DIN EN ISO 12058-1:2018-05

This document specifies the general principles of a method, using an inclined-tube falling-ball viscosimeter, 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 behavior.
