WebOxidation in air at 973 K for 5 min also increased the emissivity of SS 316 L. Oxidations for 10 and 15 min provided an additional increase, but it was not as significant. Analysis indicates that spallation of oxide layer occurred between 10 and 15 min oxidation. This is consistent with studies on the time variation of total normal emissivity ... WebStandard ASTM C835-06 was used to measure the total hemispherical emissivity of structural materials of RPV. The bell jar emissivity was measured using 304 stainless steel strips coated with black paint (Aremco HiE-Coat 840 M). Testing these strips verified that the internal bell jar emissivity is greater than 0.8 as required by the ASTM standard.
