1 Scope
This test method describes a measuring process for determining the release of formaldehyde from
moulded parts for the vehicle interior. The test method was elaborated with reference to VDA 275
2 Principle
For this test, test pieces of a particular mass and dimension are fastened above demineralized water
a sealed 1- polyethylene bottle and stored at a constant temperature for a specified length of time
Aftewas the boles are cooed and the formaldehyde absorbed in the demineralized water is
determined. The quantity of formaldehyde is ascertained in relation to the dry weight(/)of the test
The formaldehyde is determined by photometric analysis using the acetylacet
ethod. In
aqueous solution, formaldehyde reacts with acetylacetone in the presence of ammonium ions to
become 3. 5-iacet l-1 4-di lutidine DD The resul in colour complex is yellow with maximum
absorption at a wavelength of 412 nm
