适用范围：This International Standard specifies an iodometric method for the semi-quantitative determination of the amount of free phenols in phenol-formaldehyde mouldings. NOTE - This Internationa! 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 conta-mination of foodstuffs or other materials in contact with the article has to be considered.
