Note: Nothing in this standard supercedes
applicable laws and regulations.
Note: In the event of conflict between the
English and domestic language, the English language shall take
precedence. 1.1
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 (g/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.
