China Automotive Health Index Framework Releases New Criteria for Interior Pollution Assessment

China News Service, September 21st, yesterday The "China Automotive Health Index (C-AHI)" test evaluation system framework was released at the China National Automobile Engineering Research Institute Co., Ltd. (hereinafter referred to as "China Steam Research") academic conference center in Chongqing. .

According to Wan Xinming, general manager of China National Automobile Research Institute, the China Automotive Health Index is developed by the China National Automobile Research Institute and is a third-party evaluation system based on auto consumers, auto companies, and national policies. It aims to provide fair, open, and truthful evaluations. Data to establish a new standard of Chinese automobile health.

The China Automotive Health Index always upholds the principle of serving the community as its foundation, and aims to enhance the environmental health and safety of the vehicle. It will give full play to the overlapping advantages of cross-industry cooperation to better lead the consumer trends of rational purchase and promote the healthy development of the industry.

New Attempt: From Consumer Health

Nowadays, more and more mature consumers are not only looking at the value, configuration and fuel consumption of the car, but also paying more attention to issues such as pollution in the car that affect the health of the occupants. The relevant complaints are not uncommon. How to quantify the level of pollution in the car and lead the healthy development of the industry?

Obviously, consumers need an intuitive, reliable and accurate evaluation system to provide a reference for their purchase; auto companies need an evaluation system to provide new impetus for their healthy development; China's auto industry needs new guidelines for auto health evaluation.

Focusing on the health effects of car pollution, under the guidance of the International Traffic Medical Association, China Automotive Research Institute led the research on China's auto health index and established a professional research team from the automotive industry, medical health and hygiene industries, and communications industry. With the support of the Army Military Medical University, a test evaluation was conducted to form the framework of the China Automotive Health Index System.

New Standard: Healthy cars need to be tested

China National Automotive Research Institute of Automotive Technology Co., Ltd. focuses on pollution sources that endanger the health of occupants in the vehicle. It quantitatively evaluates the two dimensions of VOC and EMR, and sensitizes the vehicle's particulate matter (PM2.5, etc.) and the interior of the vehicle. Sexual assessment (VAR) as an observation item focuses on subsequent studies. On the basis of research on the consumer market and technology development of the automotive industry powerhouse, after a lot of theoretical research and experimentation, it has condensed into a Chinese automobile health index system.

It is reported that the system explicitly and quantitatively relates the relationship between automotive products and the health of passengers from the aspects of health hazard risk, comprehensive pollution levels, interior odor intensity, and electromagnetic radiation levels, and evaluates the interior of the car from the viewpoint of the protection of car users. Environmental health risks to humans.

Health risk The VOC content of benzene and formaldehyde, which are strong carcinogens in the vehicle, is converted into health hazards under different conditions such as parking, light, and driving, and the risk level of formaldehyde and benzene in the vehicle to the occupants is assessed.

Comprehensive pollution levels were examined for comprehensive air pollution in the vehicle. Under the different working conditions, the “pentabenzene trialdehyde” (benzene, toluene, ethylbenzene, xylene, styrene, formaldehyde, acetaldehyde, and acrolein) under current Chinese standards are tested and the comprehensive pollution level of VOCs in the car is tested. Evaluation.

An olfactory observer was introduced in the assessment of the interior odor intensity level to evaluate the interior odor intensity levels after resting at room temperature and direct sunlight. The evaluation results reflect the effect of the superposition of various volatile organic substances in the vehicle.

The EMR part determines the electromagnetic radiation test point according to the habits of the occupants and maintenance personnel, and makes reference to the internationally-relevant guidelines with high recognition for evaluation.

The in-vehicle particulate matter (PM2.5, etc.) and sensitization evaluation were used as observation items to evaluate the airtightness, purification effect, and sensitization source of the vehicle, respectively.

New impetus: Leading the industry together to transform and develop

The framework of the China Automotive Health Index test and evaluation system released this time not only provides an intuitive reference for consumers to purchase cars, but more importantly, it will provide inputs for vehicle manufacturers to optimize product configuration and design, and at the same time provide information for the supervision and management of government agencies. To promote the full transformation of China's auto industry with the power of standards.

Prior to this, there were no mandatory standards for domestic pollution in the car, but car companies such as Changan and Geely have already taken the lead, introduced new models and new practices such as “breathing MPV” and “nose group”, and achieved good social benefits. . It is believed that with the “China Automotive Health Index”, more car companies will join in efforts to produce healthier cars and provide consumers with healthy and reliable products.

In the next step, the China Automotive Health Index Research Team will screen vehicles with large market holdings, high degree of consumer concern, and large amounts of complaints related to vehicle interior pollution to carry out system verification studies and health index evaluations, and publish detailed reports on specific vehicle evaluations in due course. China's auto health index system will also continue to iterate and upgrade according to the development of automotive technology and the innovation of detection methods, injecting new impetus into the transformation of China's auto industry.
