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. GB/T 15089 Classification of Power-driven Vehicles and Trailers 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... ......
