44、irements for Interior Space: The interior air testing is conducted in a new car with an age, which is representative for the time between manufacturing and sales, max. 4 weeks (28 days +/- 5). Because of the known VOC emission behaviour of materials these measurements lead to maximum concentrations
45、which decay with increasing time after the production date. The objective is to determine the indoor air concentration of volatile organic compounds under the typical conditions of use. The typical temperature in a car is assumed to be 21C. In order to maintain this temperature at higher outdoor tem
46、peratures an integrated air conditioning is recommended Before the measurement the car is conditioned in a climatic chamber at 21 2C for at least 8 h. A sampling tube is installed at the drivers nose position and all windows and doors are closed. During the interior air sampling a temperature of 21
47、2C is maintained. The sampling time is 30 minutes. The measurement takes place without any air exchange. By this procedure the mean VOC concentration is determined a passenger is exposed to in a closed car during the first 30 min after entering the car. According to practical observations after 30 m
48、in passengers would at least partly open the windows or switch on the fan in order to breathe fresh air and to reduce the carbon dioxide concentration in the interior air The conditioning and sampling temperatures against time are monitored by a data logger. The air in the test chamber outside the c
49、ar is measured simultaneously in order to determine the blank values of VOC components. A second measurement is done after driving the car for 30 min in order to detect volatile organic compounds which might be released by the warm motor and contaminate the interior air through leaks in gaskets and seals. In connection with both measurements the odour of the interior air is documented. Only a weak
