Thaum yuav cov khoom siv dag zog sab nraum zoov, muaj ntau yam los txiav txim siab kom ntseeg tau tias cov cuab yeej muaj kev nyab xeeb, ruaj khov, thiab tsim nyog rau cov neeg siv khoom xav tau. Nov yog qee yam tseem ceeb uas yuav tsum nco ntsoov:
Durability: Cov cuab yeej tawm dag zog sab nraum zoov raug rau ntau yam huab cua, suav nrog nag, daus, thiab hnub ci. Yog li ntawd, nws yog ib qho tseem ceeb uas yuav tau xaiv cov cuab yeej ua los ntawm cov khoom siv ruaj khov uas tuaj yeem tiv taus cov xwm txheej no.
Kev nyab xeeb: Kev nyab xeeb yog qhov tseem ceeb thaum nws los txog rau cov khoom siv dag zog sab nraum zoov. Xyuas kom meej tias cov cuab yeej tau tsim thiab sim ua kom tau raws li cov qauv kev nyab xeeb, suav nrog ASTM thiab CPSC.
Kev tu: Cov cuab yeej tawm dag zog sab nraum zoov xav tau kev saib xyuas tsis tu ncua kom ntseeg tau tias nws tseem nyob hauv kev ua haujlwm zoo. Xaiv cov cuab yeej uas yooj yim los tswj, thiab xyuas kom meej tias koj muaj txoj kev npaj tu vaj tse nyob hauv qhov chaw.
Nqi: Cov khoom siv dag zog sab nraum zoov tuaj yeem sib txawv ntawm tus nqi. Thaum xav txog cov peev nyiaj, nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias cov khoom siv qis tshaj plaws yuav tsis yog tus nqi zoo tshaj plaws nyob rau lub sijhawm ntev. Cov cuab yeej pheej yig dua tuaj yeem xav tau kev saib xyuas ntau zaus thiab hloov pauv, thaum cov khoom siv kim dua tuaj yeem siv tau ntev dua thiab xav tau kev saib xyuas tsawg dua.
