Abstract. It is widely believed that the critical properties
of several planar lattice models, like the Eight Vertex or the
Ashkin-Teller models, are well described by
an effective Quantum Field Theory obtained as formal scaling
limit. On the basis of this
assumption several extended scaling relations among their
indices were conjectured. We prove the validity of some of them, among
which the ones by Kadanoff and
by Luther and Peschel.
