This International Standard specifies an iodometric method for the semi-quantitative determination of the amount of free phenols in phenol-formaldehyde mouldings. NOTE — This International Standard does not provide an absolute measure of the free phenols present. The amount of free phenols in a moulded article is influenced to a major extent by the degree of cure. Its evaluation is also of interest where the possibility of contamination of foodstuffs or other materials in contact with the article has to be considered.
