Paints and varnishes - Determination of preservatives in water-dilutable coating materials - Part 1: Determination of in-can free formaldehyde (ISO 7012-1:2025)

The method describes the quantitative determination of the concentration of in-can free formaldehyde in water-dilutable coating materials. Note: The standard can also be applied for polymer dispersions. The determination method for in-can free formaldehyde can be only of limited suitability for pigmented systems, as the inherent coloration of the material may have an influence on the detection method.
