Abstract: The scaling properties at low $x$ of the proton DIS cross section and itscharm component are analyzed with the help of the quality factor method.Scaling properties are tested both in the deep inelastic scattering data and inthe structure functions reconstructed from CTEQ, MRST and GRV parametrisationsof parton density functions. The results for DIS cross sections are fullycompatible between data and parametrisations. Even with larger error bars, thecharm component data favors the same geometric scaling properties as the onesof inclusive DIS. This is not the case for all parametrisations of the charmcomponent.
