ISO 15234 Paints and Varnishes - Standard Test for Testing Formaldehyde-Emitting Coatings and Melamine Foams

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of ISO 15234 testing. This International standard specifies a test method for determining the equilibrium concentration of formaldehyde from formaldehyde-emitting coatings and melamine foams in a small test chamber. Explains the determination of the equilibrium concentration of formaldehyde formed in the air at 23°C and 50% relative humidity.

The test closely simulates practical conditions and can be performed on a laboratory scale. A good correlation is obtained with the values ​​obtained on samples of the same material in a 40 m³ test chamber. The method, which is easy to perform, is therefore suitable for the preliminary determination of the limits to be observed.

The desiccator is installed in an air-conditioned room so that the air in the room can pass first through the desiccator and then into a water trap where formaldehyde (HCHO) is absorbed. The water in the water trap is changed at regular intervals and the formaldehyde concentration c is determined photometrically by the acetylacetone method or another suitable method. The test is continued until the measured value for c no longer changes. The equilibrium concentration in the air in the test chamber ceql is considered to have been reached.
