Purpose.
This test procedure describes a measuring process for determining the aldehyde and ketone emissions from vehicle interior materials.
For this test, test pieces are fastened above deionized water in a sealed bottle and stored in an oven for a specific period. Afterwards, the bottles are cooled, and the aldehydes and ketones absorbed in the demineralized water are determined.
The concentrations of aldehydes and ketones are determined by 2,4-dinitrophenylhydrazine (DNPH) derivatization followed by high performance liquid chromatography (HPLC) with ultraviolet (UV) detection.
The quantity of aldehydes and ketones are ascertained as a proportion of the dry weight in μg/g (micrograms per gram) of the test piece.
