Dimensional kam rau ua:
- Txhua pawg yeeb nkab yuav tsum tau hnyav ib tus zuj zus. Qhov sib txawv ntawm qhov hnyav thiab qhov hnyav theoretical yuav tsum tsis pub tshaj 15% (hnyav) lossis 5% (qis dua) kom ntseeg tau tias cov yeeb nkab pawg tuaj yeem tiv taus cov qauv tsim.
- Qhov sib txawv ntawm cov yeeb nkab pawg ntawm txoj kab uas hla ntawm cov txheej txheem sab nraud yuav tsum tsis pub tshaj 1% kom ntseeg tau qhov tseeb ntawm kev teeb tsa thiab siv.
- Kuj tseem muaj cov kev cai sib txawv ntawm cov yeeb nkab phab ntsa thickness kom ntseeg tau tias tag nrho lub zog thiab ruaj khov ntawm cov yeeb nkab pawg.
