BS EN 15340 is a European Standard that specifies the procedure for the determination of the shear load resistance of thermally sprayed coatings, provided that a minimum thickness is given.
Additionally, BS EN 15340 defines the shear load resistance and the designation of the fracture’s structure on the test specimen, which occurs when the shear adhesive or adhesive/ cohesive or cohesive strength of the coating or the coating system is exceeded.
The test report is the basis for comparative statements regarding shear load resistance and structure of fracture.
Note: The test for the determination of the shear load resistance is not recommended for sprayed coatings thinner than approximately 150 μm because the adjustment of shear distance becomes critical.
BS EN 15340 on shear load resistance of thermally sprayed coatings is useful for:
Users of gas control units for thermal spraying such as:
Contractors / project managers / authorities for:
Thermal spraying involves heating a substance and then spraying it onto a prepared substrate.
The test provided in BS EN 15340 helps you 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).
BS EN 15340 is useful to evaluate the effects of parent material and spray material, surface preparation of the work piece before spraying, and the spraying conditions on the adhesive and/or cohesive strength of thermally sprayed coatings, or for quality control and routine supervision of the spray works.
Compliance with BS EN 15340 on measurement of shear load resistance of thermally sprayed coatings helps you to improve the quality of the coating.
