DIN ISO 12219-5:2012-09

This part of ISO 12219 describes a chamber based, static headspace type method for measuring volatile organic compounds (VOCs), formaldehyde and other carbonyl compounds which may diffuse from vehicle interior unit components into the cabin air. Static chamber intended to provide characteristic emission data of unit component to assembly level emission. It also specifies the emission test chamber, preparation of the test specimen, connection of the vapour sampling devices and test conditions. This method is intended for evaluating new car interior trim components but can, in principle, also be applied to used car components. The specified analytical procedure for VOCs is valid for the determination of volatile organic compounds (VOCs) ranging in concentration from submicrogram per cubic metre to several milligram per cubic metre. The method is applicable to the measurement of non-polar and slightly polar VOCs ranging in volatility from n-C6 to n-C16.
