Plastics. Phenol-formaldehyde mouldings. Determination of free ammonia and ammonium compounds. Indophenol method Ingestion-build-107062 IEC 60364-4-41:19821 Scope This International Standard specifies a colorimetric comparison method for the determination of the amount of ammonia and ammonium compounds in phenol formaldehyde mouldings.
