| Determination method: Titration with lead(II)perchlorate solution. The content of this solution was determined with lead(II)perchlorate solution standardized against volumetric standard zinc (article number 1.02409). The expanded measurement uncertainty is ± 0.4 % (k=2 coverage factor for 95% coverage probability). The certified value is traceable to primary standard NIST SRM 682 (NIST: National Institute of Standards and Technology, USA) by means of volumetric standard zinc, measured in the accredited calibration laboratory of Merck KGaA, Darmstadt, Germany in accordance to DIN EN ISO/IEC 17025. | |
