Comparative Analysis of Accuracy Grades in Dynamic Weighing (WIM): OIML R134-1 vs. GB/T 21296.1-2020      Introduction OIML R134-1 and GB/T 21296.1-2020 are both standards that provide specifications for dynamic weighing systems (WIM) used for highway vehicles. OIML R134-1 is an international standard issued by the International Organization of Legal Metrology, applicable globally. It sets out requirements for WIM systems in terms of accuracy grades, permissible errors, and other technical specifications. GB/T 21296.1-2020, on the other hand, is a Chinese national standard that offers comprehensive technical guidelines and accuracy requirements specific to the Chinese context. This article aims to compare the accuracy grade requirements of these two standards to determine which one imposes stricter accuracy demands for WIM systems. 1.        Accuracy Grades in OIML R134-1 1.1 Accuracy Grades Vehicle Weight : Six accuracy grades: 0...
