Introduction

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 (TDGC/ MSD).

Individual VOC and SVOC emissions in different vehicle interior air samples can be identified, quantified, and compared.

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.

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.

Remarks. 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.
