ActiveAutomatic instruments for weighing road vehicles in motion—Part 5：Crystal quartz type
动态公路车辆自动衡器 第5部分：石英晶体式
Application Summary AI generated
This standard specifies the metrological and technical requirements for crystal quartz type automatic weigh-in-motion (WIM) instruments used to weigh road vehicles without stopping. It is applied in highway toll collection, traffic monitoring, and overload enforcement systems where the sensor technology relies on quartz crystal piezoelectric elements to measure axle loads and vehicle weight. The standard ensures accuracy and reliability for high-speed, dynamic weighing in real-world traffic conditions.
