Standard Test Method for Disintegration of Refractories in an Atmosphere of Carbon Monoxide
Shows the comparative behavior of refractory products with accelerated exposure to nearly pure CO at 940°F. The sample performance is rated based on the ASTM visual criteria. Specimens shall be 9" x 2 1/2" or 3" square in cross section. Maximum capacity of the test furnace is 50 specimens.
This test method is used to determine the relative resistance of various refractories to disintegration caused by exposure to a CO atmosphere. The results obtained by this method can be used to select refractories that are resistant to CO disintegration.
This test method is suitable for research and development and for establishing CO disintegration criteria for specification acceptance.
The disintegration of test specimens is accelerated by providing a higher concentration of CO than anticipated in most service environments. The effects on the test specimens may be different than those found for refractories in actual service conditions.
1.1 This test method covers the comparative behavior of refractories under the disintegrating action of carbon monoxide (CO). The test method is an accelerated exposure to CO to determine potential material behavior in a relatively short time.
