Specification Test Results
Form | liquid |
Amount-of-substance concentration | 0.3332 - 0.3350 |
Measurement uncertainty | +/- 0.0010 |
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 84 potassium hydrogen phthalate) by means of volumetric standard potassium hydrogen phthalate(Art. 1.02400). | |
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. | |
Note: The titer is a correction factor to correct for variations of the volumetric solution, the titration equipment, the temperature and other laboratory conditions. | |
For correct titration results it is recommended to determine a titer with the laboratory specific equipment and under laboratory specific conditions directly after opening a new bottle and at regular time intervals. |
