GSO ISO 120:2015 Scope
This International Standard specifies a colorimetric comparison method for the semi-quantitative determination of the amount of ammonia in phenol-formaldehyde mouldings.
NOTE — This International Standard does not provide an absolute measure of the 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.
