What is ISO 24449 about?
ISO 24449 specifies a method for determining the thermal conductivity of ceramic top coat (TC) constituting thermal barrier coating (TBC) subjected to heat treatment, in a direction normal to the coating surface, from room temperature up to 1 000 °C.
ISO 24449 outlines the principles, terms and definitions, apparatus for measuring thermal diffusivity, specimen, measuring procedure, thermal conductivity of RC and the report.
