GMW17082 1st Edition, January 1, 2014 Determination of Volatile and Semi-Volatile Organic Compounds from Vehicle Automotive Materials using a Micro-Scale Chamber
More info
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 standard is used for the qualitative and quantitative determination of Volatile Organic Compound (VOC) and Semi-Volatile Organic Compound (SVOC) emissions in automotive material (AM) utilizing the micro-scale chamber and a Thermal Desorber – Gas Chromatograph / Mass Selective Detector (TD-GC/MSD). Individual VOC and SVOC emissions in different vehicle materials can be identified, quantified, and compared. This method is an efficient and effective way to isolate emission sources and odors from automotive materials.
Individual VOC and SVOC emissions in different vehicle automotive materials can be identified, quantified, and compared.
VOC emissions in the boiling point range +345 °C or chromatographic elution range from n-pentane (n-C5) to n-eicosane (n-C20) (VOC value, GM) can be detected by one of the sorbent tube types specified in this method. It is assumed that these substances can be detected from vehicle interior air and total vehicle emissions.
Emissions that condense on a vehicle surface (e.g., glass, plastic lens, etc.) at ambient temperature are classified as SVOC or FOG emissions, as defined in glossary. SVOC emissions are in the boiling point range +280 °C or chromatographic elution range from n-hexadecane (n-C16) to n-dotriacontane (n-C32) (SVOC or FOG value, GM) and can be detected by this method.
Individual VOC and SVOC emissions identified as an odor can be quantified and compared.
Foreword. Determination of VOCs and SVOCs for Vehicle Interior Air Quality (VIAQ) is essential to meet customer and regulatory requirements in some global markets. VOCs and SVOCs found in interior air and total vehicle emissions originate from an automotive material source. Measurements are reported in parts per million (ppm) concentrations, which warrant accurate analytical results.
Applicability. All Automotive materials that can contribute to emissions in the vehicle interior air and total vehicle emissions can be tested. Examples include emissions from textiles, carpets, polymers, rubbers, elastomers, films, leather, and composite materials. Additional examples include cured adhesives, sealants, foams, primers, paints and coatings.
In relation to emissions, the relevant vehicle interior volume comprises all areas that are linked to the passenger compartment either directly or by air contact. Therefore, it includes the luggage compartment, the Heating, Ventilation, and Air Conditioning (HVAC) system, etc.
The results from this test procedure will provide additional information to interpret findings in GMW3059, GMW3205, GMW3235 and GMW15634.
Suppliers must submit the micro-scale chamber parameter conditions and Thermal Desorption - Gas Chromatography / Mass Spectrometry (TD-GC/MS) analysis results together with an automotive material sample.
This standard complements ISO 12219-3 and results may be compared to American Industrial Hygiene Association (AIHA) health standards.
