It is important to operate the R/S-SST+ at torque values that are within the R/S-SST+’s reliable range
of 30‰ (3% or 1.5mNm) to 1000‰ (100% or 50mNm). In creep testing, the minimum recommended
applied torque is 75‰ (3.75mNm).
D.3 A Few Tips To Get You Started
Creep test on fruit conserve. Angular dis-
placement (Phi, radians) is plotted against
time.
Short timescale response relates to elas-
tic behavior and long timescale response
relates to viscous behavior. So, a high
initial angular displacement indicates a
flexible “wobbly” gel structure while a
steep gradient at long timescales means
a product that creeps easily, that is, it has
a low low-shear viscosity.
