American Society for Testing and Materials (ASTM). Current edition approved May 1, 2007. Published May 2007. Originally approved in 1959. Last previous edition approved in 2001 as B 78 – 90 (2001). 5 p. This test method covers the determination of the resistance to oxidation of iron-chromium-aluminum electrical heating alloys at elevated temperatures under intermittent heating using a constant-temperature cycle test. This test is used for internal comparative purposes only.
