Raws li EN545, cov cim ntawmcov kav hlau ductilethiab cov khoom siv yuav tsum pom tseeb, ruaj khov thiab suav nrog cov hauv qab no:
Daim kab xev cim yeeb nkab DI
- Cov ntawv cim yeeb nkab
- DS: Lub Npe Chaw Tsim Khoom lossis Lub Cim Lag Luam
- ISO2531: Tus lej txheem kev siv (piv txwv li, EN545)
- DN1000: Nominal Txoj Kab uas hla
- C25: Kev Ntsuas Siab
- L6000: Siv Tau Ntev
