      The stated batch and specification values for the amount of substance concentration are valid at the time of bottling.
      The amount-of-substance concentration of this volumetric solution is analyzed by our quality control laboratory of Merck KGaA, Darmstadt, Germany according to DIN EN ISO/IEC 17025.
      The concentration is determined by volumetric titration and refers to 20°C.
      The amount-of-substance concentration of this volumetric solution is traceable to a primary standard reference material (SRM) 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), certified reference material according to ISO 17034, analyzed by our accredited calibration laboratory of Merck KGaA, Darmstadt, Germany according to DIN EN ISO/IEC 17025. The uncertainty is expressed as expanded measurement uncertainty with a coverage factor k=2 covering a confidence level of 95%.
      Note: The concentration of this volumetric solution decreases over time, due to its chemical properties. If high accuracy is expected, the titer, being a corrective factor that compensates for this effect as well as variations of equipment, personal handling, temperature and other laboratory conditions, must be determined directly after opening a new bottle and should be verified at regular intervals.
