What is BS EN 828 - Adhesives about ?
BS EN 828 specifies a method for the determination of the surface free energy of a solid surface by measuring the contact angle of a liquid wetting the solid surface. It allows the prediction of the ability of a particular adhesive to wet a particular adherend. It can be used to characterize surfaces intended for pre-treatment, coating, or bonding. NOTE 1 In order to determine the surface free energy, the method of measuring the static contact angle is used in combination with a statistical interpretation. NOTE 2 The measurement results are influenced by mechanical surface roughness and chemical homogeneity.
