Leisure accommodation vehicles - Requirements and evaluation methods for odor, volatile organic compounds, aldehydes and ketones in vehicle
1 Scope
This document specifies the technical requirements and evaluation methods for interior odor, volatile organic compounds, and aldehydes and ketones in recreational vehicles.
This document applies to recreational vehicles.
2 Normative References
The contents of the following documents become essential provisions of this document through normative reference herein. For dated references, only the edition corresponding to that date applies. For undated references, the latest edition (including all amendments) applies.

3 Terms and Definitions
The terms and definitions defined in GB/T 22550 and the following apply to this document.
3.1 Odor
A pleasant or unpleasant olfactory sensory experience caused by compounds emitted into the air by materials, automotive components, or the entire vehicle interior.
3.2 Volatile Organic Compounds (VOCs)
Volatile compounds sampled using Tenax TA or equivalent adsorbent tubes, analyzed by non-polar or weak-polar capillary chromatographic columns (polarity index less than 10), with retention times between n-hexane and n-hexadecane.
[Source: HJ/T 400-2007, 3.2, modified]
3.3 Aldehydes and Ketones
A general term for compounds containing carbonyl functional groups that can be detected using the methods specified in Appendix C of HJ/T 400-2007, such as formaldehyde, acetaldehyde, acetone, acrolein, propionaldehyde, crotonaldehyde, butanone, butyraldehyde, methacrolein, benzaldehyde, valeraldehyde, methylbenzaldehyde, cyclohexanone, hexanal, etc.
[Source: HJ/T 400-2007, 3.3, modified]
3.4 Total Volatile Organic Compounds (TVOC)
The sum of volatile organic compounds sampled using Tenax TA or equivalent adsorbent tubes, analyzed by non-polar or weak-polar capillary chromatographic columns (polarity index less than 10), with retention times between n-hexane and n-hexadecane.

4 Technical Requirements
4.1 Interior Odor in Recreational Vehicles
4.1.1 When tested according to 5.4.2 d), the odor rating within 10 seconds and at 60 seconds shall both be less than or equal to 3.5. When tested according to 5.4.2 e), the odor rating within 10 seconds and at 60 seconds shall both be less than or equal to 3.0.
4.1.2 Based on the evaluators' personal perception, the types of odors perceived shall be identified. At least half of the evaluators shall not report the presence of unpleasant odors in their assessments.
Note: Odor types include asphalt odor, fishy odor, rotten egg odor, musty odor, sour/rancid odor, burnt odor, rubber odor, gasoline/engine oil/diesel odor, solvent odor, creamy odor, genuine leather odor, artificial leather odor, spicy odor, fermented/alcohol odor, sweat odor, etc. Among these, asphalt odor, fishy odor, rotten egg odor, musty odor, sour/rancid odor, and burnt odor are considered unpleasant odors.
4.2 Interior Volatile Organic Compounds and Aldehydes and Ketones in Recreational Vehicles
The levels of volatile organic compounds and aldehydes and ketones inside recreational vehicles shall meet the requirements specified in Table 1.
Table 1 Standard Values for Interior Volatile Organic Compounds and Aldehydes and Ketones in Recreational Vehicles
5 Evaluation Methods
5.1 Requirements for Vehicles Under Inspection
5.1.1 Vehicles under inspection shall be newly produced and within 28 days ± 5 days after coming off the production line, and the vehicle interiors shall not have been altered by sellers, users, or others.
Note: The vehicle off-line time of 28 days ± 5 days specified in this document refers to the period from the date on the vehicle certificate of conformity to the time of interior air sample collection.
5.1.2 From the time the vehicle comes off the production line until the collection of interior samples, no artificial treatments that may affect the emission of volatile pollutants inside the vehicle (such as temporarily placing adsorbent materials or purification devices inside) shall be performed, unless such treatments are part of the manufacturing process or transportation process specified by the manufacturer.
5.1.3 The type and quantity of fuel in the vehicle's fuel tank shall be added according to the manufacturer's specifications.
5.2 Environmental Requirements
5.3 Preparation of Vehicles Under Inspection
5.3.1 Remove surface coverings from the interior components of the vehicle (such as plastic films used to protect seats, carpets, etc., during factory shipment), and move these coverings outside the sampling environment chamber. For double-deck recreational vehicles, the pop-up roof shall be raised.
5.3.2 Place the vehicle under inspection in the environment specified in 5.2.
5.3.3 Fully open all openable windows and doors of the vehicle under inspection. After the temperature and humidity inside and outside the vehicle have reached equilibrium, leave the vehicle in this condition for 6h ± 0.5h.
5.3.4 When evaluating multiple vehicles simultaneously, their parking orientations shall be consistent.
5.4 Interior Odor Test Method
5.4.1 Odor Evaluation Requirements
5.4.1.1 Odor evaluators shall pass the odor evaluator qualification assessment test specified in Appendix A and undergo regular training.
5.4.1.2 Odor evaluators shall arrive at the evaluation site 30 minutes before the start of the evaluation.
