数字指示轨道衡计量性能及检定方法分析

Analysis for Metrology Performance and Verification Method of Digital Indicating Rail-weighbridges

结合近年来JJG 781—2019《数字指示轨道衡》的实施情况,对JJG 781—2019采用国际建议情况、主要内容的理解、不同型式数字指示轨道衡的检定方法,以及计量标准器的确定等实施过程中的关键问题进行分析,为更好地实施和应用JJG 781—2019提供参考。

Based on the implementation of JJG 781—2019 Digital indicating rail-weighbridges in recent years,this paper analyzes the key issues in the implementation process of JJG 781—2019,including the adoption of international recommendations,understanding of the main content,verification methods for different types of digital indicating rail-weighbridges,and determination of measurement standards.This provides reference for the implementation and application of JJG 781—2019.
