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 demineralized 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 derivatization with 2,4-dinitrophenylhydrazine (DNPH) 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 [μg/g] of the test piece.

Foreword. The determination of aldehydes and ketones in vehicle materials and components is essential to meet customer requirements and regulatory requirements in some global markets.

Applicability. This test procedure is applicable to all solid polymer materials and components used in vehicle interiors. The results will provide complementary information to GMW14444.
