Description	The paper concerns with the complex effects of free stream turbulence and surface roughness on the transitional intermittency inclusive of spot production rate in the zero pressure gradient boundary layer at low Reynolds number. The conditional analysis of the instantaneous wall friction is applied on time records made in transitional boundary layers originating on smooth surface or surface covered by sand paper (grits 60) under free stream with mean velocity 5 m/s, turbulence level 0.3 or 3 percent and dissipation length parameter from 3.8 mm up to 33.4 mm. Special procedures of measurement and evaluation are applied that allowed evaluations of turbulent and non-turbulent zone averages e.g. the mean durations of the wall friction stays in non-turbulent condition and turbulent condition, the conditionally averaged wall friction and histograms of the wall friction.
