FIELD: testing equipment.
SUBSTANCE: device has base, sample and counter-sample holders, sample loading unit and holder drive. Device is provided with sample and counter-sample relative movement mechanism made in form of pair of gear-wheels to one of which the counter-sample is fastened. The latter is made in form of slot bushing. Sample holder is made in form of slot shaft connected with shaft, which shaft enters hole of slot bushing of gear-wheel. Samples are fastened to side surfaces of shaft's slots disposed uniformly along the circle. External side faces of any sample having contact with counter-sample are made at angle of α relatively axis of slot shaft being within 0°-0°17' boundaries.
EFFECT: widened functional capabilities; improved efficiency of process.
