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. |
