Cov hom ntawm ib puag ncig ntawm ib puag ncig thiab ua rau cov kev teeb tsa ib puag ncig uas muaj nyob hauv ntiaj teb' Ntawm lawv, tsis muaj tsawg tshaj li kaum os yam ua rau muaj kev cuam tshuam ntau dua rau kev siv thiab lub neej ntawm kev ua haujlwm yam xws li tshuab (khoom siv). Cov kws tshaj lij uas tau koom nrog kev tshawb fawb ntawm ib puag ncig cov xwm txheej ntawm cov khoom lag luam engineering txheeb tawm ntawm cov xwm txheej ib puag ncig uas muaj nyob rau hauv cov xwm txheej thiab cov xwm txheej ib puag ncig los ntawm tib neeg kev ua ub no mus rau hauv cov txheej txheem kev ntsuas thiab cov kev qhia tshwj xeeb los coj cov kev ntsuas ib puag ncig thiab kev ntseeg tau ntawm yam khoom engineering. Xws li coj cov khoom siv tub rog coj los ua cov kev ntsuam xyuas ib puag ncig GJB150-Tib neeg' s koom pheej ntawm Tuam Tshoj lub teb chaws tub rog tus qauv" Ib puag ncig kev kuaj rau kev siv tub rog" ;, GB2423 coj kev kuaj ib puag ncig ntawm hluav taws xob thiab khoom siv hluav taws xob-cov neeg' s koom pheej ntawm Tuam Tshoj Lub Teb Chaws Tuam Txhab Qauv" Qhia rau Kev Ntsuas Ib Puag Ncig rau Kev Siv Hluav Taws Xob thiab Hluav Taws Xob" ;, thiab lwm yam. Yog li no, thaum peb xaiv cov khoom siv kuaj ib puag ncig thiab kev ntseeg tau, lub hauv paus tseem ceeb yog kev ntsuas tshwj xeeb thiab ntsuas cov qauv ntawm cov khoom lag luam engineering.
Thib ob, txhawm rau ua qauv txheej txheem kev zam ntawm cov khoom kuaj ib puag ncig hauv cov cuab yeej kuaj thiab ua kom paub tseeb kev tswj hwm ntawm qhov ntsuas ib puag ncig, lub koomhaum saib xyuas lub teb chaws thiab ntau lub tuam txhab kev lag luam tseem tau tsim cov txheej txheem pov thawj rau cov khoom kuaj ib puag ncig thiab cov cuab yeej ntsuas. Piv txwv, National Standard ntawm Cov Neeg' s koom pheej ntawm Tuam Tshoj GB5170" Cov hau kev rau kev txheeb xyuas cov ntsiab lus ntawm cov khoom kuaj ib puag ncig ntawm cov khoom kuaj rau cov khoom siv hluav taws xob thiab hluav taws xob", thiab JJG190-89" Kev cai rau Kev Tshawb Xyuas Kev Tshawb Fawb ntawm Kev Siv Hluav Taws Xob Kev Ntsuam Xyuas Lub Txheeb Xyuas Lub Tshuab" tau tshaj tawm thiab siv los ntawm Lub Xeev Pawg Saib Xyuas Haujlwm Thawj Saib Xyuas Chav Haujlwm. Cov txheej txheem pov thawj no tseem yog lub hauv paus tseem ceeb rau xaiv cov khoom siv ib puag ncig thiab kev ntseeg tau. Cov cuab yeej sim uas ua tsis tau raws li cov cai ntawm cov txheej txheem kev lees paub no tsis tau tso cai siv.
