Abstract - (Show below) - (Hide below)

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.
