Specifies a method of revealing discontinuities and porosity in metallic coatings, where they penetrate the coating layer down to a substrate. Especially useful for coatings consisting of single or combined layers.
Abstract
Overview
EN ISO 12687:1998, titled , is a European adoption of the international standard. Developed and published by CEN, this standard specifies a such as gold, nickel, tin, palladium, and their alloys, especially when applied over silver, copper, or copper-alloy substrates. The method is designed to evaluate whether metallic coatings meet specific porosity acceptance levels critical to their performance.
