The Japanese Industrial Standards (JIS) for UV/Vis spectroscopy provide guidance for the use of spectrophotometers and accessories for qualitative and quantitative measurements. The JIS standards cover topics such as the measurement of absorbance and transmittance, wavelength accuracy, stray light, and photometric properties of samples. The JIS standards also provide guidelines for the selection and preparation of reference materials, sample handling and storage, and data analysis and reporting. These standards help ensure the accuracy, reproducibility, and comparability of measurements made with UV/VIS spectrophotometers in Japan. The JIS standards for UV/Vis spectroscopy are recognized both within Japan and internationally, making them important for ensuring the quality and reliability of data generated in research and industry.
