Plastics. Phenol-formaldehyde mouldings. Determination of free ammonia and ammonium compounds. Indophenol method Ingestion-build-103253 3 Determination of carbon dioxide1 Scope This International Standard specifies a colorimetric comparison method for the determination of the amount of ammonia and ammonium compounds in phenol formaldehyde mouldings. NOTE This International Standard does not provide an absolute measure of the amount of ammonia present. The amount of ammonia in a moulded article is of importance when corrosion of metal inserts or contamination of foodstuffs in contact with the article has to be
