scope:

1.1 This test method covers the determination of total nitrogen in nitrogen-containing organic compounds. This test method is not applicable for use on materials containing N-O, N-N linkages.

1.2 The values stated in SI units are to be regarded as 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.

Note 1-Another method of restricted application is given in Test Method D 1013.
