The characteristic of this viscometer was determined by measurement of viscosity of a NBS standard glass 711. The experimental results show that the applicability of this viscometer for the viscosity range from 10^6 to 10^<10> poises. There are two methods of measurement using the parallel plate viscometer. Namely, one is the static method in which temperature stays constant during each measurement and the other is the dynamic method in which temperature varies continuously through the measurement. From the comparison of two methods, it is concluded that the dynamic method gives a higher value of viscosity than that of the static method. The experimental errors due to temperature, the expansion of the mullite reference rod, and the expansion of the sample are discussed., 紀要類(bulletin), 619514 bytes}, pages = {1--10}, title = {<報文>平行板粘度計の試作}, volume = {38}, year = {1982} }
