ASTM D6979-18 Basicity in Polyols, Expressed as Percent Nitrogen
The essential components in polyols that are soluble in glacial acetic acid and reactive with perchloric acid are measured using this ASTM D6979-18 test procedure. This approach has been used to assess samples containing 0.3 to 10% nitrogen. The values indicated in SI units are to be regarded as standard.
