VDA 278 VOC & FOG Emissions Testing - Overview
VDA 278 is a standardised procedure for testing automotive interior materials for volatile organic compounds (VOC) and condensable emissions (FOG) that might be emitted by these materials. The test evaluates how non-metallic automotive interior materials react in terms of emitted compounds to ensure that they meet indoor air quality requirements.
This standardised procedure uses thermal desorption, followed by gas chromatography/mass spectrometry (TD-GC/MS), to detect organic emissions from materials at raised temperature levels. VOCs, however, are tested at lower temperature levels, similar to those found inside a car, while FOGs contain compounds that might condense on surfaces like windshields at raised temperature levels.
Scope, Applications, and Benefits
Scope
VDA 278 is a testing standard used to determine the amount of volatile matter that is released by automotive interior materials. It focuses on the chemicals that are released by these materials during heating, as controlled by thermal desorption. This is an important standard in the automotive industry, used to ensure that the air inside an automotive cabin is clean and that the materials used inside the automotive cabin meet high standards.
VDA 278 is used to detect the chemicals that are released by automotive interior materials. It is used to detect:
– Volatile Organic Compounds (VOC)
– Condensable Organic Compounds (FOG)
Applications
- Automotive interior material qualification
- Vehicle cabin air quality evaluation
- Material selection for interior components
- Supplier material validation
- Quality control of automotive parts
- Development of low-emission materials
- Research and development of automotive materials

- Ensures low-emission interior materials
- Improves vehicle cabin air quality
- Reduces windshield fogging risks
- Supports compliance with OEM emission requirements
- Detects volatile and semi-volatile compounds
- Standardised emission measurement method
- Enhances passenger comfort and safety
- Supports supplier material qualification
VDA 278 VOC & FOG Emissions Testing - Test Process
Sample Preparation
Automotive material specimens are cut to size and placed in thermal desorption tubes.
1VOC Measurement
The sample is heated to about 90°C to release volatile organic compounds for analysis.
2FOG Measurement
The sample is further heated to about 120°C to release condensable organic compounds (FOG).
3GC-MS Analysis & Interpretation
Released compounds are analyzed using GC-MS and VOC/FOG emission levels are calculated.

Frequently Asked Questions
VDA 278 is a standardized automotive test method used to measure volatile organic compounds (VOC) and condensable organic compounds (FOG) emitted from interior vehicle materials. It evaluates emissions that may affect cabin air quality and cause windshield fogging.
VOC refers to low-boiling volatile organic compounds that evaporate easily and contribute to cabin air contamination. FOG refers to higher boiling organic compounds that can condense on cooler surfaces such as windshields, potentially causing fogging.
The test is suitable for automotive interior materials such as plastics, rubbers, foams, textiles, adhesives, coatings, sealants, and interior trim components.
The test uses thermal desorption followed by gas chromatography–mass spectrometry (TD-GC/MS) to separate, identify, and quantify emitted organic compounds.
VOC emissions are typically measured at around 90°C, while FOG emissions are measured at a higher temperature of around 120°C.
