Page 50: Addendum
byko visc RT Lite BYK-Gardner GmbH Addendum In order to get the best results possible, a number of factors have to be considered when taking measurements with the byko-visc RT. Firstly, there are instrument specific factors. These include the spindle geometry, accuracy and sample volume size. Secondly, there are fluid dependent factors.
Page 51 BYK-Gardner GmbH byko visc RT Lite We are aware, that using the spindle guard is sometimes not practical for customers. It is absolutely possible to remove it, and or use smaller sample sizes than 500 mL. The instrument will keep measuring accurate torque values. However, these will not translate into accurate viscosity readings, because the boundary conditions have changed.
Page 52: Spindle Geometries
byko visc RT Lite BYK-Gardner GmbH 9.1.3 Spindle Geometries Viscometer readings are dependent on several different factors. Most substances are found to be non-Newtonian. These are dependent on the shear rate and spindle geometry conditions. These factors can be found in the following Tables 2-4. Non-Newtonian fluids change their viscosity values dependent on the shear rate.
