1. Cov txheej txheem tsim khoom hloov pauv los ntawm kev tsim cov duab kos rau cov khoom, thiab nws yuav tsum tau mus dhau ntawm cov txheej txheem tsim khoom. Tag nrho cov txheej txheem ntawm kev hloov cov ntaub ntawv raw lossis cov khoom ua tiav rau hauv cov khoom feem ntau hu ua cov txheej txheem tsim khoom. Cov txheej txheem ntau lawm feem ntau suav nrog:
(1) Cov txheej txheem kev npaj muaj xws li kev soj ntsuam kev lag luam, kev kwv yees, kev txheeb xyuas cov khoom tshiab, cov txheej txheem tsim, kev tshuaj xyuas tus qauv, thiab lwm yam ua ntej cov khoom yuav muab tso rau hauv ntau lawm.
(2) Los yog cov txheej txheem thev naus laus zis hais txog cov txheej txheem ncaj qha hloov qhov loj me, cov duab, kev sib txuas ntawm qhov chaw, qhov roughness los yog cov khoom ntawm cov khoom siv raw thiab cov khoom ua tiav los ua cov khoom tiav. Xws li kev tsim ua kua, yas sib sau, vuam, hmoov sib sau, txiav, kev kho cua sov, kev kho deg, sib dhos, thiab lwm yam., txhua yam yog cov txheej txheem. Cov txheej txheem tsim nyog tau sau rau hauv ib daim ntawv qhia txog kev tsim khoom, cov ntaub ntawv no yog hu ua cov txheej txheem specification.
(3) Cov txheej txheem tsim khoom pabcuam yog hais txog cov haujlwm pabcuam tsim nyog tsim nyog los xyuas kom meej tias kev ua haujlwm ib txwm muaj ntawm cov txheej txheem tsim khoom.
(4) Cov txheej txheem kev pabcuam tsim khoom yog hais txog cov txheej txheem ntawm lub koom haum, kev thauj mus los, kev cia khoom, kev cia khoom, kev ntim khoom thiab ntim khoom thiab muag khoom ntawm raw khoom.
