摘　　要：为了考察实验室流出杯式黏度计校准能力,评估实验室测得结果与参考值的一致性,组织实施涂-4流出杯式黏度计校准能力验证计划,并评价能力验证结果。结果表明,2家实验室能力验证结果均为满意。通过分析涂-4流出杯式黏度计校准结果相对测量不确定度发现,需从校准环境、恒温时间和测量重复性等3方面考虑提高涂-4流出杯式黏度计校准结果准确性的措施。In order to investigate the calibration capability of the laboratory flow cup viscometer and assess the con-sistency between the laboratory measurement results and the reference values,the proficiency testing scheme for cali-brating TU-4 flow cup viscometer is organized and implemented,and the proficiency testing results are evaluated.The results showed that the proficiency testing results of two laboratories are satisfied.By analyzing the relative measure-ment uncertainty of the calibration results of TU-4 flow cup viscometer,it is found that measures to improve the accu-racy of the calibration results of TU-4 flow cup viscometer need to be considered from three aspects:calibration envi-ronment,constant temperature time,and measurement repeatability.
