DIN EN ISO 12058-1:2002-12

This standard 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 250000 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.
