Plastics. Phenolic resins. Determination of hexamethylene-tetramine content. Kjeldahl method, perchloric acid method and hydrochloric acid method1 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.
