Plastics - Determination of viscosity using a falling-ball viscometer - Part 1: Inclined-tube method (ISO 12058-1:1997); German version EN ISO 12058-1:2002
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?to 250000 mPa?(temperature range - 20 ?to + 120 ? 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.
