This test method can also be applied to the analysis of additive concentrates and additive packages.

This test method may not be applicable to certain materials containing N–O or N–N junctions. However, samples used in the joint program were combined with existing ashless additives containing nitrogen to determine the precision of the test method. Complete recovery of nitrogen contained in these additives was achieved.
