This document specifies the general procedure to be followed in determining the dynamic viscosity of unpigmented coating materials, such as paints, varnishes and related products, as well as binders at a shear rate range between 9 000 s^(-1) and 12 000 s^(-1). It describes an absolute viscosity measurement with cone-plate measuring geometry at high shear rates. The measured value gives information about the resistance offered by the material to brushing, spraying and roller coating during application. The method specified in this document is suitable for all paints and varnishes whether they are Newtonian in behaviour or not. For materials containing dispersions of large particles, the measuring geometry is expected to be adapted.
