Significance and Use | ||||||||||
These test methods are for the chemical analysis of mass fraction of carbon, nitrogen and oxygen in silicon nitride powder. It is assumed that all who use these test methods will be trained analysts, capable of performing common laboratory procedures skillfully and safely. It is expected that work will be performed in a properly equipped laboratory. |

1. Scope | ||||||||||
1.1 These test methods cover the determination of mass fraction % of carbon, nitrogen and oxygen in silicon nitride powder having chemical compositions within the following limits:
1.2 Two test methods appear in this standard. 1.2.1 Total Carbon by the Direct Combustion-Infrared Measurement Method. 1.2.2 Nitrogen and oxygen by the Inert Gas Fusion-Thermal Conductivity Measurement Method. 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. Specific hazard statements are given in Section 6. |
