Accelerated test for viscosity stability of clay slurries, Test Method T 697 cm-01

This method describes a procedure for predicting the relative storage life of aqueous kaolin clay dispersions by measuring viscosity increase during storage at an elevated temperature.

*Viscosity is measured by a low-shear rotating spindle apparatus as described in Appendix A of TAPPI T 648 “Viscosity of Coating Clay Slurry.”

*This procedure does not describe methods for determining dispersant requirements of clays, nor does it describe dry clay slurrying procedures. It describes only the testing procedures for a given clay slurry.

*This procedure does not describe a method for determining the viscosity stability of other pigment slurries or for coating colors; however, this method may be useful for such systems.
