摘要
Abstract
High-precision weights are a type of weighing instrument with high precision and small errors,which are usually used in occasions where the requirements for quality or weight accuracy are extremely high,such as scientific laboratories,pharmaceutical industry,metrology and testing,and other fields.Ensuring the accuracy and reliability of high-precision weight values is of great significance in ensuring product quality,and improving product performance and stability.In this paper,a measurement model is established for the measurement process of E2 standard weights,and the verification and extended uncertainty are evaluated according to the verification procedure JJG 99-2022,Weights.The verification results show that the agreed mass value of the measured weight meets the requirements of the regulations,and the extended uncertainty calculation results show that the measurement process is accurate and reliable.关键词
