Abstract. We develop a general framework for the discussion of detailed balance and analyse its microscopic background.
We find that there should be two additions to the well-known T- or PT-invariance of the microscopic laws of motion:
1. Equilibrium should not spontaneously break the relevant T- or PT-symmetry.
2. The macroscopic processes should be microscopically distinguishable to guarantee
persistence of detailed balance in the model reduction from micro- to macrokinetics.
We briefly discuss examples of the violation of these rules and the corresponding violation of detailed balance.
