Introduction

Volatile organic compounds (VOCs) are widely used in industry and can be emitted by many everyday

products and materials. They have attracted attention in recent years because of their impact on indoor

air quality. After homes and workplaces, people spend a lot of time in their vehicles. It is important to

determine the material emissions of interior parts and to reduce them to an acceptable level, if required.

Therefore it is necessary to obtain comprehensive and reliable information about the types of organic

compounds in the interior air of vehicles and also their concentrations.

This document outlines a method of measuring the types and levels of VOCs in vehicle cabin air under

controlled conditions. It describes requirements for a whole vehicle test chamber and a test protocol.

Measurements are carried out according to ISO 16000-6 (VOCs) and ISO 16000-3 (carbonyl compounds).

There are several national test methods available for measuring in-vehicle air quality, e.g. References

[2][4]. However, this document requires a fixed heating radiation system whereas the methods of

References [2][3] define a fixed temperature programme.

Before setting a fixed radiation density for heating the test vehicle, several validation measurements

were performed (Reference [1]).

[10] [11] [12]

ISO 16000-24, ISO 16000-25, as well as ISO 16017-1 and ISO 16017-2 also focus on volatile

organic compound (VOC) measurements.

FINAL DRAFT INTERNATIONAL STANDARD ISO/FDIS 12219-1:2021(E)
Interior air of road vehicles —
Part 1:
Whole vehicle test chamber — Specification and method
for the determination of volatile organic compounds in
cabin interiors
1 Scope

This document 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

specified in this method, some semi-volatile organic compounds (SVOC) can also be analysed.

®1)

Compatible compounds are those which can be trapped and released from the Tenax TA sorbent

tubes described in ISO 16000-6, which includes VOCs ranging in volatility from n-C to n-C .

6 16

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

3 3
range 1 µg/m to 1 mg/m .
The method is valid for passenger cars, as defined in ECE-TRANS-WP.29/1045.
This document give guidelines for:
a) transport and storage of the test vehicles until the start of the test;

b) conditioning for the surroundings of the test vehicle and the test vehicle itself as well as the whole

vehicle test chamber;
c) conditioning of the test vehicle prior to measurements;
d) simulation of ambient air conditions (ambient mode);
e) formaldehyde sampling at elevated temperatures (parking mode);

f) simulation of driving after the test vehicle has been parked in the sun (driving mode).

users of this document and does not constitute an endorsement by ISO of the product named. Equivalent products

may be used if they can be shown to lead to the same results.

4 Apparatus and materials
4.1 General

The whole vehicle test chamber is big enough to house the test vehicle completely. An air-conditioning

system is installed to allow standardized air conditions for a temperature of 23-25 °C and for a humidity

of 50 % RH ± 10 % RH. A solar radiator system is installed to heat the test vehicle cabin with a fixed

irradiation. The resulting temperature inside the cabin depends on the insulation and the window glass

material (the minimum requirements are specified in 6.1) (see also Figure 1).
4.2 Heating radiator

Infrared radiator, halogen radiator or other radiators (simulating sunlight) (wavelengths < 300 nm

shall be filtered out). The heating radiators used shall be powered to create a radiation density at the

reference measurement point in the middle of the roof surface of the test vehicle of 350 W/m to 450 W/

2 2 2
m (400 W/m ± 50 W/m ).

The heating area shall cover at least the area of the test vehicle cabin and an additional 0,5 m more to

each side of the lower part of the glazing (footprint) (see Figure 1). Position the heating radiators on the

roof with a shining angle of 90° to the heating area. There shall be no heating radiators shining from the

side. The heating area shall be calibrated in squares of 25 cm × 25 cm with a radiation density of 400 W/

2 2

m ± 50 W/m . The required radiation density shall be available directly after the lamps are switched

on (within a few minutes).
The irradiation shall be measured in accordance with ISO 9060.

Take care not to have too short a distance between radiator and surface in order to avoid hot spots.

4.3 Sampling trains
4.3.1 Sampling in the test vehicle

Four sampling trains are employed: two for the VOC measurements in parallel and two for the carbonyl

compound measurements in parallel in the test vehicle (to check the repeatability) (see ISO 16000-3

for carbonyl compounds and ISO 16000-6 or ISO 16017-1 for VOCs). There is one sampling line with a

manifold for the division of the sampling flow outside the test vehicle (see 4.3.3). It consists of the probe,

the sampling line (heated, if necessary), the sorbent tube for VOC or the DNPH cartridge for carbonyl

compound sampling respectively, the gas meters and the pumps (see 4.5).

Prior to sampling, the sampling system shall be checked under sampling load conditions for air

tightness. Do not skip this critical step because leaks have a high impact on the test results due to the

large backpressure of the tubes and cartidges. To check for leaks, plug the inlet to the sample system.

Then use a vacuum pump to bring the sampling system to 71 kPa vacuum, then close a valve between

the sample system and the pump. After 30 seconds, the sample system vacuum shall be greater than

68 kPa to proceed. Do not change the sample trains in any way after the leak check procedure is

performed. Other equivalent leak checks can be performed.
4.3.2 Sampling in the whole vehicle test chamber

Four sampling trains are used to determine the background concentration in the whole vehicle test

chamber. The sampling trains are identical to those of 4.3.1, apart from the sampling line, which is much

shorter and not heated.

All sampling trains shall have a maximum vacuum decay rate of 30 kPa for an average of 10 s. The

nozzle is plugged for the leak check. Other equivalent leak checks can be employed.

4.3.3 Sampling line

Tubing, between the sampling point (probe) inside the test vehicle, via the manifold outside the test

vehicle to the VOC sorbent tubes or DNPH cartridges respectively (see Figure 1).
The sampling line shall be constructed so as to be:
a) as short as possible (maximum 5 m) with an internal diameter of 4 mm or more;

b) of inert, non-emitting and non-absorbing/non-adsorbing material [e.g. stainless steel or

polytetrafluoroethylene (PTFE) or glass/quartz (deactivated)];
c) proven that there are no contaminations or sink effects in the sampling line;

d) with heating device, if necessary, to prevent condensation/deposition on the inner walls (best

practice: temperature controlled to about 20 °C above air temperature inside the test vehicle).

The tubing should be inserted between the door and the door frame or between the door frame and the

glazing and should be sufficiently non-compressible to ensure an unimpeded flow of air.

The second sampling line [tubing, between the sampling point (probe) in the whole vehicle test chamber

in the vicinity of the test vehicle [see 6.1 a)] and the manifold and to the VOC sorbent tubes or DNPH

cartridges, respectively] is identical to that described in the preceding, but no heating is necessary. This

second sampling line is needed to monitor the background analyte concentration of the whole vehicle

ISO/FDIS 12219-1:2021(E)

test chamber. This measurement is taken after the 24 h temperature acclimation phase and just prior to

opening the vehicle doors for the VOC conditioning phase.
4.4 Analytical equipment and materials

The analytical equipment used for the determination of VOCs and carbonyl compounds or formaldeyde

alone shall be in accordance with ISO 16000-6 (VOCs) or ISO 16000-3 (carbonyl compounds),

respectively.

It shall be proven for the VOC sorbent tubes and the DNPH cartridges that there is no breakthrough.

This can be identified by a back-up sorbent tube which is analysed separately (see ISO 16017-1).

4.5 Test vehicle

A new vehicle to be tested shall have been manufactured by the normal production process. The test

data are dependent on the trim level and exterior colour of the selected test vehicle. The colour of the

test vehicles for the determination of the official VOC and carbonyl compound emissions is black. If

there is no black test vehicle available, take the darkest colour.
All manual glazing shades shall remain open.

The test vehicle shall be stored and transported under conditions preventing direct solar heating,

otherwise the vehicle shall be conditioned after arrival overnight with open doors and windows before

it is transferred into the whole vehicle test chamber. No transport waxes for protection should be used.

All transport foils or transit lacquers shall be removed at least 24 h before the test.

To establish quality control, it is recommended to measure several vehicles and take multiple air

samples of one vehicle for one result. Therefore, it was decided because of cost reasons that measuring

one vehicle. However, general quality measures shall not be neglected and should be periodically

assessed.
5 Principle

A whole vehicle test chamber (see Annex A for an example) reserved for this purpose is assembled.

The air in the test vehicle cabin is measured according to a uniform standardized programme (see

Figure 1). Sampling of VOCs and carbonyl compounds is performed for the ambient mode at 23-25 °C, as

close as possible to 25 °C. Subsequently, formaldehyde is determined alone under elevated temperature

conditions in the parking mode (see Table 1). Sunshine is simulated by the use of heating radiators

providing a mean fixed irradiation for 4,5 h, after which a third sample is taken in the driving mode.

The humidity and temperature of the air inside the whole vehicle test chamber are measured. The

VOC and carbonyl compound vapour samples are taken in the driver breathing zone and collected on

VOC sorbent tubes and DNPH cartridges. Substances to be measured are: formaldehyde, acetaldehyde,

benzene, toluene, xylene, ethylbenzene, styrene, and acrolein.

Later the samples shall be analysed in the laboratory according to ISO 16000-6 or ISO 16000-3,

respectively.

Furthermore, VOC and carbonyl compound vapour samples are taken in the whole vehicle test chamber

to determine the background concentrations. The sampling trains are identical to those of 4.3, but

the sampling line is shorter and not heated. Altogether a minimum of 24 samples are required (see

Annex D).
The temperature resulting from use of the heat
