This standard BS ISO 14849:1999 Plastics. Phenol-formaldehyde mouldings. Determination of free ammonia and ammonium compounds. Indophenol method is classified in these ICS categories:
  • 83.080.10 Thermosetting materials

This International Standard specifies a colorimetric comparison method for the determination of the amount of ammonia and ammonium compounds in phenol-formaldehyde mouldings.

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 considered.
