ASTM C816-15 PDF

Scope: 5.1 Sulfur, even in very low concentrations, is of concern in a nuclear reactor because of potential corrosion of metallic components. This test method has the sensitivity to analyze very low sulfur contents in graphite using very small samples.

5.2 This test method can be used to characterize graphite for design purposes.

1.1 This test method covers the determination of sulfur in graphite in the concentration range from 18201;μg/g to 10008201;μg/g (ppm).

1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
