Scope

This part of ISO 12219 describes and specifies the whole vehicle test chamber, the vapour sampling
assembly and the operating conditions for the determination of volatile organic compounds (VOCs),
and carbonyl compounds in vehicle cabin air. There are three measurements performed: one (for VOCs
and carbonyl compounds) during the simulation of ambient conditions (ambient mode) at standard
conditions of 23-25 °C with no air exchange; a second only for the measurement of formaldehyde at
elevated temperatures (parking mode); and a third for VOCs and carbonyl compounds simulating
driving after the vehicle has been parked in the sun starting at elevated temperatures (driving mode).
For the simulation of the mean sun irradiation, a fixed irradiation in the whole vehicle test chamber is
employed.
The VOC method is valid for measurement of non-polar and slightly polar VOCs in a concentration range
of sub-micrograms per cubic metre up to several milligrams per cubic metre. Using the principles
described in this method, some semi-volatile organic compounds (SVOC) can also be analysed.
Compatible compounds are those which can be trapped and released from the Tenax TA®1) sorbent
tubes described in ISO 16000-6, which includes VOCs ranging in volatility from n-C6 to n-C16.
The sampling and analysis procedure for formaldehyde and other carbonyl compounds is performed
by collecting air on to cartridges coated with 2,4-dinitrophenylhydrazine (DNPH) and subsequent
analysis by high performance liquid chromatography (HPLC) with detection by ultraviolet absorption.
Formaldehyde and other carbonyl compounds can be determined in the approximate concentration
range 1 μg/m3 to 1 mg/m3.
