FIELD: physics.
SUBSTANCE: invention refers to a test piece for testing of highly elastic materials on friction and deterioration. The sample is executed in the form of a square parallelepiped with a flat working surface, a fastening corbel and a ledge on the mentioned surface in the form of a hemisphere, semicylinder or a cone. The part of the sample in the form of a square parallelepiped with a fastening corbel is executed from rubber with content of the vulcanising agent - sulfur - 25-50 wt %, and the mentioned ledge is executed from the mentioned above rubber with 0.2-5.0 wt % sulfur content.
EFFECT: reliability increase of test results of highly elastic materials on friction and deterioration.
