Monitoring Central Station.
This Standard was approved by the General Administration of State Environmental
Protection on December 7, 2007.
This Standard was implemented from March 1, 2008.
This Standard shall be interpreted by the General Administration of State
Environmental Protection.
Determination of Volatile Organic Compounds and
Carbonyl Compounds in Cabin of Vehicles
1 Application Scope
This Standard specifies the arrangement of the sampling points for measuring the
volatile organic compounds and carbonyl compounds in crew cabin of motor vehicles,
sampling environment condition and technical requirements, sampling method and
equipment, corresponding measurement method and equipment, data processing,
quality assurance etc.
This Standard is applicable to the sampling and measurement of volatile organic
compounds and carbonyl compounds in cabin of vehicles in static state.
2 Normative References
This Standard cites the provisions of the following documents. For undated documents,
the latest edition of the normative document referred to applies.

3 Terms and Definitions
For the purpose of this Standard, the following terms and definitions apply.
3.1 Vehicles of categories M1, M2, M3 and N
Adopt the definitions in GB/T 15089.
M1–category vehicle refer to the passenger motor vehicles having four wheels, and the
seat number does not exceed nine, including the driver's seat.
M2–category vehicle refer to the passenger motor vehicles having at least four wheels,
and the seat number does not exceed nine, including the driver's seat, and the
maximum design total weight does not exceed 5000 kg.
M3–category vehicle refer to the passenger motor vehicles having at least four wheels,
and the seat number does not exceed nine, including the driver's seat, and the
maximum design total weight exceeds 5000 kg.
N–category vehicles refer to the cargo motor vehicles having four wheels.
3.2 Volatile organic constituent
4.4 Sampling procedure
4.4.1 Preparation stage of vehicles-to-be-tested
a) Place the vehicle-to-be-tested in sampling environmental chamber;
b) The covering (for example plastic film used to protect seats and carpet, etc.) on
the internal component surfaces shall be removed, and the covering shall be
moved out of the sampling environmental chamber.
c) Open the windows and doors (if they can be opened) of the vehicle-to-be-tested,
and keep the vehicle stationary for at least 6h;
d) During process of the whole preparation stage, the environment condition of
the sampling environmental chamber shall, at least in the last 4h, meet the
requirements of sampling technical condition specified in 4.1.2 of this Standard;
quality assurance measures meeting the requirements of 6.7 of this Standard
shall be taken to monitor environment condition.
4.4.2 Closing stage of vehicles-to-be-tested
a) Enter closing stage after preparation stage is completed;
b) Install sampling devices in the vehicle-to-be-tested according to the requirements
of 4.3.2 in this Standard; completely close the windows and doors of the
vehicle-to-be-tested to ensure tightness of the complete vehicle.
c) Keep the vehicle-to-be-tested closed for 16h, and then start collecting samples;
d) During the whole closing stage, the environment condition of the sampling
environmental chamber at where the vehicle-to-be-tested is located shall meet
the requirements of sampling technical condition specified in 4.1.2 of this
Standard; the environment condition shall be monitored according to the
requirements of 6.7 in this Standard.
4.4.3 Sampling stage
In sampling stage, the sampling environment condition shall meet the requirements of
4.1.2 in this Standard.
Use the packed column sampling tube of solid-phase adsorbent specified in Appendix
B of this Standard to collect volatile organic constituents; and use the packed column
sampling tube of solid-phase adsorbent specified in Appendix C of this Standard to
collect aldehyde ketone constituent. Respectively install packed column sampling
tubes on sampling system; and collect samples with constant-flow gas sampler.
When collecting volatile organic constituents with packed column sampling tube, the
sampling flow shall be 100 ml/min ~ 200 ml/min, and the sampling time shall be 30 min;
when collecting aldehyde ketone constituent with packed column sampling tube, the
sampling flow shall be 100 ml/min ~ 500 mL/min, and the sampling time shall be 30min.
6.5 On-site blank inspection
At least two sampling tubes shall be served as blank in each sampling, and shall be
equally treated as other sampling tubes. As on-site blank during the sampling process,
they shall be delivered to the laboratory together with other sampling tubes. On-site
blank value shall be determined during sa...
