摘要
介绍500 kg^2 000 kg F1等级砝码标准装置的组成,并进行不确定度分析,说明该装置可以满足检定500 kg^2 000 kg F2等级砝码的要求。500 kg^2 000 kg F1等级砝码标准装置的建立可以完善轨道衡计量量值传递系统,保障全国轨道衡计量量值传递系统的准确可靠。
the Paper introduces the composition of 500 kg^2 000 kg Class-F1 standard weight and make an uncertainty analysis,then explains that the device can meet the requirement for 500 kg^2 000 kg Class-F2 weights.The setup of 500 kg^2 000 kg standard Class-F1 weight can improve the weighing-in-motion bridge measurement value traceability system,thus ensuring the accuracy and reliability in the national weighing-in-motion bridge measurement value traceability system.
