The NA48/2 experiment collected data in 2003 and 2004 with the main purpose to study direct CP violation in charged kaons decaying in three pions. Thanks to the huge statistics collected, other studies are also possible. In this paper two recent results, in the framework of QCD studies, are reported: the measurement of the K ± → π 0 e ± ν Form Factors and the first observation of the rare decay K ± → π ± π 0 e + e − .
