3.1 Task from 5th meeting: Comments on test temperature ambient mode 23° or 25°C

Dr. Lee on behalf of Korea gave a presentation on VIAQ measurement results at 23°C and 25°C. Measured values for VOCs and Aldehydes were very similar at both temperatures. Acetaldehyde and Formaldehyde were slightly higher at 25°C. The expert from Korea concluded that ambient test temperature can be set to 23°C or 25°C. Korea would prefer testing at 25°C, but won’t oppose 23°C (VIAQ-06-09).

Dr. Bulycheva on behalf of Russia said that 23°C test temperature is more relevant for Russia, but won’t oppose a compromise.

Prof. Ge on behalf of China suggested a compromise of testing temperature from 23,0-25,0°C.

Dr. Kovacs on behalf of OICA said that OICA is in favour of 23°C test temperature, but won’t oppose on a test temperature of 25°C. However, OICA temperature deviation at 25°C [then] has to be limited to +/- 0,5°C.

The group concluded on the compromise of China for an ambient test temperature from 23,0-25,0°C, recommended to be as close as possible to 25.0 °C, and closed this working item.
