摘要
在铁路物流园区内贸易结算时,用SCS-30 型静态电子汽车衡称量货物重量.为保障称量的货物重量准确,在介绍SCS-30 型静态电子汽车衡检定依据和测量方法的基础上,依据JJG 539-2016《数字指示秤》检定SCS-30 型静态电子汽车衡;建立测量模型,采用GUM法,评定SCS-30 型静态电子汽车衡在大于 20t且不大于 30t内各区间的检定结果不确定度.结果表明:SCS-30 型静态电子汽车衡检定结果不确定度小于等于最大允许误差的 1/3,满足量值传递要求,可用于称量货物重量.
Abstract
When settling trade in the railway logistics park, the SCS-30 type static electronic truck scale is used to weigh the weight of railroad cargoes. To ensure the accuracy of weighing goods, based on the introduction of the verifi-cation basis and measurement method of the SCS-30 type static electronic truck scale, the SCS-30 type static elec-tronic truck scale is verified according to JJG 539-2016 Digital indicating weighing instruments. The paper estab-lishes a measurement model and uses the GUM method to evaluate the uncertainty of the verification result of the SCS-30 type static electronic truck scale at each interval greater than 20 tons and not greater than 30 tons. The re-sults show that the uncertainty of the verification results of the SCS-30 type static electronic truck scale is less than or equal to 1/3 of the maximum allowable error, which meets the requirements for dissemination fo quantity value and can be used for weighing railroad cargoes.
