Classical Test Method T 697 "Accelerated test for viscosity stability of clay slurries" is due for its ten-year review. Poor response to the first two ballots has led to a number of Standard-Specific Interest Group (SSIG) members being in danger of being dropped from the SSIG due to lack of response.
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.
In order for this method to remain active, new SSIG members must be recruited to participate in the balloting process. If you have an interest in this method and would like to join the SSIG, please send a message to standards@tappi.org before August 6, 2012 (the due date for the ballot on Draft 3). When you join the SSIG before August 6, you will be sent the Draft 3 ballot to vote on.
