          Accreditation: This volumetric solution is certified according to DIN EN ISO/IEC 17025. KGaA, Darmstadt, Germany is accredited as calibration laboratory D-K-15185-01-00 for amount-of-substance concentrations in volumetric solutions according to DIN EN ISO/IEC 17025 by DAkkS (Deutsche Akkreditierungsstelle). The accreditation certificate can be found at www.sigmaaldrich.com/ISO17025.
          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 (article number 1.02400). This volumetric standard is certified by the accredited calibration laboratory of 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 calibration laboratory D-K-15185-01-00 of 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.
