Automotive VOC Testing for Interior Components & Materials
The demand for testing procedures like VDA 278 and analyses of Volatile Organic Compounds (VOCs) and fog emissions are currently rising in the automobile sector. VDA 278 is a generally acknowledged standard for VOC testing among different industries, despite being most frequently used to assess emissions in the automotive industry.

Overview
Automotive VOC testing is a standardized procedure for evaluating the release of volatile organic compounds from materials used in the interiors of vehicles. These volatile compounds are typically derived from polymers, adhesives, coatings, and other materials used in the interiors of vehicles.
The test is of utmost significance in validating whether the materials comply with automotive OEM standards like VDA 278, ISO 12219, and other global automotive standards. The test is conducted to validate the release of volatile compounds, including TVOC, and their fogging tendencies at different temperatures. The test results ensure a safe and low-VOC-emitting vehicle interior.
Scope, Applications, and Benefits
Scope
Automotive VOC testing refers to a wide range of materials inside a vehicle to measure the emission of volatile compounds that affect air quality, passenger comfort, and regulatory compliance. It includes plastics, textiles, foams, coatings, adhesives, sealants, rubbers, as well as trim parts and dashboard materials. Testing is conducted under controlled temperature conditions that replicate real-world vehicle interiors, making it a valid way to study the evolution of VOCs over time.
Automotive VOC testing includes:
– Interior materials such as plastics, textiles, foams, coatings, adhesives, sealants, and rubbers
– Trim parts and dashboard materials
Applications
- Automotive interior material qualification
- OEM compliance testing
- Cabin air quality assessment
- Odour and fogging evaluation
- Supplier material approval
- Research and development of low-emission materials
- Polymer and coating formulation studies
Benefits
- Ensures improved in-cabin air quality
- Reduces health risks from harmful emissions
- Detects harmful volatile compounds
- Improves passenger comfort and safety
- Enhances product acceptance and brand value
- Provides standardised emission evaluation
- Supports sustainable material development
Test Process
Sample Preparation & Conditioning
Test specimens are cut to size and conditioned under controlled temperature and humidity.
1Thermal Desorption & VOC Collection
Samples are heated to release VOCs, which are captured using sorbent tubes or by condensation (fogging method).
2GC-MS Analysis
Collected compounds are separated by gas chromatography and identified/quantified using mass spectrometry.
3Data Evaluation
VOC emission levels are calculated and compared with applicable standards and limits.

Frequently Asked Questions
It helps prevent exposure to harmful chemicals, reduces unpleasant odours, ensures passenger comfort, and meets regulatory and manufacturer requirements.
Materials such as plastics, foams, textiles, adhesives, coatings, rubbers, and interior trim components are commonly tested.
TVOC (Total Volatile Organic Compounds) represents the total concentration of volatile compounds emitted, while SVOC (Semi-Volatile Organic Compounds) refers to compounds with lower volatility that may condense on surfaces.
Fogging refers to the condensation of volatile compounds on cooler surfaces, such as windshields, which can affect visibility and is evaluated separately.
Results are usually reported in µg/g (micrograms per gram), µg/m³ (micrograms per cubic meter), or mg/kg.
