We report the results of the measurements and analysis of the pulse broadening dueto interstellar scattering on 43 pulsars at 102 MHz. This is the largest uniform sample of directmeasurements of pulsar scattering τsc , which make it feasible to analyze the dependence of this valueon other pulsar parameters. The measured dependence of τsc on dispersion measure τsc(DM) =40(DM/100)2.1 is close to theoretically expected relation τsc(DM) α DM 2. A frequency dependenceof the scattering pulse broadening is weaker than commonly accepted τsc α v-4.4.
