000291405 520__ $$aThe NA48/2 Collaboration at CERN has accumulated an unprecedented statistics of rare semileptonic four-body $K_{e4}$ decay modes $K^{\pm}\rightarrow\pi^+\pi^-e\nu$ and $K^{\pm}\rightarrow\pi^0\pi^0e\nu$, with nearly 1$\%$ background contamination. Final results from the analyses of the full $K_{e4}$ data samples are described. The most accurate measurements to date of form factors and branching ratios have been achieved by NA48/2, bringing new inputs to low energy QCD description and stringent tests of predictions from Chiral Perturbation Theory and Lattice QCD.
