Measurements of flows approaching the highest Reynolds-numbers achievable in laboratory conditions in the SHREK experiment shall be performed. With these data it shall be investigated if the integral fluctuations theorem, as a new basic non-equilibrium thermodynamical law, still holds. The consequences for a stochastic description of the turbulent disorder shall be investigated focusing on the following questions:

- Can an approach to a universal high Re-number state be seen?

- Are scaling breaking contributions remaining significant?

Besides the change of the Reynolds-number, the case of superfluid turbulence shall be considered to perform a stochastic comparison to the above-mentioned points.
