This study evaluates and conıpares sonıe technological properties of Medium Density Fiberboards (MDF) made of softwood and lıardtvood nıixture furnishes manufactured in five milis located in Turkey. Tests vvere nıade on specimens conditioned at 20 ± 2 °C and 65 + 5 percent relative hunıidity. Analysis of variance and nıultiple-range test (Duncan) vvere carried out to evaluate test results. According to the results of this research, except for screvv holding, generally the other technological properties of paneis manufactured in the five milis were more than minimum Standard values of TS EN 64-5 and EMB industrial Standard.
