Annotation of standard text ČSN EN ISO 12058-1 (640348):
This document specifies the general principles of a method, using an inclined tube falling ball viscometer, for determining the viscosity of polymers and resins in the liquid emulsified or dispersed state. It is intended for application to liquids over a viscosity measurement range of 0,6 mPa˙s to 250 000 mPa˙s (temperature range -20 °C to +120 °C) for which the shear stress and shear rate are proportional, i.e. the viscosity is independent of the shear rate. This ideal behaviour is commonly known as Newtonian behaviour. If a liquid differs significantly from this behaviour, different results can be obtained with the different balls of a falling ball viscometer or from viscometers with different geometries, such as capillary and rotational viscometers
