The reporter learned from the 2015 Fifth In-Car Air Quality and Forbidden Materials Technology Summit held on March 26 that the current recommended “Guidelines for Air Quality Assessment in Passenger Cars†is expected to be upgraded to national compulsory standards, plaguing consumption. The problem of air pollution inside the car for many years is expected to be effectively solved.
The summit was jointly organized by Bianmu Automobile, Beijing Quality Inspection Institute and Ministry of Industry and Information Technology, and supported by Beijing Hyundai, Beijing Auto and Great Wall Motor. With the rapid increase in the number of car ownership in China in recent years, the problem of air quality in car interiors has received increasing public attention. Experts and car manufacturers discussed in-depth discussions on the revision of air quality standards in vehicles, improved solutions for volatile organic pollutants (VOC) in vehicles, and low-VOC material replacement technologies.
Upgrade from recommended to mandatory
In September 2012, some media revealed that 300 owners collectively complained about the excessive formaldehyde in Mercedes-Benz vehicles.
Last year, the China Consumers Association teamed up with the Shenzhen Consumer Council to refer to GB/T27630-2011 "Guidelines for Air Quality Assessment in Passenger Cars" to test the air quality of 51 cars. The results show that there are 31 cars. The test value is lower than the limit of the standard, and the pass rate is 60.8%.
At the National People's Congress this year, the National Federation of Industry and Commerce Automobile and Motorcycle Parts and Accessories Industry Association submitted the "Proposal on Solving Air Pollution in Automobiles".
Whether it is imported luxury cars, joint ventures or autonomous cars, the air quality inside the car is becoming more and more worrying. Leather in the seat, foaming sponge, plastic parts such as instrument panel and door lining, chemical fiber components in roof felt and foot pad, and various adhesives used in the production process. They carry substances and gases that are harmful to health. The most common are organic compounds such as polycyclic aromatic hydrocarbons, formaldehyde and benzene.
As early as October 2011, the Ministry of Environmental Protection and the General Administration of Quality Supervision, Inspection and Quarantine jointly issued GB/T27630-2011 "Guidelines for Air Quality Assessment of Passenger Cars", which was officially implemented on March 1, 2012. The guidelines clearly stipulated The limit of the concentration of 8 common volatile organic compounds in benzene, toluene, xylene, ethylbenzene, styrene, formaldehyde, acetaldehyde and acrolein in the air of the car. This is the first recommendation for the evaluation of air quality in the car in China. Sex standard.
Since the guideline is only a recommendation standard and not a mandatory standard, the standard is neglected by many auto companies. Under the driving of some economic interests, some auto companies do not pay attention to the improvement of air quality in the car, and the quality ratio of the interior environment of the car is neglected. Therefore, the air quality problem in the car has not been well solved. In the use of automobiles, it is often the case that even if the air quality of the car products produced by the enterprise exceeds the standard, the result of the air quality judgment of the car from some private testing institutions is often not recognized by the automobile companies because of the lack of authoritative third-party testing institutions. It is difficult to get compensation.
As the level of concern for the air quality in the car continues to increase, the relevant government authorities continue to increase the control of VOCs in the car. In 2014, the Ministry of Industry and Information Technology carried out the preparation of the “Volatile Organic Pollutants (VOC) Control Technology Policy†to clarify the responsibilities of the three parties of the whole vehicle, parts and materials enterprises. In the same year, the Ministry of Environmental Protection carried out the revision of the “Guidelines for Air Quality Assessment in Passenger Vehicles†and plans to issue it as a mandatory national standard by the end of 2015.
The problem is expected to be solved
How to effectively monitor the increasingly complex interior quality environment and give consumers a healthy ride environment has become an urgent problem for auto companies.
At the summit, China Quality Certification Center Tong Lingsheng introduced the progress of air quality evaluation of passenger cars carried out by CQC. Geely Automobile, Jianghuai Automobile and Bianhu Automobile VOC Research Center exchanged automobile VOC test methods and reduced VOC solution from design source. Practical experience in programs, automotive VOC control.
Xu Yaozong of China Automotive Technology and Research Center (hereinafter referred to as China Automotive Research Institute) introduced the "VOC Compliance Integration Solution". He told reporters that at present, most enterprises have many problems in the management of VOC, such as insufficient intelligence in detection data management, long rectification cycle, and high cost. In order to effectively solve the common technical problems in the industry, China Automotive Research Institute has researched and developed the first VOC environmental compliance system that integrates “data acquisition, analysis and simulation†based on the full investigation of enterprise needs. The system will greatly improve the existing VOC and odor data management modes of the enterprise, realize the unified and information management of test data, help enterprises maximize the value of data, quickly lock high-risk interior parts, and improve the efficiency of rectification.
The reporter also learned that in order to break through the bottleneck of VOC control technology in China's auto companies, and replace the cumbersome and inefficient reverse rectification mechanism with high-efficiency and green VOC forward simulation, China Automotive Research Institute will organize the establishment of auto-related enterprises and related universities. In-vehicle VOC simulation joint research group". The research group aims to achieve VOC “forward design†control, and establishes a VOC prediction simulation evaluation model in the vehicle by constructing a quantitative relationship between the interior parts and the VOC of the vehicle to achieve interior materials and parts in the new vehicle design stage. Give the purpose of evaluation and selection. After the model is established, it will help enterprises to greatly reduce the risk of trial production of new vehicles, reduce the number of reverse rectifications, quickly select compliance interiors, shorten the design and development cycle of automobiles, and significantly reduce the cost of enterprise control.
During the two-day summit, experts, researchers and representatives of car companies conducted a heated discussion on how to improve air pollution inside the car and VOC organic pollutants.
Car companies should take the initiative to disclose information
As early as recently, the China Consumers Association and the Shenzhen Consumer Council recommended that the relevant state departments clearly require automakers to identify VOC content when the new car is shipped from the factory, and indicate whether it meets the national standards for consumers to purchase. Reference. At present, there is a lack of testing standards for the air inside the car in the country or industry. It is recommended to first establish industry alliance standards, and according to the actual use environment of the car, develop a simple and low-cost test method, so that consumers can judge the VOC in the car. According to the basis, it is convenient for consumers to defend their rights. At the same time, it is recommended that automobile maintenance enterprises actively carry out the transformation of production lines to guide consumers to choose water-based paints when repairing automobiles, and reduce the harm of harmful substances in paints to consumers' health.
The problem of air quality in the car has become one of the four major problems in the quality of automobile products. The reporter learned that the AQSIQ is very concerned and is currently discussing the air quality problems in the car and the recall of the car. And carried out a technical analysis of some typical typical air quality problems in the car, initially accumulated some experience, and also summarized some problems. Such as the identification of odor inside the car, is pure odor or toxic and harmful; the identification problem of air quality pollution source in the car is single or multiple; the determination of personal safety, including standard and non-standard; AQSIQ clearly stated that if it appears If the problem does involve personal safety, then a recall of the problem vehicle is required. With the standard, the road to recall will be smoother.
At the forum, “the car company actively disclosed the air quality status of passenger cars†became the strongest appeal of the delegates.
