FIELD: material testing. SUBSTANCE: method of manufacture of sample for adhesion strength testing consists in application of drop of adhesive on surface of backing, in installation of pin at distance z from backing which is chosen from relation; Z=, where Z1 is specified thickness of layer of adhesive which should be produced after solidification; y is coefficient of shrinkage of adhesive (%). Force balancing weight of pin is applied to it for the course of time form moment of finish of installation of pin to finish of solidification of adhesive. Error of measurement of adhesion strength is ∓ 3%. EFFECT: increased precision of testing. 2 dwg
