ASTM E285: Standard Test Method for Oxyacetylene Ablation Testing of Thermal Insulation Materials
Abstract: This test method covers the screening of ablative materials to determine the relative thermal insulation effectiveness when tested as a flat panel in an environment of a steady flow of hot gas provided by an oxyacetylene burner.
This test method should be used to measure and describe the properties of materials, products, or assemblies in respo...

ASTM E471: Standard Test Method for Obtaining Char Density Profile of Ablative Materials by Machining and Weighing
Abstract: This test method covers the determination of the char density profile of a charred ablator that can be used with the following limitations:
The local surface imperfections must be removed, and the char must be able to be machined off in a plane parallel to the char-virgin material interface before the density profiles can be determined.

ASTM E458: Standard Test Method for Heat of Ablation
Abstract: This test method covers determination of the heat of ablation of materials subjected to thermal environments requiring the use of ablation as an energy dissipation process. Three concepts of the parameter are described and defined: cold wall, effective, and thermochemical heat of ablation.

Standard Test Method for Obtaining Char Density Profile of Ablative Materials by Machining and Weighing: E471 - 96(2016)
Abstract: This test method covers the determination of the char density profile of a charred ablator. The total thickness of the char and degradation zone must be larger than the machining thicknesses required. Density variation ...
