(1) Cov tsim stamping qhov chaw yuav tsum ua raws li cov khoom siv thiab kev ua haujlwm, thiab yooj yim rau kev sib sau thiab kho.
(2) Cov khoom siv stamping tsim yuav tsum ua kom muaj txiaj ntsig zoo rau kev siv cov khoom siv hlau, txo cov ntau yam thiab cov khoom siv tshwj xeeb, thiab txo cov khoom siv ntau li ntau tau. Yog tias tso cai, cov khoom siv nrog tus nqi qis yuav tsum tau siv los ua cov khoom seem uas tsis muaj pov tseg thiab tsis muaj pov tseg kom deb li deb tau.
(3) Cov tsim stamping qhov chaw yuav tsum yooj yim hauv cov duab thiab tsim nyog hauv cov qauv, uas yog qhov tsim nyog rau kev ua kom yooj yim ntawm cov pwm pwm thiab cov txheej txheem. Ntawd yog, qhov tsawg kawg nkaus thiab yooj yim stamping txheej txheem yog siv los ua kom tiav cov txheej txheem tag nrho, thiab lwm txoj kev siv los txo kev ua haujlwm. Nws kuj yog qhov tsim nyog rau kev ua haujlwm stamping, thiab nws yooj yim rau kev teeb tsa thiab paub txog kev siv tshuab thiab tsis siv neeg ntau lawm, txhawm rau txhim kho cov khoom lag luam.
(4) Raws li qhov ua tau zoo ntawm kev siv ib txwm siv, qhov tsim stamping qhov chaw yuav tsum muaj qis dua ntawm qhov tseeb qib thiab qib roughness ntawm qhov chaw kom deb li deb tau, uas yog qhov tsim nyog rau kev hloov khoom, txo cov khoom pov tseg thiab ua kom cov khoom ruaj khov.
(5) Cov tsim stamping qhov chaw yuav tsum ua kom zoo rau kev siv cov khoom siv uas twb muaj lawm, cov txheej txheem cov khoom siv thiab cov txheej txheem ntws los ua cov txheej txheem ntau li ntau tau, thiab txuas ntxiv ntawm kev pab cuam lub neej ntawm cov neeg tuag.
