EN ISO 11402 Phenolic, Amino and Condensation Resins - Determination of Free Formaldehyde Content

EN ISO 11402 specifies three methods for determining the free formaldehyde content in:

  • Phenolic resins (hydroxylamine hydrochloride procedure) by potentiometric titration in aqueous or organic solution. The method is applicable to resins with free formaldehyde content up to and including 15% by mass. For free formaldehyde contents between 15% by mass and 30% by mass, the concentrations of the standard volumetric solutions used may need to be adjusted accordingly;
  • Amino resins and furan resins (sulphite procedure). The method is applicable to resins resulting from polycondensation of urea and melamine with formaldehyde and to furan resins resulting from 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 identification procedures (for example, to check compliance with official regulations regarding the handling of hazardous workplace materials).

The free formaldehyde content determined in formaldehyde condensation resins using this international standard represents the actual content at the time of determination. The value is not quantitatively related to the free formaldehyde content during or after processing.
