Environmental Competence: VIAQ
by Geraint Williams,
International Automotive Research Centre, University of Warwick, UK

Background
VIAQ (vehicle interior air quality) is a measure and control of the air quality within a vehicle's passenger cell. VIAQ is strongly affected by contamination from VOC (volatile organic compound) emissions arising from interior trim components and materials used during vehicle manufacture.

VIAQ is a topic which is rapidly gaining increased attention – there is growing interest with regards to the potential toxological effects of VOCs following studies performed into so-called sick-building syndrome. More specifically, a voluntary code of conduct has been established by the Japanese Automotive Manufacturers Association (JAMA) that places limits on particular VOC materials for newly manufactured vehicles. One OEM is also following suit with a model classified as having an allergy-free interior according to the TUEV specification. There is an additional craftmanship issue in terms of vehicle cabin odour and customer satisfaction.

VIAQ Project Objective:

Develop the capability within the supply base to satisfy the VOC emission requirements for emergent VIAQ legislation

Deliverables:

• Characterisation of selected vehicles and interior trim materials/components to determine current level of adherence to emerging VIAQ limits
• Formulate realistic materials/manufacturing solutions to address any significant departures from VIAQ requirements
• Deliver a recommended VIAQ test methodology and component performance specification
• Dissemination of information to supplier base to enable VIAQ targets to be met

• Established necessary baseline competence
• Defined/implemented sampling and test methodologies for vehicles/components
• Procured state-of-the-art analytical equipment suite, commissioned on site at WMG
• Completed full-vehicle VIAQ evaluation of selected vehicle models
• Completed initial round of materials evaluation to validate test and analysis process
• Commenced engagement with component and materials suppliers
• Established template for data management
