Today to share the knowledge of wireless class test specifications, which will also explain the wireless charger test standards, if you happen to solve the problem you are now facing, don't forget to pay attention to this site, now start!
< ul>1, frequency: For test methods A and B: sweep frequency in the full frequency range of 27MHz ~ 500MHz. For test method B, the upper limit of the available frequency, as determined by the geometry of the strip, must be considered, as described in section 3 of IEC 803 (i.e., Appendix E1 to this standard).
1. NCC belongs to TaiwanBay radio frequency certification, BSMI certification is Taiwan's security certification, are mandatory certification. How long the cost cycle is related to the specifications of the product, such as whether it is necessary to audit the factory, some do not need to audit the cycle will be faster, the cost is less, and some need to audit the cycle and cost will be relatively more. Get an evaluation with an agency you're familiar with.
2. Usually, the BSMI certification cycle is 3-5 weeks, but the expedited service can meet urgent needs at an additional cost. We promise to assist you with professional services, so that your products quickly meet the requirements of the global market. If you are planning to enter the Taiwan market or need to renew the certification of your existing products, please feel free to contact us.
3. BSMI is the abbreviation of "Bureau of Standards, Metrology and Inspection" of the Ministry of Economic Affairs of Taiwan. According to the announcement of the Ministry of Economic Affairs of Taiwan, from July 1, 2005, products entering the Taiwan area should implement electromagnetic compatibility and safety supervision in two aspects.
4, BSMI is the Taiwan Ministry of Economic Affairs Standard Inspection BureauBureau of Standards, Metrology and Inspection. Since July 1, 2005, Taiwan has implemented controls on electromagnetic compatibility and safety specifications.
5, from July 1, 2005, products entering the Taiwan area of China to implement electromagnetic compatibility and safety supervision in two aspects. BSMI certification is mandatory and products must meet safety, EMC and related testing before they can be authorized to use the BSMI mark. BSMI certification does not require factory audit.PSE certification has gradually become an important bridge between consumers and manufacturers to ensure that the safety performance of products meets the requirements of relevant regulations and standards.
2, PSE is a power safety engineer certification. The Power Safety Engineer Certification is a professional qualification that focuses on the field of power system safety. This certification is designed to ensure that engineers have sufficient theoretical knowledge and practical experience to design, operate and maintain power systems safely and efficiently. As the global demand for power safety and reliability continues to grow, so does the importance of this certification.
3, PSE certification is a mandatory safety certification in Japan, which ensures that electrical and electronic products comply with the safety requirements of Japan's Electrical and Material Safety Law (DENAN Law) or international IEC standards. According to Japan's DENTORL Law (Electrical Equipment and Safety Law), 498 different products must pass PSE certification and display the corresponding logo when entering the Japanese market.
4, PSE certification is the direct embodiment of Japan DENTORL law, any electrical devices and material products if you want to sell in Japan, must pass this strict audit to ensure consumersSafety and rights. Its importance is self-evident, is the product to successfully enter the Japanese market passport.
Conclusion: Wireless chargers do produce electromagnetic radiation, although the value is usually small, but should be wary of its possible cumulative effect. With the popularity of wireless charging technology, users are exposed to more and more radiation sources in daily life, such as mobile phones, computers, WiFi, etc., and long-term accumulation may have an impact on health. Wireless charging technologyTechnology and controversy With the development of the mobile Internet, the rise of wireless charging has led to discussions about electromagnetic radiation.
For the human body: wireless charging technology is safe and harmless to the human body. The resonance principle used by wireless charging is magnetic field resonance, which is transmitted only between coils resonating at the same frequency, and other devices cannot accept the band, in addition, the magnetic field used by wireless charging technology is itself harmless to the human body.
In fact, it is certain to tell you that the harm of wireless charging to the human body is very small, almost negligible. It's just like Wi-Fi and mobile phones that we use on a regular basisThe same as TV and other electronic products, and we do not exist between the transmitter and the receiver the radiation level is small, and the main frequency absorbed by the human body is inconsistent with the charging frequency, so we can not worry about the harm of wireless charging.
Does wireless charging technology radiate the human body? Does it cause cancer? Tests have proved that wireless chargers can indeed produce electromagnetic radiation, but the value is relatively small. Now users are exposed to more and more radiation: computers, tablets, mobile phones, WiFi, televisions, microwave ovens... The added radiation value is very high, if the user lives in this high radiation ring for a long timeIn the environment, it may cause serious harm to the body and mind. The staff of the Communications Department of the Ministry of Industry and Information Technology said that it is inevitable that the wireless charger has radiation, but since it has been listed, it means that it must meet international standards and will not cause great harm to the human body. For this view, He Guili, director of the Tel Laboratory of the Telecommunication Research Institute of the Ministry of Industry and Information Technology, agreed: "Wireless chargers as long as they are done in accordance with technical specifications, there will be no radiation harm to the human body." But there is a key problem.
The introduction of wireless class inspection specifications is here, thank you for taking the time to read the content of this site, more about wireless chargersDon't forget to find the information of the inspection standards and wireless filling inspection specifications on this site.
