In this work we analize the classicality conditions that must be satis
fied to have an effective stochastic approach, in the framework of war
m inflation scenarios. The radiation temperature at the end of inflati
on is of the order of 10(14) GeV, for an scalar field with mass m simi
lar to (10(-4)-10(-5)) M-p, and the energy fluctuations decreases with
the time. (C) 1998 Published by Elsevier Science B.V. All rights rese
