1.1These test methods cover the determination of mass fraction % of carbon, nitrogen and oxygen in silicon nitride powder having chemical compositions within the following limits:

Element	Mass Fraction % Range

Carbon	0.05 to 5.0
Nitrogen	30 to 45
Oxygen	0.1 to 1.5

1.2Two test methods appear in this standard.

1.2.1Total Carbon by the Direct Combustion-Infrared Measurement Method.

1.2.2Nitrogen by the Inert Gas Fusion-Thermal Conductivity Measurement Method and Oxygen by the Inert Gas Fusion-Infrared Measurement Method.

1.3This 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. Specific hazard statements are given in Section 6.
