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 semi-quantitative determination of emissions for interior materials via Headspace-Gas Chromatograph - Mass Spectrometry (GC-MS). With the emission spectra: · Emissions of interior materials can be compared · Resultant emissions can be identified · Relative emissions can be calculated · Substances with regard to GMW3059 can be identified

Foreword. The test defined in this standard is designed to evaluate the "emission" tendencies of all interior and air ventilation system materials. The resulting rating “Relative Emission” influenced by the volatile organic constituents, liberated under conditions of high ambient temperatures and subsequently stays in the interior air, is determined.

Applicability. All interior parts including HVAC ducts, trunk trim, and insulation having an air flow to the interior are included under this standard. For clarification refer to the responsible GM material engineer. All parts having an air flow to the interior with an area of > 50 cm² or a weight of > 10 g shall be tested.

For parts that are < 50 cm² or have a weight < 10 g, but that will be used several times in a vehicle the following rule applies: The area or the weight of the part has to be multiplied by the number of parts. If the resulting weight is > 10 g or the area is > 50 cm² the part shall be tested.

The results will provide complementary information to GMW15634 and GMW3205.
