2 VIAQ – Dr.M.W.Pharaoh © 2006 IARC Deliverables - VIAQ Technical:  Characterisation of interior trim components with respect to consistent adherence to emerging interior air quality (VIAQ) limits.  Realistic solutions to address any departures from VIAQ requirements.  Recommended VIAQ test methodology and component performance specification.  Effective engagement with and dissemination of information to the supplier base.

3 VIAQ – Dr.M.W.Pharaoh © 2006 IARC Primary Objectives  Develop capability within the supply base to satisfy the requirements of potential vehicle interior air quality (VIAQ) legislation.  FOCUS - Emissions from the plastics and adhesives

4 VIAQ – Dr.M.W.Pharaoh © 2006 IARC VIAQ  What is it? - measure of quality of air within passenger cell resulting from emissions of Volatile Organic Compounds (VOCs) from interior trim components and materials used during vehicle manufacture  Why pursue it?  Increasing interest in the effect of VOC emissions from interior trim materials  voluntary code of conduct established in Japan  future legal requirements being considered

6 VIAQ – Dr.M.W.Pharaoh © 2006 IARC Work programme - Vehicle Interior Air Quality  Vehicle sampling being performed at Solihull, Castle Bromwich, Halewood and Gaydon.  In conjunction with key suppliers, develop realistic materials and process technologies to address any departures from the requirements.  Help develop a recommended test methodology and component performance specification for interior trim components.

7 VIAQ – Dr.M.W.Pharaoh © 2006 IARC Analysis process  Clean air drawn through media in absorbent tube, which traps organic volatiles. Different media are chosen depending composition and volatility.  Heated and VOC’s driven off into a GC/MS (gas chromatograph / mass spectrometer) which compares traces against standards for identification and concentration.

9 VIAQ – Dr.M.W.Pharaoh © 2006 IARC Detected Compounds  VVOCs (very volatile…). Low molecular weight compounds, e.g. acetone, methanol  VOCs (volatile organic compounds), benzene, toluene, styrene.  SVOCs (semi volatile….). High molecular weight. Oily liquids (often fogging compounds), e.g. phthalates.

10 VIAQ – Dr.M.W.Pharaoh © 2006 IARC Test configuration / sampling process Air flow rate / sampling time very closely controlled to give consistency of results. Results in micrograms per m 3 These must be below values given in regulations. Will effect: health toxicity, odour and fogging.

11 VIAQ – Dr.M.W.Pharaoh © 2006 IARC VIAQ Test Programme IARC emission lab set-up:

12 VIAQ – Dr.M.W.Pharaoh © 2006 IARC VIAQ Test Programme – Lab demo Air sampling facility now set-up in IARC laboratory  Equipment purchased and commissioned  New equipment (micro-chamber) allows the collection of air samples from small samples (~ ∅ 40mm) of material: Can heat samples for emissions testing E.g. interior trim samples, sections from mouldings

13 VIAQ – Dr.M.W.Pharaoh © 2006 IARC Standard Trace - BTEX / Phthalates

14 VIAQ – Dr.M.W.Pharaoh © 2006 IARC Typical Vehicle GC/MC Trace Complex trace showing many trace elements – from a wide variety of sources

15 VIAQ – Dr.M.W.Pharaoh © 2006 IARC Typical MDI foam – micro chamber Relatively simple trace showing strong response from low molecular weight compound
