| The concentration of this volumetric solution was determined with volumetric standard benzoic acid (article number 1.02401). The determined titer at 20°C was 1.000 with an expanded measurement uncertainty of ± 0.004 (k=2 coverage factor for 95% coverage probability). The certified value is traceable to primary standard NIST SRM 350b (NIST: National Institute of Standards and Technology, USA) by means of volumetric standard benzoic acid, measured in the accredited calibration laboratory of Merck KGaA, Darmstadt, Germany in accordance to DIN EN ISO/IEC 17025. |
