Corrosion of metals and alloys. Test method for high temperature corrosion testing of metallic materials by embedding in salt, ash, or other solids
This International Standard specifies the method for high temperature corrosion testing of metallic materials by embedding in a corrosive powder made up of salt, ash, and/or other solids and exposing them to high temperature in a controlled gas environment to evaluate their corrosion resistance.
Two options exist: fully embedding and partially embedding.
Fully embedding is used in cases in which a mass change measurement is required.
Partially embedding is used to investigate three potentially different interaction zones on a single test piece, i.e. the embedded part, the non-embedded part, and the gas/powder interface region. Therefore, gravimetric measurements are not appropriate and metallographic investigations are necessary instead.
This International Standard does not cover methods where test pieces are immersed in a liquid or cases in which a surface deposit is applied to the test pieces. These methods are covered in ISOÂ 17245 and ISOÂ 17224, respectively.
