In this article, we will establish sufficient conditions for the interval oscillation of fractional partial differential equations of the form

It is based on the information only on a sequence of subintervals of the time space  rather than whole half line. We consider f to be monotonous and non monotonous. By using a generalized Riccati technique, integral averaging method, Philos type kernals and new interval oscillation criteria are established. We also present some examples to illustrate our main results.
