17、uction The test is conducted to determine the shear load resistance of the bond between the spray deposit and the parent material (adhesive strength) and/or the strength of the coating itself (cohesive strength). If adhesive strength of the sprayed coating to the base material supersedes the cohesiv
18、e strength, primarily the cohesive strength of the deposit is determined. During the test the coating is loaded parallel to the interface of coating/substrate. The test is used to evaluate the effects of parent material and spray material, surface preparation of the work piece before spraying, and t
19、he spraying conditions on the adhesive and/or cohesive strength of thermally sprayed coatings, or for quality control and routine supervision of the spray works.

20、EN 15340:2007 (E) 5 1 Scope This European Standard specifies the procedure for determination of the shear load resistance of thermally sprayed coatings, provided that a minimum thickness is given. Additionally this European Standard defines the shear load resistance and the designation of the fractu
21、res structure on the test specimen, which occurs when the shear adhesive or adhesive/ cohesive or cohesive strength of the coating or the coating system will be exceeded. The test report is the basis for comparative statements regarding shear load resistance and structure of fracture. NOTE The test
22、for the determination of the shear load resistance is not recommended for sprayed coatings thinner than approximately 150 m because the adjustment of shear distance becomes critical. 2 Normative references The following referenced documents are indispensable for the application of this document.
