Test program consisting of three intervals, preset:

1 st interval: pre-shear phase (for t = 3 min): at γ ̇ = 5 s-1 = const

2 nd interval: rest phase (for t = 1 min): at γ ̇ = 0

3 rd interval: upward shear rate ramp

(in t = 2min): γ ̇ = 0 to γ ̇ max

at γ ̇ max = 100 s-1 (or, for a rigid consistency:

at γ ̇ max = 20 s-1 only)

Analysis: viscosity value at γ ̇ = 50 s-1 (or at 10 s-1, respectively)
