Specification Test Results

Form liquid
Amount-of-substance concentration 0.0995 - 0.1005
Measurement uncertainty +/- 0.0003
Traceability NIST SRM
The concentration is determined by volumetric titration and refers to 20°C.
The certified value is traceable to a primary standard from the National Institute of Standards and Technology, Gaithersburg, USA (NIST SRM 682 zinc) by means of volumetric standard zinc (Art. 1.02409).
This volumetric standard is certified by the accredited calibration laboratory of Merck KGaA, Darmstadt, Germany according to DIN EN ISO 17025.
The uncertainty is expressed as expanded measurement uncertainty with a coverage factor k=2 covering a confidence level of 95%. All measurements are carried out in the laboratory of Merck KGaA, Darmstadt, Germany.
