1st interval (for t = 60 s, with 5 measuring points): at γ ̇ = 0.1 s-1 = const

2nd interval (for t = 30 s, with 5 points): at γ ̇ = 1000 s-1 = const

3rd interval (for t = 180 s, with 50 points or more): at γ ̇ = 0.1 s-1 = const again

Exactly the same shear profile has to be preset for each individual test if thixotropy values of different tests are to be compared, and that counts for all parameters: shear rates, number of measuring points, and duration of the test intervals.
