MUTUAL RESOLUTION No. 3 (M.R.3) OF
THE 1958 AND THE 1998 AGREEMENTS
CONCERNING VEHICLE INTERIOR AIR QUALITY (VIAQ)
The text reproduced below was adopted on November 14, 2017 by the World Forum for Harmonization
of Vehicle Regulations (WP.29) regarding the Agreement Concerning the Adoption of Uniform Technical
Prescriptions for Wheeled Vehicles, Equipment and Parts which can be fitted and/or be used on
Wheeled Vehicles and the Conditions for Reciprocal Recognition of Approvals Granted on the Basis of
these Prescriptions (1958 Agreement) and on November 15, 2017 by the Executive Committee AC.3 of
the Agreement Concerning the Establishing of Global Technical Regulations for Wheeled Vehicles,
Equipment and Parts which can be fitted and/or be used on Wheeled Vehicles (1998 Agreement)
(ECE/TRANS/WP.29/1118, Paras. 99-100 and 101). It is based on document ECE/TRANS/WP.29/2017/136.

I. STATEMENT OF TECHNICAL RATIONALE AND JUSTIFICATION
A. INTRODUCTION
1. A variety of materials are being used for the construction of the interiors of vehicles.
The materials used in the manufacturing of the vehicle include plastics, adhesives,
cleaning products, plasticizers, paint, sealers, lubrication compounds, and many
others.
2. Various kinds of chemical substances may be emitted from the interior materials
inside the vehicle cabin. Some of the chemical substances may contain components,
such as Volatile Organic Compounds (VOCs) including carbonyls like the aldehydes,
some of them are not harmful to the human body, but some of them are known to
cause various health issues. The amount of chemical substances emitted from
interior materials may be particularly high, especially during the early stages of
vehicle life.
3. Health effects vary depending on the individual driver and passenger's health and
physical condition as well as exposure time and concentration of chemical
substances. This Mutual Resolution supports the effort to insure that levels of these
chemical substances are measured under real exposure conditions.
4. Many countries throughout the world have already introduced standards concerning
vehicle interior air quality. Several countries have established regulations or
guidelines regarding emissions from interior materials. Although these test
procedures are very similar, there are many differences in test conditions.
5. This Mutual Resolution outlines the provisions and harmonized test procedure for the
measurement of interior emissions, taking into account existing standards. It will
encourage the reduced use of materials, and chemicals that can be harmful to
humans. It also encourages the increased use of emission-friendly materials,
improving the air quality inside the passenger cabin.
6. Experts also have an interest in global harmonization since it offers more efficient
development, adaptation to technical progress, and potential collaboration. It also
facilitates the exchange of information between interested parties.
7. The regulatory stringency of legislation is expected to be different from region to
region for the foreseeable future, due to the different levels of development, different
regional cultures, and the costs associated with interior emission control technology.
Therefore, the setting of interior emission limit values is not part of this
recommendation.

HJ/T 400-07 December 2007 "Determination of Volatile Organic Compounds
and Carbonyl Com-pounds in Cabins of Vehicles".
GB/T 27630-2011 March 1, 2012 "Guideline for air quality assessment of
Passenger car".
In China's standard, the Ministry of Environmental Protection and State
Administration of Quality Supervision, Inspection and Quarantine, prescribed
different concentration limits for eight VOCs, and is currently under revision to
become a mandatory national standard.
(c)
Russian Federation
GOST R 51206 "Interior air of road vehicles–Pollution content in the interior of
driver cab and passenger compartment Technical requirements and test
methods".
In the Russian Federation, test methods and regulations have focused on VOC
emissions from vehicle exhaust gases that can enter the vehicle interior air
during driving. The national standard GOST R 51206 was developed in 2004 to
set limits for combustion gases and certain VOCs.
The expert from the Russian Federation stated that the work should not only
focus on the interior air emissions generated from interior materials but also on
the air pollutants entering the vehicle together with the intake air from outside.
GRPE considered the inclusion in the scope of interior air pollutants from the
outside air as a possible extension of the mandate at a later stage
(ECE/TRANS/WP.29/GRPE/71).
(d)
ISO Standards
ISO 12219_1:2011 "Interior air of road vehicles – Part 1: Whole vehicle test
chamber – Specification and method for the determination of volatile organic
compounds in cabin interiors".
The ISO Group TC22/TC146 SC6 JWG13 harmonized the vehicle interior air
test method based on existing Korean, German Association of the Automotive
Industry (VDA) and JAMA testing methods. The ISO 12219-1 testing method is
adjusted VOC exposure in common user conditions: when sitting in a vehicle,
ambient mode, when entering the vehicle after parking in the sun, parking
mode and during driving, driving mode.
The JAMA voluntary standard was adopted to ISO 12219-1 Standard in 2013.

4. Test Mode
22. In order to get reproducible and comparable results it was decided to create a test
method, which is done in a highly defined environment. This can only be achieved
inside a laboratory. Thus, real driving test in varying outside conditions is not
possible. Typical laboratory methods used today to measure interior air quality are
Ambient, Parking and Driving modes.
5. Ambient Mode
23. Ambient mode simulates vehicles parked in the garage overnight using ambient
conditions at standard ambient conditions of 21°C to 27°C with no air exchange.
There were different opinions on test temperature for ambient mode. The expert of
Korea presented the test results between 23°C and 25°C, which were no significant
deviation between these temperatures. Test temperature of the ambient mode was
set up "23.0°C -25.0°C as close as possible to 25.0°C" taking into account the
technical point.
24. It was shown that a soak time of 16 ± 1h is sufficient to bring all vehicle parts to the
temperature of the ambient mode. Shorter soak times would give deviation in
measurement results, long soak times would lead to longer working hours and less
test capacity in the laboratory and therefore higher costs.
6. Parking Mode
25. Parking mode simulates vehicles parked outside in the sunlight at elevated
temperatures using a fixed radiation heat.
26. Heating the vehicle to a constant temperature would not consider the difference
between good and bad insulated vehicles. Therefore applying a constant solar load
better represents a real parking situation. It was analysed that a solar load of
400 ± 50W/m reflects best a worldwide average. A soak time of 4h has been shown
to be sufficient to reach a constant interior air temperature. The emissions of
Formaldehyde are measured in parking mode as a marker for emissions at elevated
temperatures.
7. Driving mode
27. Driving mode simulates driving under a parked idling condition after the vehicle has
been parked in the sun. The mode starts at an elevated temperature with climate
control system on. The concentrations measured in the driving mode are close to the
concentration customers are facing when driving in a vehicle. Of all test modes these
concentration are best suited to be taken for toxicological exposure evaluation.
8. Substances to be Measured
28. There are multiple substances emitted from the new vehicle interior materials. The
most relevant substances based on the groups knowledge and the current standards
were considered Formaldehyde, Acetaldehyde, Benzene, Toluene, Xylene,
Ethylbenzene, Styrene, and Acrolein.

E. TECHNICAL FEASIBILITY, ANTICIPATED COSTS AND BENEFITS
35. This Mutual Resolution has been developed by drawing on the experience of many
stakeholders, including regulatory authorities, vehicle manufacturers and technical
consultants. This Mutual Resolution has been designed to update and improve upon
existing standards. The requirements are based on existing concepts in different
contracting parties' present standards.
36. Since this Mutual Resolution is based on existing standards, Contracting Parties are
invited to adopt the test procedure for the measurement of interior emissions.
Ambient mode, parking mode, and driving mode would be subject to optional
acceptance by Contracting Parties depending on their situations. Therefore, no
economic or technical feasibility study was deemed necessary. When transposing this
VIAQ recommendation into national standards, Contracting Parties are invited to
consider the economic feasibility of the VIAQ recommendation within the context of
their own country.
37. This Mutual Resolution does not hold regulatory status within Contracting Parties.
Contracting Parties and manufactures refer to the VIAQ recommendation when used
for the assessment on vehicle interior air quality with the technical prescriptions of
their own standards or regulations.
38. The principal economic benefit of the VIAQ recommendation will be a reduction in the
variety of tests for the same, or substantially similar, test requirements.
39. Depending on how different Contracting Parties implement this Mutual Resolution,
there may be benefits to facilitate the trade of VIAQ management, with harmonized
test requirements among the respective Contracting Parties. Encouraging the use of
environmentally-friendly materials for the vehicle industry might be rationalized with
the harmonized test requirements.
40. Safety benefits resulting from this Mutual Resolution depend on the permissible
substance limit level in the national standards.
41. It is not possible to assess, at this moment, the total costs linked to this Mutual
Resolution. However, the harmonization of the test procedure will reduce the global
cost of VIAQ management in the countries which will apply the VIAQ
recommendation through an administrative procedure.
42. Safety benefits are anticipated, but it is not yet possible to assess them in terms of
the overall effect on human health.

3.6. "Parking mode" refer to the mode in which sampling of substances in the interior air of
a test vehicle under elevated temperatures resulting from defined external heat
radiation is performed;
3.7. "Driving mode" refer to the mode in which sampling of substances in the interior air of
a test vehicle, under standardized conditions starting at elevated temperatures and with
the engine on using air conditioning. Driving is simulated with an idle test procedure of
a vehicle driven after being parked in the sun;
3.8. "Breathing zone" the semi-sphere area with 50cm radius in front of the driver's face;
3.9. "Sampling train" means the apparatus to collect the air sample inside the test vehicle
cabin from the breathing zone and to collect the air sample from in the whole vehicle
test chamber, trapping the test substances in sorbent tubes under standardized
conditions;
3.10. "Category 1 vehicle" means a power driven vehicle with four or more wheels
designed and constructed primarily for the carriage of (a) person(s);
3.11. "Category 1-1 vehicle" means a Category 1 vehicle comprising not more than eight
seating positions in addition to the driver's seating position. A Category 1-1 vehicle
cannot have standing passengers.

7. REQUIREMENTS FOR THE TEST VEHICLE
7.1. Test vehicles should only be new vehicles from serial production. Used vehicles are not
included. The selection of vehicles should be based on a worst case interior to
minimize testing cost. Vehicles with dark exterior and preferably black or dark interior
colour are recommended for elevated temperature modes. Furthermore grouping
vehicles in families with similar interior emissions is also recommended. This approach
can be based on summing up vehicles with the same interior line and similar interior
volume.
7.2. The new vehicle, one not driven more than 80km and within 28d ± 5d after the sign-off
date in the production line to be tested shall have been manufactured by the normal
production process.
7.3. Transportation conditions from the assembly plant to the storing place and to the test
facility
7.3.1. Transportation of the vehicle should follow the normal transportation process.
7.3.2. All windows and doors should remain closed. HVAC outlets should remain closed to
avoid contamination.
7.3.3. Ensure that no external off-gassing materials will be transported in the same cargo
area. Minimize high solar load during all transportations. Documentation of all
deviations from the normal transportation process in the test protocol shall be reported
in the comments.
7.3.4. Influence of the driver shall be as low as possible. The vehicle driver and handlers shall
avoid the following: no smoking, eating, transportation of external items, and no
perfume, inside or near the test vehicle.
7.3.5. Protection covers used shall be the protection that will be used normally for
transportation of the remaining production vehicles. Absorbers are only allowed if used
in the normal transportation process.
7.4. Storing Conditions for the Vehicle
7.4.1. All windows, doors, and HVAC outlets keep closed to avoid from contamination and
avoid direct sunlight.
7.4.2. Do not use any cleaning agent to remove any residues. Dust wiping, vacuuming, and
cleaning with clear water is possible. Clear water cleaning form outside is possible.
7.4.3. No extra fuelling, only the first fuel at production shall be within the fuelling system.
7.4.4. Workers should carefully deal with the vehicle to prevent contamination.
7.4.5. Remove all protecting covers, foils, papers, stickers, absorbers, etc. at least 24h before
measurement.
7.5. Storing Conditions for the Vehicle 24h before Measurement
7.5.1. Storage shall be for 24h, of soak time before measurement nearby the test facility.
Control the soak storage temperature as close as possible to room temperature
between 20-30°C.

8.3. Sampling Trains
8.3.1. Requirements for VOCs and carbonyl compounds sampling and measurement of the
air in the cabin of the test vehicle and in the whole vehicle test chamber.
8.3.2. Sampling from inside the test vehicle shall have four sampling trains or a single sample
inlet but split into four parallel sampling trains. Two for the VOC measurements in
parallel and two for the carbonyl compound measurements in parallel in the test
vehicle. The second method sample is an analytical backup only. One sampling line
with a manifold for the division of the sampling flow outside the test vehicle is allowed.
The sample train consists of the sampling line, heated if necessary, the sorbent tube
and the DNPH cartridge for carbonyl compounds, the gas meters and the pumps.
8.3.3. Sampling in the whole vehicle test chamber. Four sampling trains are used to
determine the background concentration of VOCs and carbonyl compounds in the
whole vehicle test chamber. The sampling trains are identical to those of
Paragraph 8.3.2., apart from the sampling line, which is much shorter and not heated.
8.3.4. Prior to sampling, the sampling system shall be checked under the 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 cartridges. To
check for leaks plug the inlet to the sample system. Then use a vacuum pump to bring
the sampling system to 21in of Hg vacuum then close a valve between the sample
system and the pump. After 30s, the sample system vacuum must be greater than 20in
of Hg to proceed. If not, find and fix leak and repeat to proceed. Do not change the
sample trains in any way after the leak check procedure is performed. Other equivalent
leak checks can be employed.
8.3.5. Sampling lines are the tubing between the sampling points inside the test vehicle or via
the manifold outside the test vehicle to the VOC sorbent tubes or DNPH cartridges
respectively, see Annex I.
8.3.6. The sampling line shall be constructed as follows:
(a)
(b)
(c)
(d)
As short as possible (maximum 5 m) with an internal diameter of 4mm or more;
Of inert, non-emitting and non-absorbing/non-adsorbing material, e.g. stainless
steel or polytetrafluoroethylene (PTFE) or glass;
Proven that there are no contaminations or sink effects in the sampling line;
With heating device, if necessary, to prevent condensation or deposition on the
inner walls. Best practice is to control temperature to about 20°C above air
temperature inside the test vehicle.
8.3.7. 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.
8.3.8. The chamber sampling line in the whole vehicle test chamber is placed near the test
vehicle and goes to sorbent tubes or DNPH cartridges in parallel. The chamber
sampling line is identical to that described in the preceding vehicle sample line but no
heating is necessary. This second sampling line is needed to monitor the background
concentration of the whole vehicle test chamber. This measurement is taken after the
24h temperature acclimation phase and just prior to opening the vehicle doors for the
VOC conditioning phase.

9.2. Preparation and preconditioning of the whole vehicle test chamber, the vehicle, sample
trains, and the field blanks.
9.2.1. Preparation
(a)
(b)
(c)
Connect the test apparatus with the test vehicle. Attach the cables and sampling
lines to the door frame so that, when the doors are closed, there is a nearly
airtight sealing. Furthermore, the sampling line for VOCs and carbonyl
compounds sampling shall be installed in the test vehicle. The sample is
positioned as specified in Annex I;
Connect the sampling line with the manifold and the manifold with the sampling
trains for VOCs and carbonyl compounds measurements outside the test
vehicle;
Connect the test apparatus within the whole vehicle test chamber;
(d) Install the heating radiators and the other installations listed in 6.1.
9.2.2. Preconditioning of the Whole Vehicle Test Chamber
9.2.2.1. Adjust the temperature of the whole vehicle test chamber to 23.0-25.0°C, as close as
possible to 25.0°C during the ambient mode test. There may be the need for a heating
or cooling device. The humidity should be 50% RH ± 10% RH in the ambient mode.
9.2.2.2. The whole vehicle test chamber should be under good ventilation, and the air
exchange rate should be twice per hour or higher. The interior materials of the whole
vehicle test chamber shall have no appreciable emissions regarding the indoor air
inside the test vehicle, see Paragraph 8.3.8. about measuring the background
concentration. The probe is positioned 1.0m from the vehicle, see Paragraph 9.4.1.1.
for when and Annex I for where to take the measurement.
9.2.2.3. The heating of the interior of the cabin and the surfaces of the test vehicle is performed
by solar load radiators from outside the test vehicle during the driving mode.
9.2.3. Preconditioning of the Test Vehicle
9.2.3.1. The essential conditions for the surroundings are as follows. The temperature during
the ambient mode is adjusted to 23.0 to 25.0°C, as close as possible to 25.0°C via the
whole test chamber conditioning system. The preconditioning is started by opening the
door for 30 to 60min. After this, the door is closed for 16h ± 1h soak time, see Annex III.
9.2.4. Background Samples and Field blanks
9.2.4.1. Prepare the background samples and field blanks before the measurements are
started, see Paragraph 8.5. Install background sorbent tube samples for VOCs and one
DNPH cartridge for carbonyl compounds in the sampling trains to measure the
background concentration of the whole vehicle test chamber. The field blanks shall be
handled in the same way as those used for VOC or carbonyl compound
measurements, but without drawing air through the sampling trains. The field blanks
samples shall remain sealed and retained for analysis with the interior air samples.
9.2.4.2. Perform at least one field blank set for each measurement series. Analytical GC–MS or
HPLC blanks shall be performed according to Paragraph 8.5.

9.4.1.4. Turn off the pumps for the VOCs and carbonyl compounds sampling, read and register
the measurement volumes and take the VOC sorbent tubes and DNPH cartridges,
which are placed outside the vehicle cabin, out of the sampling train. Seal the sorbent
tubes or cartridges and analyse according to ISO 16000-6 and ISO 16000-3.
9.4.2. Parking Mode
9.4.2.1. Start the parking mode with the heating-up procedure. The following tasks shall be
performed. Start heating with the heating radiators, see Paragraph 8.2. The irradiation
is adjusted to 400W/m ± 50W/m and maintained at that level for 4.5h, see Annex III.
Adjust the air exchange rate to twice per hour or higher; this is a recommended value
for the whole vehicle test chamber.
9.4.2.2. Install the two DNPH cartridges in the two sampling trains for the test vehicle
measurement and two for the whole vehicle test chamber. Before the sampling begins,
check the sampling train for leaks, see Paragraph 8.3.3. and purge the dead volume.
Turn the pumps of the four sampling trains on. Perform formaldehyde sampling in the
test vehicle cabin at elevated temperatures for 30min. The flow rate is adjusted to
maximum 1.0l/min for carbonyl compound measurements. The measurement
procedure specified in ISO 16000-3 shall be followed.
9.4.2.3. Turn off the pumps for the formaldehyde sampling and take the DNPH cartridges out of
the sampling train to be analysed according to ISO 16000-3. Read and register the
measurement volumes.
9.4.3. Driving Mode
9.4.3.1. Before starting of driving mode, install the two VOC sorbent tubes and the two DNPH
cartridges, check the sampling train for leaks, see Paragraph 8.3.3. and purge the dead
volume. Connect the exhaust pipe of the test vehicle with the ventilation system of test
chamber to remove the exhaust gases outdoors.
9.4.3.2. Open the driver's door, start the engine. Turn on the air conditioning. Set vehicle
temperature at 23°C in the case of an automatic conditioning system or the lowest
operation for semi-automatic and manual conditioning systems. For test vehicles
without automatic air-conditioning systems, the fan is in highest performance mode with
fresh-air ventilation, see Annex III. Close the driver's door. Complete these steps of the
procedure in 60s; meaning, after a maximum of 60s of engine running the driver's door
shall be closed. The doors and windows of test vehicle shall remain closed during the
entire driving mode. Engine must be running during the entire mode at the vehicle's
idling speed with the minimum frequency of idling declared by the manufacturer.
9.4.3.3. After 60s of closing the door, turn on the pumps of the four sampling trains, two for
VOCs and two for carbonyl compounds, each in parallel. The sampling of air samples
in the test vehicle cabin is performed at elevated temperature for 30min. The flow rate
is adjusted to maximum 0.2l/min for VOCs and 1.0l/min for carbonyl compound
measurements. The measurement procedures specified in ISO 16000-6 (VOCs) and
ISO 16000-3 (carbonyl compounds) shall be followed.
9.4.3.4. Turn off the engine. Stop the pumps of the sampling trains and the heating
radiators/lamps. The sampling volumes shall be read and registered. The VOC sorbent
tubes and DNPH cartridges shall be taken out of the sampling train for the analysis as
specified in ISO 16000-6 and ISO 16000-3. Stop the continuous measurements for
temperature and relative humidity. This is the end of the test mode.
