Abstract
Rotational rheometer was used to measure the shear viscosity of a liquid reference material of viscosity named GBW13604. The influences of heat balance time, bath temperature, environment temperature and sampling volume on results of measurements were investigated. Furthermore, a comparison of accuracy and repeatability of shear viscosity results between two commonly used systems with cone-plate and coaxial cylinder geometry was performed. Rheological tests indicate that the coaxial cylinder method is applicable to tests requiring high accuracy, while the cone-plate method is suitable for measurements that demand low sampling volume and fast speed.
