Standard Test Method for Nitrogen Content of Soluble NitrocelluloseAlternative Method (Withdrawn 2017)

Scope

1.1 Test Methods D 301 for measuring nitrogen content in nitrocellulose by nitrometer are the accepted standard. However, the glassware is specialized and the precision is dependent on the development of a high level of skill by the operator. The ferrous-sulfate titration of nitrate is a classical procedure. By controlling critical variables and automating the actual titration, precision equivalent to the nitrometer can be achieved with nitrocellulose. This test method describes such a procedure.

1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

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. For specific hazard statements, see Section 8.

Significance and Use

This test method provides a simpler means for measuring the nitrogen content of nitrocellulose than the nitrometer described in Test Methods D 301. Under controlled conditions, the procedure described is capable of results equivalent to those obtained by the nitrometer.
