Irritating to eyes and skin.运输信息 申报（铁路和陆路）ADR、RID UN 2790 Essigsäure, Lösung, 8, III 申报（空运）IATA-DGR UN 2790 ACETIC ACID SOLUTION, 8, III 申报（海运）IMDG-代码 UN 2790 ACETIC ACID SOLUTION, 8, III, Segregation Group: 1 (Acids) 规格 规格 Concentration after dilution to 1 liter: c(CH₃COOH) = 0.1 mol/l Amount-of-substance concentration 0.100 mol/l The concentration of this solution was determined with sodium hydroxide standard solution (Merck article number 1.09141) standardized against volumetric standard potassium hydrogen phthalate (Merck article number 1.02400). 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 84L (NIST: National Institute of Standards and Technology, USA) by means of volumetric standard potassium hydrogen phthalate, measured in the accredited calibration laborato
