FIELD: test equipment.
SUBSTANCE: device includes two halves of a test specimen, each of which has support surface, onto which the above coating is applied, one counteracting test specimen having two support surfaces, and a test machine containing the first retaining system, the second retaining system and a stretching device. The second retaining system includes elastic return means providing the possibility of two halves of the test specimen being separated in the direction perpendicular to stretching direction in response to separation force applied with the counteracting test specimen to those two halves of the test specimen during the stretching cycle.
EFFECT: possibility of performing more differentiating test the results of which are highly correlative with actual stability evaluations in time of coatings of the blade root.
