介绍了熔体流动速率仪各参数不确定度评定方法,便于在实际检定校准工作中应用。该不确定度评定方法包含了规程规定的温度、时间、负荷(电子秤)、质量(电子天平)和熔体流动速率等参数。评定的不确定度已在实际检定校准工作中应用,通过了实践检验,满足实际检定校准工作的要求,为全参数检定校准熔体流动速率仪提供了一种不确定度评定方法的参考。
The method of evaluating the uncertainty of each parameter of the melt flow rate meter is introduced, which is convenient for the application in the actual verification and calibration work. This uncertainty assessment method includes parameters such as temperature, time, load (electronic scale), mass (electronic balance) and melt flow rate specified in the protocol. The uncertainty of assessment has been applied in the actual verification and calibration work, and has passed the practice test to meet the requirements of actual verification and calibration work. It provides a reference for the method of calibration of all parameters for the calibration of melt flow rate measurement.
