  The critical indices alpha', beta, gamma' and delta of the Quark Gluon Bags
with Surface Tension Model with the tricritical and critical endpoint are
calculated as functions of the usual parameters of this model and two newly
introduced parameters (indices). The critical indices are compared with that
ones of other models. The universality class of the present model with respect
to values of the model parameters is discussed. The scaling relations for the
found critical exponents are verified and it is demonstrated that for the
standard definition of the index alpha' some of them are not fulfilled in
general case. Although it is shown that the specially defined index alpha'_s
recovers the scaling relations, another possibility, an existence of the
non-Fisher universality classes, is also discussed.
