For automotive products in China’s automotive industry there is no specific mandatory standards related to electromagnetics
The car also has electromagnetic radiation Some time ago about a car electromagnetic radiation exceeded the news, and owners who feel insecure. Although the final results show that it is just a false alarm, but to make people aware of the interior formaldehyde pollution, we will begin to accept the car of another more subtle but also more dangerous enemy electromagnetic radiation pollution . In fact, the modified improper is likely to be an important reason for the increase in car radiation. Therefore, the majority of owners to beware of car “invisible killer”, but also from the car modification and other aspects.
Frequency electromagnetic radiation limits, and work on the public environment since the 1990s, China has been taken to the International Radiation Protection Association recommended the limits 0.1mT (millitesla). In stark contrast to the more stringent standards of other countries, the UK National Radiological Protection Board official website of the risk value is set at 0.4T (micro-Atlas), the international recognition to the magnetic field strength in the children’s living environment should not go beyond this standard; Sweden is the first that the intensity of electromagnetic radiation in the 0.2T above will be harmful.
For automotive products in China’s automotive industry there is no specific mandatory standards related to electromagnetic radiation inside car prices in the production car will not be dedicated to the car electrical equipment on the human body radiation were detected, most is designed and manufactured in accordance with our country and internationally recommended reference standard on environmental public exposure limit ceiling 100T.
For the growing popularity of car navigation systems, in fact, a large electromagnetic radiation in the car. As the original navigator with good electromagnetic shielding electromagnetic radiation is the most prominent device in the car and more car owners car cameras and car dvr to install the navigation system, many of them ignore the electromagnetic shielding design of the “cottage” products that electromagnetic radiation they may greatly exceed the relevant limit value, causing serious harm to the human body.
Car navigation systems to excessive radiation, the following main reasons: a car GPS must receive the satellite signals to body positioning in order to achieve the navigation needs of the user’s body in the normal use Car GPS car consumer electronics products bound to the presence of electromagnetic radiation. And common household appliances, navigation, DVD products in which the working environment is very harsh, confined, environmental, shock, heat is very difficult, if the product pre-design focus to consider the issue of radiation, can reduce the energy reflection and overshoot, part of the energy through heat dissipation, reduce the energy radiated into space. Cross-radiation, electromagnetic waves between the navigation DVD products, mobile phones and other products from very close to the owners of different electronic products will interfere with each other in the car, the electrical focus placed togetherFree Articles, will result in a super-dose radiation in a confined car more likely to develop dangerous.
