Phenolic, amino and condensation resins - Determination of free-formaldehyde content (ISO 11402:2004)

ISO 11402:2004 specifies three methods for determining the free-formaldehyde content in the following:
Phenolic resins, by potentiometric titration in aqueous or organic solution (hydroxylamine hydrochloride procedure). The method is applicable to resins with free-formaldehyde contents up to and including 15 % by mass. For free-formaldehyde contents between 15 % by mass and 30 % by mass, it may be necessary to adjust the concentrations of the standard volumetric solutions used accordingly.Amino resins and furan resins (sulfite procedure). The method is applicable to resins resulting from the polycondensation of urea and melamine with formaldehyde and to furan resins resulting from the polycondensation of furfuryl alcohol with formaldehyde without further modification.Condensation resins (KCN procedure), including urea resins, furan resins, melamine resins and phenolic resins, as well as combinations and modifications of these resins.
The purpose of this International Standard is to establish recognized and useful determination procedures (for instance in order to check whether official regulations on the handling of hazardous workplace materials are observed).
The free-formaldehyde content determined in formaldehyde condensation resins using this International Standard represents the actual content at the time of the determination. The value bears no quantitative relationship to the free-formaldehyde content during or after processing.

Phenol-, Amin- und Kondensationsharze - Bestimmung des Gehalts an freiem Formaldehyd (ISO 11402:2004)

Résines phénoliques, aminiques et de condensation - Dosage du formaldéhyde libre (ISO 11402:2004)

L'ISO 11402:2004 prescrit trois méthodes de dosage du formaldéhyde libre dans les produits suivants.
Les résines phénoliques, par titrage potentiométrique en solution aqueuse ou organique (méthode au chlorhydrate d'hydroxylamine). Cette méthode est applicable aux résines dont la teneur en formaldéhyde libre est inférieure ou égale à 15 % en masse. Si la teneur en formaldéhyde libre est comprise entre 15 % en masse et 30 % en masse, il peut être nécessaire d'ajuster en conséquence les concentrations des solutions titrées utilisées.
Les aminorésines et les résines furanniques (méthode au sulfite de sodium). Cette méthode est applicable aux résines résultant de la polycondensation de l'urée et de la mélamine avec du formaldéhyde, et aux résines furanniques résultant de la polycondensation d'alcool furfurylique avec du formaldéhyde sans autre modification.
Les résines de condensation (méthode au cyanure de potassium), comprenant les résines d'urée, les résines furanniques, les résines de mélamine et les résines phénoliques, ainsi que les combinaisons et modifications de ces résines.
La présente Norme internationale a pour objet d'établir des modes opératoires de dosage reconnus et utiles (par exemple dans le but de vérifier si les règlements officiels concernant la manipulation des produits dangereux sur les lieux de travail sont observés). Dans la mesure du possible, toutes les résines contenant du formaldéhyde sont à inclure dans ce propos.
La quantité de formaldéhyde libre déterminée dans les résines de condensation du formaldéhyde en utilisant la présente Norme internationale représente la teneur réelle au moment de l'essai. La valeur n'a pas de relation quantitative avec le formaldéhyde libre qui pourrait apparaître pendant ou après la transformation.
