BS EN 828:2013

This standard BS EN 828:2013 Adhesives. Wettability. Determination by measurement of contact angle and surface free energy of solid surface is classified in these ICS categories:

• 83.180 Adhesives

This European Standard 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.
