norganic Surface Coatings – Porosity Testing – Testing in a Humid Atmosphere Containing Sulfur. The porosity test in ISO 12687 aims to evaluate the porosity of metallic surface coatings by exposing them to a humid atmosphere containing sulfur. Porosity is a crucial indicator of a coating’s ability to resist corrosion, as porous areas can allow corrosive agents to reach the substrate. This test ensures the coating provides adequate protection even under harsh conditions.
