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 micrograms per gram (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 materials and components used in vehicle interiors that may contain carbonyls (e.g., polyoxymethylene, parts containing wood, natural or laminated fibers, leather, artificial leather, adhesives, sealants, polyurethane, cotton fleece, joint fabric fleece, phenol/formaldehyde resins, etc.) The results will provide complementary information to GMW14444.
