From page 57...
... Notable examples of this approach are found in the several types of high-temperature tests developed by engine manufacturers to simulate the corrosive behavior found in specific engines operating under specific conditions. Burner rigs of various designs have evolved at each manufacturer that, through experience, can generate data for corrosion and thermal-shock resistance.

... High-temperature coatings have not been the specific subject of standards development, and many of the standards developed for other applications have been used where appropriate. The status of standard testing and analysis procedures varies with the specific aspect of coating technology considered and is summarized in the following section.

... Data usually consist of weight changes with time, corrosive penetration determination by me/allographic examination, phase-change identification, and corrosive product formation. 59 Dynamic testin, is usually conducted in burner rigs operating at atmospheric pressure and gas velocities of less than 100 feet per second.

... The ease of the laser flash technique makes it attractive for commercial use and argues for the development of a standard reference material that can be related to results from the guarded hot plate method. Heat transfer through coatings is influenced by the thermal emissivity as well as the thermal conductivity of the coating.
