Cruze radiating door needs a false standard for radiation
Recently, the topic of self-testing in-vehicle electromagnetic radiation intensity of a number of Cruze owners was hotly debated on the Internet, and the topic of health and safety in cars has once again become the focus of public opinion. The cause of the incident was that one of the netizens inadvertently measured the electromagnetic radiation in Cruze's car to 19μT, and the intensity of electromagnetic radiation in a substation within 3m was only 0.7μT.
Shanghai GM responded quickly and said in its official statement the next day that according to the sample test results of the physical and chemical environment analysis and research center of the Chinese Academy of Sciences, the magnetic field strength in Cruze's car is far lower than that in China and internationally recommended related reference standards. The upper limit of exposure limit 100μT will not affect human health.
Cruze has been a hot selling model of Shanghai GM since it was listed. This news has not only attracted the attention of many netizens who are waiting to see the car, but has also caused the industry’s hot debate on the electromagnetic radiation of cars. However, the most embarrassing thing in the whole incident is that at present, there is no authoritative standard for the evaluation of electromagnetic radiation in automobiles.
Cruze "lays a shotgun"?
Not long ago, a post titled "Stunned, Electromagnetic Radiation in Cruze Cars Is Very Large" triggered a hot debate in the automotive industry on car electromagnetic radiation at several automotive forums. According to this post, netizens themselves detected that the electromagnetic radiation intensity of the main driving position in Cruze's driving reached 19μT, while the electromagnetic radiation intensity within a 3m range of a Guangzhou substation detected by a professional agency was only 0.7μT. If the netizen's argument is true, the intensity of electromagnetic radiation inside the Cruze car is about 30 times that of the substation. However, due to the lack of professional authoritative data measured by the owner, many netizens also questioned this and called for authoritative testing agencies to intervene.
Shanghai General Motors quickly responded and issued a statement on Chevrolet Cruze’s in-vehicle electromagnetic radiation. On February 13th, commissioned by a third party, the Physical and Chemical Environmental Analysis Center of the Chinese Academy of Sciences carried out a sample inspection of the electromagnetic radiation in the Cruze car. The result showed that Cruze The magnetic field strength in the vehicle is far lower than the upper limit of 100 μT of the environmental public exposure limit in relevant reference standards recommended by China and the international community, and will not affect human health.
According to the test results of the Cruze vehicle sampled by the Physical and Chemical Environmental Analysis Research Center of the Chinese Academy of Sciences (“Zhong Ke Ye Zi (2012) No. 021309), the highest value of electromagnetic radiation in the Chevrolet Cruze 1.6SL is the transmission left The lateral position radiation is 0.1376μT, which is much lower than the self-tested 19μT. Its front and rear seats have 0.0341μT and 0.0261μT radiation respectively. In addition, the maximum value of the Cruze, which is a manual transmission 1.6T, is 0.417μT, and the left side radiation value of the 1.8SX automatic transmission is 0.191μT.
A staff member of the Shanghai General Motors Public Relations Department said in an interview with a reporter from the China Economic Times that the detection of electromagnetic radiation in vehicles must pass through authoritative professional organizations. As for some users self-test equipment, Shanghai GM declined to comment. He said that although there is no national standard for electromagnetic radiation in vehicles, auto parts have been rigorously tested before being assembled. The vehicles manufactured by Shanghai General Motors carry out a full set of electromagnetic compatibility (EMC) tests in accordance with GM's global standards, and pass electromagnetic compatibility (EMC) tests required by China's national type certification. At the same time, related automotive electronic components are in accordance with GM's global standards. , In the third-party laboratory approved by General Motors for parts and components including radiation, immunity, static electricity and other electromagnetic compatibility (EMC) related experimental certification. In addition, according to tests conducted by the Physical and Chemical Environment Analysis Research Center of the Chinese Academy of Sciences, the electromagnetic radiation in the Cruze car is far lower than the self-test results of netizens. Therefore, the owner can safely drive.
The Chevrolet Cruze model has been a hot-selling model since its launch. Since its launch in April 2009, it has sold more than 520,000 vehicles in less than three years; last year it sold more than 220,000 vehicles in China. Passenger car market ranked third in a single model. Only in January this year, Chevrolet Cruze’s sales exceeded 20,000 vehicles again in the sluggish environment of the entire automotive market. Therefore, in the current electromagnetic crisis, Cruze’s “lying shot†was interpreted by some netizens as "The car is red is not much," or it was framed by competitors.
Electromagnetic radiation standards in the car do not need to launch a serious violation of the Cruze electromagnetic radiation, the safety and health of the car once again pushed the public view, and even set off a wave of electromagnetic radiation is harmful to the human discussion.
Lin Jian, a senior engineer at the Department of Automotive Engineering at Tsinghua University, said in an interview with a reporter from the China Economic Times that electromagnetic radiation in automobiles generally refers to the radiation of electrical circuits inside cars. At present, there is no standard for electromagnetic radiation in automobiles, and whether electromagnetic radiation is harmful to the human body is still an unresolved issue. He said that at the moment, the impact of electromagnetic radiation discussed by our industry mainly refers to its impact on the operation of other electrical appliances in the surrounding area, rather than on the human body.
He pointed out that there is a large amount of electromagnetic radiation in our daily lives, such as mobile phones, Bluetooth, computers and other widely used appliances that have electromagnetic radiation. The electromagnetic radiation of the mobile phone is 100 milligauss, and the radiation of the computer is 20-40 milligauss. In the era of the mobile phone just emerged, the radiation of mobile phones was over-promoted by the crowd, and a number of radiation-protected products were also enthusiastic. But in the past, we are still using mobile phones and computers. Therefore, if you want to prevent electromagnetic radiation in your life, it is really “defense.†It is not necessary to cause panic.
Xu Jie, director of the Physical and Chemical Environment Analysis Research Center of the Chinese Academy of Sciences, stated that the Cruze 1.6T installed navigation GPS in the car, so the value may be greater than other models. He also said that during the driving of the car, some additional on-board equipment, such as car power supply and modified audio, will increase the radiation value. This is not very different from the usual use of some appliances at home.
Zhang Zhiyong, an automotive marketing expert, said that before the industry’s concern about car safety usually refers to how to avoid more losses when the car crashes into the outside world, but there is no specific research and standards on the electronic radiation within the car. This time Cruze was accused of in-vehicle radiation violations that triggered the attention of consumers and manufacturers to the safety of cars. The industry exposed in the entire incident did not have the standard, and urged the relevant government departments to formulate relevant information as soon as possible. Standards allow companies to follow regulations in the production process. This is not only responsible for the development of the automotive industry, but also responsible for consumers.
