Plastics — Phenol-formaldehyde mouldings — Determination of free ammonia and ammonium compounds — Indophenol method

Summary

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 considered.
