summary
Official TAPPI test method for determining the low- and high-shear viscosity of coating clay slurries.
description
TAPPI/ANSI T 648 om-14 provides a standardized procedure for evaluating the viscosity characteristics of coating clays and clay slurry shipments. The method covers sample preparation, dispersant optimization, solids adjustment, instrument calibration, low-shear and high-shear viscosity measurements, calculations, reporting requirements, precision, and viscometer operating principles. It is intended for laboratories, quality control teams, pigment and coating manufacturers, and technical professionals evaluating high-solids coating clay systems.
Application Scope: Suitable for measuring coating clay slurries prepared at high solids content, including predispersed slurry shipments and selected other pigments with appropriate procedural modifications.
