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.
