Experimental results on $K_L$ decays

Recent measurements by the NA48 at CERN of selected $K_L$ decays are presented. These are the branching ratios and form factors for channels $K_L\to π^{\pm}π^0\e^{\mp}ν_e$ (final result), $K_L\toπ^{\pm}e^{\mp}ν_e$ and $K_L\to e^+e^-e^+e^-$ (preliminary results).
