The DIN_DIN_EN standards help ensure that measurements made with UV/VIS spectrophotometers are accurate, reproducible, and comparable, both within Germany and across the European Union.
DIN_DIN_EN Standards Standard Norms and Instruments for UV/Vis Spectroscopy
UV/Vis Spectrophotometric Method for Accurate Measurements
DIN_DIN_EN standards are German national standards that have been adopted as European Standards (EN) and then harmonized with International Organization for Standardization (ISO) standards.
The DIN_DIN_EN standards for UV/Vis spectroscopy provide guidance on the technical specifications, calibration procedures, and performance verification tests of spectrophotometers and accessories.
These standards cover topics such as the measurement of photometric properties, stray light, and absorbance accuracy, as well as the selection and calibration of reference materials, sample preparation and handling, and data analysis and reporting.
