Oxidation tests frequently carried out as means of obtaining basic information on the environmental resistance of engineering materials. An investigation was undertaken to evaluate the effects of various test parameters on the oxidation behavior of monolithic non-oxide ceramics, the result being used to formulate a European testing standard. This paper describes the results of tests using sintered SiC, hot pressed and sintered Si(3)N(4), Syalon 201 and RSBN in the temperature range 900 C to 1400 C. The oxidation standard will require the use of flexural strength test pieces (according to EN843-1) and that the assessment of oxidation damage will include a mass, dimension and flexural strength changes.
