Tsheb - saib daim iav yog ua raws li ntau lub teb chaws cov qauv thiab cov kev qhia tshwj xeeb thoob ntiaj teb. Hauv tsev, cov ntaub ntawv tseem ceeb yog GB 15084, "Kev ua tau zoo thiab kev teeb tsa rau cov khoom siv rau kev tsis pom kev tsis pom kev ntawm lub cev muaj zog," uas qhia txog cov ntsiab lus tseem ceeb xws li kev pom, kev xav, thiab lub vojvoog ntawm curvature. Cov qauv thoob ntiaj teb suav nrog UN Regulation No. 46 (UN R46), EU Cov Lus Qhia 2007/38/EC, thiab US Tsoom Fwv Teb Chaws Tsav Tsheb Kev Nyab Xeeb Tus Qauv No. 111 (FMVSS 111). Rau hluav taws xob sab nraum- tsom iav, kuj tseem ua rau ISO 16505, "Kev tsheb - Ergonomic thiab kev ua tau zoo ntawm Lub Koob Yees Duab Saib Xyuas Systems," thiab kev hloov kho rau ECE R46. Kev lag luam tus qauv QC/T 531, "Automotive rear-Saib Daim iav," qhia txog cov khoom lag luam, cov kev xav tau, thiab cov txheej txheem xeem. Ua ke, cov qauv no tsim lub hauv paus rau kev sim, ua kom muaj cai thiab sib piv ntawm cov txiaj ntsig.
Kev ntsuam xyuas cov txiaj ntsig kev xeem yog nyob ntawm cov txheej txheem nruj heev. Qhov chaw saib yuav tsum npog thaj tsam qhov muag tsis pom tau hais los ntawm cov qauv; Txoj kab rov tav ntawm qhov pom ntawm daim iav sab hauv yuav tsum yog tsawg kawg 20 degree, thaum thawj qhov chaw saib rau cov iav sab nrauv yuav tsum yog tsawg kawg 15 degree. Reflectance yuav tsum tau qhia qhov tsawg kawg nkaus ntawm 40% rau cov iav sab hauv nyob rau hauv hnub hom, nrog ib tug ntau ntawm 4% -40% rau anti- glare hom. Kev ntsuam xyuas cov duab zoo yuav tsum tau astigmatism qhov tseem ceeb nyob rau hauv qab 0.25 m⁻¹ thiab distortion yuav tsum tswj tsis pub dhau 7%. Hais txog mounting lub zog, daim iav brackets yuav tsum tiv taus ib tug zoo li qub load ntawm 400 N yam tsis tas yuav deformation. Kev ntsuam xyuas kev hloov pauv ib puag ncig xav kom cov iav qhov chaw tsis pom qhov pom ntawm qhov muag plooj, detachment, lossis tawg. Rau hluav taws xob rear{15}} tsom iav, duab latency yuav tsum tsis pub tshaj 60 ms, thiab kev daws teeb meem yuav tsum yog tsawg kawg yog 1 megapixel. Tag nrho cov khoom xeem yuav tsum ua raws li cov kev txwv; tsis ua raws li tej yam tseem ceeb ua rau cov khoom raug suav tias tsis yog{19}} ua raws.
