This time, it’s the interior in the hottest of climates. (cleanmpg.com/forums/showthread.php?p=183607)

Patrik Libander - Clean Compartment Expert (sun simulation/material emissions) uses sun simulation to ensure low emissions in Volvo interiors.
All new models are verified as if they were parked in Mediterranean sun, to measure the interior emissions while at 150º Fahrenheit. In this temperature, interior materials would normally release harmful emissions. Volvo on the other hand is minimizing harmful emissions in the car interior, by using allergy-friendly textiles and carefully chosen materials.
There are no societal standards for in-car air, so Volvo has created its own in-car air quality requirements that are used when developing new models.
To fulfill Volvo requirements, all interior textiles are Oeko-Tex certified while other interior materials, components and systems have to pass strict tests both at the suppliers' and at Volvo’s Material Laboratory.
"Interior trim materials are not approved for use in our car interiors until they pass our strict tests", explains Patrik Libander, responsible for interior material tests at Volvo.
The Volvo standard has a low limit for TVOCs (Total Volatile Organic Compounds), as high levels in interior air would result in smell, cause headaches, nausea and dizziness, and could trigger asthma. Aldehydes are limited as they, especially formaldehyde, can cause both contact and respiratory allergies.
As emissions are released from the interior materials at high temperatures, Volvo’s material experts use a sunshine simulator at the Swedish Testing and Research Institute to verify low interior emissions in a new car model. The car is parked under the hot sun lamps, until the interior reaches temperature of 150º Fahrenheit - as it would after a day parked in sun.
Analyzing air samples, emissions of TVOCs (Total Volatile Organic Compounds) and aldehydes are verified to meet a maximum emission level. Volvo even has techs sit in the sun heated car compartment and evaluate the interior smell on a fixed scale.
Volvo has been conducting the sun simulation tests since 2000.
"Sun simulation test results are a major part of the test results reported to the Swedish Asthma and Allergy Association to get their approval and recommendation for the air in our car models. Altogether four Volvo models are recommended by the Swedish Asthma and Allergy Association, the S80, V70, XC70 and our latest newcomer, the XC60", concludes Patrik Libander.
