This International Standard specifies the method for high temperature corrosion testing of metallic materials by applying a deposit of salt, ash, and/or other substances and exposing them to high temperature in a controlled gas environment to evaluate their corrosion resistance. The deposit is applied prior to high temperature exposure by spraying, dipping, or painting.
This International Standard does not cover methods where test pieces are fully or partially embedded in corrosive substances or immersed in liquids. These methods are covered in ISO 17248 and ISO 17245, respectively.
