ISO International Standard

ISO/TR 26946:2011 describes a method for characterizing the porosity of thermally sprayed coatings by metallographical examination.

This method is particularly applicable to oxide coatings, such as Al₂O₃, ZrO₂ and TiO₂, produced by plasma spray. It also considers the purposes to test the size, shape and density of pores for thermally sprayed coatings.
