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 considered.
