ASTM D 6991 - 05 Standard Test Method for Measurements of Internal Stresses in Organic Coatings by Cantilever (Beam) Method

American Society for Testing and Materials (ASTM). Current edition approved Feb. 1, 2005. Published February 2005. 5 p. This test method covers the procedure for measurements of internal stresses in organic coatings by using the cantilever (beam) method.
This method is appropriate for the coatings for which the modulus of elasticity of substrate (Es) is significantly greater than the modulus of elasticity of coating (Ec) and for which the thickness of substrate is significantly greater than thickness of coating.
