Why in China, Korea, Japan etc. • Wikipedia - in part – “Alcohol flush reaction” • Asian ancestry, alcohol flush reaction has also been referred to by such informal names as Asian flush syndrome, Asian flush, and Asian glow. • The reaction is the result of an accumulation of acetaldehyde, a metabolic byproduct of the catabolic metabolism of alcohol, and is caused by an acetaldehyde dehydrogenase deficiency.
• Metabolism of alcohol (ethanol) to acetaldehyde (ethanal) and then acetic acid (ethanoic acid) • Genetics - “the flush reaction is rare among Europeans and Africans, and it is very rare among Mexican-Americans. 30% to 50% of people of Chinese and Japanese ancestry” • Bottom-line odor and VOCs are a quality issue for vehicle interiors in the China market.

National methods and ISO 12219-1 are conducted in generally the same manner. Harmonization to the ISO method would benefit both OEMs and suppliers by lowering the cost of testing and simplifying limit values.

The chart and tables shows the percent difference between either the national (Regulatory) limits and the national test methods. Note, for Formaldehyde the test method differences are nearly equivalent (100%) despite great difference in soak time, 2h vs.16h. But the limit values are not the same.
Vehicle Method and Time Study
Vehicle Method and Time Study • Two new vehicles were tested under different but typical conditions – Focus SE, windows open between tests = “daily use” – Focus ST, windows closed between tests = “dealership lot” – From day 4 to day 60 – Korean, ISO, TUV and China Methods – Test method windows closed soak times • Korean = 2 hours • ISO Part 1 = 8 hours • China = 16 hours • Next slides are VOC concentration [µg/m3] plots for each compound or group of compounds – Each plot is normalized to the highest test value – Note: TVOC is not regulated and drops quickly over time with windows open but this not true for Formaldehyde and Acetaldehyde. Also keep in mind, China limits for Formaldehyde and Acetaldehyde are difficult to meet.

VIAQ Test Method Conclusions • The full ISO test method, all three parts, should be discussed and adopted by the GRPE working group to achieve global harmonization. – Any modifications, if necessary, should be presented to ISO TC 146/SC 6/TC22 Joint WG 13 as improvements. – The next ISO JWG 13 meeting will be held from 26 to 30 September 2016 in Burlington, Vermont (United States). • Vehicle material emissions can be characterized using the ISO ambient mode – Data shows good correlation between the regional methods and the ISO method’s ambient mode. – The main issue of harmonize is the ambient mode soak time: 2, 8 or 16 hours. • Consider laboratory operations including an 8 hour operation with limited test site capacity. • Consider sampling when the emission rate is more stable. • Compound limit values should reflect method changes. – Improve to test repeatability • Increase mass on the sample; a function of soak length, sample flow rate, soak temperature • Include more quality control checks like duplicate samples and include void criteria. – Standardize test reports with defined data fields and data format
