This article discusses the research work on sucrose solution standard substances, including the identification and selection of raw materials in the development process of this series of standard substances, the preparation method of standard substances, the determination method of characteristic values, uniformity testing experiments, stability testing experiments, and constant value measurement work. After investigation, it was found that the series of standard substances remained stable within 6 months. To obtain the uncertainty of this series, the various uncertainty components introduced by sample uniformity, measurement dispersion, and other factors were analyzed and determined. Finally, the relative expanded uncertainties of the sucrose solution standard substance with standard values of 1.00% and 5.00% were determined to be 1.0% and 1.0%, respectively. This series of standard substances has excellent metrological characteristics and application prospects, and can be used for research and inspection in related fields of food, medicine, and chemical products. It helps to achieve metrological calibration of related inspection instruments (such as sugar meters), evaluation of analysis methods, or confirmation of sugarcane content detection and detection methods in various substrates, and is expected to assist in unifying sucrose related values.
