Determining the free formaldehyde in DE UZ 102
Posted Date:2025/6/17
Determining the free formaldehyde:
Two test methods are permitted:
a) according to the Guideline for the determination of the formaldehyde concentration in water- soluble paints and varnishes, and polymer dispersions (“VdL Guideline 03 on Formaldehyde Determination“),
b) the same as a), although the concentration of free formaldehyde in the product can be determined using high pressure liquid chromatography (HPLC) if the testing laboratory can establish the comparability with VdL Guideline 03.
The verification test must be performed twice (double determination).
