The requirement is often made in non-equilibrium statistical mechanics
that a transport equation should be derived as that which governs the
subdynamics relative to a (small) part of a (large) conservative
dynamical system close to equilibrium. We show that such a requirement
on the Markovian relaxation of a 1/2-spin imposes that this process be
described by a Bloch equation of a very specific form, which we call
standard. We show that this reduced dynamics is quasi-free if, and
only if, the relaxation time is maximally anisotropic.
