Description of BS ISO 12219-10:2021 2022
This document describes and specifies the whole vehicle test
chamber, the vapour sampling assembly and the operating conditions
for the determination of volatile organic compounds (VOCs; for more
information see Annex E), 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 °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, 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
ISOÂ 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 1Â ?g/m3 to 1Â mg/m3.
This method applicable to trucks and buses, as defined in ISOÂ 3833:1977 3.1.1 to
3.1.6.
This document describes:
-
Transport and storage of the test vehicle until the start of
the test.
-
Conditioning of the surroundings of the test vehicle and the
test vehicle itself as well as the whole vehicle test
chamber.
-
Conditioning of the test vehicle prior to measurements.
-
Simulation of ambient air conditions (ambient mode).
-
Formaldehyde sampling at elevated temperatures (parking
mode).
-
Simulation of driving after the test vehicle has been parked
in the sun (driving mode).
