DAΦNE will offer an opportunity to check Chiral Perturbation Theory predictions at higher order. In this talk I have selected a few topics for which it is expected that the lowest order calculation will not be sufficient in order to compare with the experimental results. In particular I will discuss pion pair production in two photon collisions, Kl3 and Kl4 decays.
