The critical indices \alpha', \beta, \gamma' and \delta of the Quark GluonBags with Surface Tension Model with the tricritical endpoint are calculated asfunctions of the usual parameters of this model and two newly introducesparameters (indices). They are compared with the critical exponents of othermodels. It is shown that for the newly introduced indices \chi = 0 and \xi^T <1 there is a branch of solutions for which the critical exponents of thepresent model and the statistical multifragmentation model coincide, otherwisethese models belong to different universality classes. It is shown that forrealistic values of the parameter \varkappa the critical exponents \alpha',\beta, \gamma' and \delta of simple liquids and 3-dimensional Ising model canbe only described by the branch of solutions in which all indices except for\alpha' correspond to their values within the statistical multifragmentationmodel. The scaling relations for the found critical exponents are verified andit is demonstrated that for the standard definition of the index \alpha' theFisher and Griffiths scaling inequalities are not fulfilled for some values ofthe model parameters, whereas the Liberman scaling inequality is always obeyed.Although it is shown that the specially defined index \alpha'_s recovers thescaling relations, another possibility, an existence of the non-Fisheruniversality classes, is also discussed.
