Scope
This document specifies the test equipment, sample requirements, test procedures, and calculation of test results for the ash content, fixed carbon content, thermal weight loss, sulfur content, chlorine content, fluorine content, and radiation resistance tests of flexible graphite sheets.
This document is applicable to the determination of the ash content, fixed carbon content, thermal weight loss, sulfur content, chlorine content, and fluorine content of flexible graphite sheets, as well as the testing of their radiation resistance. The measurement range for sulfur content is 50μg/g to 10,000μg/g, the measurement range for chlorine content is 1μg/g to 500μg/g, and the measurement range for fluorine content is 1μg/g to 1,000μg/g.
