What regulations should be followed for the production or import of wireless charging devices for sale and use in China?
Wireless charging equipment produced or imported for sale and use in China does not require model approval, but should comply with the technical indicators and application scenarios set forth in the Regulations, as well as product quality, electromagnetic radiation, and electrical safety laws, regulations, and national standards. At the same time, manufacturers should indicate product information, technical requirements, usage requirements, etc. in the product instructions (including electronic display instructions) and prominently mark or display the dedicated identification of wireless charging devices in electronic form.
Explosion of electronic products such as mobile phones and headphones, not far from you, how to effectively avoid it
How can we prevent explosions and protect our own safety when using electronic devices. Explosions actually have precursors. If you encounter these phenomena, it is recommended to stop using them and stay away from them.
1. When electronic products get hot, it should be noted that it is hot, not overheating. People can tolerate overheating, such as playing games while charging. At this time, the phone will be very hot, but they can hold it with their hands. If you stop charging and playing with the phone, the temperature of the phone can quickly decrease. This type of overheating is normal. If the fever persists and the hand feels hot to the touch, it is dangerous and must be removed immediately to avoid accidents and self harm. Do not expose these electronic products to direct sunlight inside the car, as they are also prone to explosions.
2. If you find electronic devices such as mobile phones, headphones, etc. emitting smoke, making a sizzling sound, cracking, bulging, etc., immediately throw them in an open and non flammable area to prevent explosions and fires.
3. The battery is afraid of collision. If the phone or power bank is subjected to violent impact, it is recommended to let it rest for a period of time. If there is no overheating and there is no problem with charging and discharging, it can be used again.
4. It is best not to place it at the bedside when charging at night, in case of accidents.
The above is how to prevent explosions and protect one's own safety when using these electronic devices. When choosing electronic products, it is important to choose big brands and avoid three no products. This not only ensures product quality, but also involves personal safety issues.
How much does it cost to obtain CE certification for a car navigation system? Which testing agency can do CE certification for car navigation systems?
Q: Which testing agency can do CE certification for car navigation systems?
Answer: There is a proprietary standard EN50498 testing for applying for CE certification for car products. You can contact the staff of Shenzhen Yi'ante Testing Technology Co., Ltd. for processing (0755-33156648). 2-3 samples and certification application forms are required for EN50498 certification of car products, with a cycle of 7 working days.
Introduction to Car Navigation System:
Car Navigation is a driving assistance device that can help users accurately locate their current location, calculate their travel distance based on a predetermined destination, and guide them to their destination through map display and voice prompts. The operation of the car navigation system mainly relies on the Global Positioning System (GPS). The car navigation system is mainly composed of chips, antennas, processors, memory, and screens.
The operation of GPS navigation system also requires a car navigation system. Having a GPS system alone is not enough. It can only receive data sent by GPS satellites, calculate the user's three-dimensional position, direction, motion speed, and time information, and lacks path calculation capability. In order for the GPS receiver device in the user's hand to achieve route navigation function, a complete car navigation system including hardware equipment, electronic maps, and navigation software is also required.
EN50498， This standard specifies the first form of certification (i.e. CE self declaration) in the form of EN coordination standards, and is applicable to products defined in clause 3.2.9 of Appendix I of the 2004/104/EC Automotive EMC Directive. For example, car chargers, car refrigerators, heaters, car audio-visual entertainment products, car FM transmitters, and so on, these consumer automotive electrical products can be sold to EU countries through CE certification.
The evaluation content of this standard includes four in vehicle testing items and related product family standards, broadband and narrowband electromagnetic radiation interference testing (CISPR25); Conducted transient emission test, conducted transient immunity test (ISO7637-2). Our company has conducted many CE application tests for automotive products, which can help enterprises obtain certificates smoothly!
Electromagnetic radiation disturbance test:
1. Broadband radiation disturbance
2. Narrowband radiation disturbance
3. Conducted transient emission test
4. Conducted transient immunity test (ISO7637-2)
This test product only needs to meet the D level to meet the requirements. D level refers to the situation where the product has one or more abnormal functions after testing and needs to be manually restarted to function properly.

How do I charge for CE certification of wireless mice? Which testing agency can do CE certification for wireless mice?
How do I charge for CE certification of wireless mice? Which testing agency can do CE certification for wireless mice?
Q: Which testing agency can do CE certification for wireless mice? How to obtain CE certification for wireless mice?
Answer: You can call Shenzhen Yi'ante Testing Technology Co., Ltd. (0755-33156648) to inquire about the quotation for CE certification fees and testing cycles for related products.
The export of wireless mice to EU countries requires CE certification. Whether it is products produced by EU companies or products produced in other countries, in order to freely circulate in the EU market, CE labeling must be affixed.
Introduction to Wireless Mouse:
Wireless mouse refers to a mouse that is directly connected to the host through a wireless cable, using wireless technology to communicate with the computer, thereby eliminating the constraints of wires. Wireless communication methods are commonly used, including multiple wireless technology standards such as Bluetooth, Wi Fi (IEEE 802.11), Infrared (IrDA), ZigBee (IEEE 802.15.4), etc.
What are the instructions required for applying for CE certification for exporting wireless mice to the European Union
1. Electromagnetic compatibility testing (EMC testing): EMC=EMI+EMS, i.e. CE=LVD+EMC.
Low voltage products only require EMC, while high-voltage products require EMC+LVD.
2. Low voltage safety test LVD (new directive also requires this test for RF products with battery input).
LVD input voltage range:
AC 75-1500V
Direct Current (DC) 50-1000V
3. Conduct radio communication equipment testing (RF testing) according to European ETSI standards.
4. Notification of Spectrum Authorization in Europe.
5. CTR (TBR) testing.
6. Electrical safety and health protection testing (SAR assessment).
Introduction to CE certification mark:
The CE mark is a safety conformity mark rather than a quality conformity mark. It is regarded as a passport for manufacturers to open and enter the European market, and any product with the "CE" mark can be sold within each member state of the European Union without meeting the requirements of each member state, thus achieving free circulation of goods within the EU member states.
Industrial products that are required by the directive to bear the CE mark shall not be put on the market without the CE mark. Products that have already been marked with the CE mark and entered the market shall be ordered to be withdrawn from the market if they do not meet safety requirements. Those who continue to violate the provisions of the directive regarding the CE mark will be restricted or banned from entering the EU market or forced to withdraw from the market.
