Plastics. Phenolic resins. Determination of hexamethylene-tetramine content. Kjeldahl method, perchloric acid method and hydrochloric acid method Ingestion-build-98192 Metadata is descriptive data about1 Scope This International Standard specifies three methods for the determination of the hexamethylenetetramine (hexa) content of phenolic resins. The three methods are equivalent. The Kjeldahl method described in Clause 3 is not applicable if there are other components containing nitrogen in the phenolic resin. The perchloric acid method and the hydrochloric acid method described in Clause 4 and Clause 5, respectively, are only applicable if there
