Popis

BS EN ISO 8988:2006


This standard BS EN ISO 8988:2006 Plastics. Phenolic resins. Determination of hexamethylene-tetramine content. Kjeldahl method, perchloric acid method and hydrochloric acid method is classified in these ICS categories:
  • 83.080.10 Thermosetting materials

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 are no other basic or acidic additives in the resin. If the resin contains additives which can be oxidized by perchloric acid, only the hydrochloric acid method (Clause 5) is applicable.
