Description / Abstract:
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.
Purpose. This test procedure is used for the
qualitative and quantitative determination of Volatile Organic
Compound (VOC) and Semi-Volatile Organic Compound (SVOC) emissions
in vehicle interior air utilizing Tenax TA adsorbent media and
Thermal Desorption - Gas Chromatography/Mass Selective Detection
(TD-GC/MSD).
Individual VOC and SVOC emissions in different vehicle interior
air samples can be identified, quantified, and compared. 1.1.2 In
combination with GMW15634 the sources of VOCs and SVOCs in vehicle
air can be identified.
VOC emissions are in the boiling point range ≤ 345 °C or
chromatographic elution range from n-pentane (n-C5) to n-eicosane
(n-C20), and SVOC emissions are in the boiling range ≥ 280 °C or
chromatographic elution range from n-hexadecane (n-C16) to
n-dotriacontane (n-C32). This procedure can determine all of these
components in vehicle interior air.
Foreword. The determination of VOCs and SVOCs
in vehicle interior air is essential to meet customer and
regulatory requirements in global markets. Concentrations are in
the micrograms per cubic meter (μg/m3) range which warrants
accurate analytical measurements.
Note: There is no direct correlation between
the limits on material, component and vehicle level due to the high
complexity of chemical interactions, unpredictable influence of
different part sizes and addition, interaction and elimination of
their emissions.
Applicability. This test procedure can be used
for all air samples for the determination of VOC and SVOC emissions
including cabin air inside vehicles in a stationary or dynamic
mode. The results will provide complementary information to
interpret findings in GMW3205, GMW3059 and GMW15634. The test
procedure can be used to pursue customer complaints regarding odor.
The analytical instrumentation described herein is also applicable
for GMW15634 to determine the sources of VOCs and SVOCs in interior
materials.
This test procedure was modified from EPA TO-17.
This test procedure complements GMW15600.
