In case of contact with eyes, rinse immediately with plenty of water and seek medical advice.Wear suitable gloves and eye/face protection.In case of accident or if you feel unwell, seek medical advice immediately (show the label where possible).运输信息 申报（铁路和陆路）ADR、RID UN 1824 Natriumhydroxidlösung, 8, II 申报（空运）IATA-DGR UN 1824 SODIUM HYDROXIDE SOLUTION, 8, II 申报（海运）IMDG-代码 UN 1824 SODIUM HYDROXIDE SOLUTION, 8, II, Segregation Group: 18 (Alkalis) 规格 规格 Concentration after dilution to 1 liter: c(NaOH) = 0.5 mol/l Amount-of-substance concentration 0.5000 mol/l The concentration of this solution was determined with hydrochloric acid standard solution (Merck article number 1.09057) standardized against volumetric standard Tris(hydroxymethyl)aminomethane (Merck article number 1.02408). The determined titer at 20°C was 1.000 with an expanded measurement uncertainty of ± 0.004 (k=2 coverage factor for 95% coverage probility). The certified value is traceable to primary standard NIST SRM 723e (NIST: National Institute of Standards and Technology, USA) by means of volumetric standard Tris(hydroxmethyl)aminomethane, measured in the accredited calibration l
