Principle 4
The sample was exposed to a particular test temperature under an atmosphere of carbon monoxide, after a certain amount of time to observe the extent of the damage the specimen.
Note. The toxic carbon monoxide gas, set the appropriate security measures, such as leakage detection equipment atmosphere surrounding the test to check for carbon monoxide.
5 device
5.1 Test Furnace
Figure 1 is a schematic diagram of the test equipment.
Of sufficient size to accommodate the test area of \u200b\u200bthe reaction chamber and within, 500 ℃, the temperature difference in the test area of \u200b\u200b± 10 ℃.
NOTE. When using the glass of the reaction chamber, the test furnace may consist of one or more of the viewing port, during the test in order to be able to directly observe the specimen.
