pasting parameters of time from onset of pasting to peak viscosity (Ptime);
temperature at which peak viscosity was reached (P temp);
peak viscosity (PV);
viscosity at the end of holding time at 95C (HPV);
breakdown (BD) = PV–HPV;
viscosity at the end of the hold time at 50C (CPV);
setback viscosity (SB) = CPV–HPV,
stability ratio (SR) = HPV/PV,
and setback ratio (SBR) = CPV/HPV.
