog cov txheej txheem kuaj rau O-ring cords, suav nrog kev sim tensile, kev sim compression, kuaj dabtsi yog khoov, thiab ntsuas rwb thaiv tsev. Cov kev ntsuam xyuas no yog tsim los xyuas kom meej qhov zoo thiab kev ua tau zoo ntawm O-ring cords nyob rau hauv ntau yam kev siv nyob rau hauv ntau yam kev mob.
Los ntawm kev ua raws li cov lus qhia tshwj xeeb tau teev tseg hauv ISO 10694: 2007, cov tuam txhab tsim khoom tuaj yeem tsim O-ring cords uas ua tau raws li tus qauv thiab muab kev ua tau zoo hauv ntau yam engineering thiab kev tsim kho. Cov qauv no ua kom ntseeg tau tias O-ring cords muaj kev nyab xeeb, txhim khu kev qha, thiab tsim nyog rau lawv txoj kev siv.
ISO 10694: 2007 yog tus qauv uas qhia meej txog cov khoom siv ntawm O-ring qaum, kev tsim kho, kev ua haujlwm, thiab kev sim. Los ntawm kev ua raws li tus qauv no, cov tuam txhab tsim khoom tuaj yeem tsim cov khoom zoo O-ring cords uas ua tau raws li cov lus qhia tshwj xeeb rau kev siv ntau yam engineering thiab kev tsim kho. Qhov no ua kom muaj kev nyab xeeb thiab kev ntseeg siab ntawm O-ring cords hauv cov qauv tseem ceeb thiab cov tshuab siv tshuab.
