With the continuous advancement of technology, desktop printers have become indispensable devices in the home and office. However, with its wide use comes higher requirements for environmental protection. In order to ensure that the use of hazardous substances in electrical and electronic equipment is limited, the European Union has introduced CE-RoHS certification. This article will explore why desktop printers need CE-RoHS certification and how to successfully obtain it.

Among the many components of a tablet computer, the battery is undoubtedly one of the most critical parts. It not only directly affects the battery life of the device, but also relates to the safety of the user. Therefore, it is important for tablet manufacturers to ensure the safety and quality of batteries. In the Chinese market, 3C certification (China\'s mandatory product certification) is an important standard that batteries must pass.

As a key component widely used in electronic devices, electric vehicles and energy storage systems, the safety and reliability of lithium batteries have attracted much attention. During the design and production process, lithium batteries need to undergo a series of rigorous tests to ensure their stability in a variety of use scenarios. Among them, the drop test is an important part of evaluating the mechanical strength and impact resistance of lithium batteries. However, whether all lithium batteries need to carry out a 1.2-meter drop test, there is no uniform answer to this question, and it needs to be judged according to the specific application scenario and product standards.

With the popularity of electric bicycles, the safety and compatibility of chargers have become the focus of consumers\' attention. In order to ensure the quality and safety of electric bicycle chargers, China has formulated GB 42296-2022 \"Technical requirements for electric bicycle chargers\" standard, which was formally implemented on September 1, 2022, aiming to standardize the technical requirements for electric bicycle chargers, improve product quality, and protect the rights and interests of consumers.

In modern life, Bluetooth speakers have become an indispensable part of our daily lives. Whether relaxing at home or outdoors, Bluetooth speakers can provide us with high-quality music enjoyment. However, in the face of a wide range of Bluetooth audio products on the market, how can consumers ensure that they choose a safe and reliable product? The answer lies in CB certification.

UN38.3 is a safety standard for the transport of lithium batteries developed by the United Nations Committee of Experts on the Transport of Dangerous Goods. For scooter batteries, this certification is crucial because it is directly related to product safety and market access. Through UN38.3 certification, it can ensure that the battery will not cause fire or explosion due to temperature changes, vibration, shock and other factors during transportation, so as to protect the safety of personnel and property.

In today\'s era of widespread electronic equipment, lithium batteries have become one of the most commonly used power sources because of their high energy density, long life and lightweight characteristics. However, the safety of lithium batteries is also increasingly concerned. In order to ensure the safety of lithium batteries during transportation and use, a series of strict standards and certifications have been developed internationally, the most famous of which is the UN38.3 certification.

With the rapid development of UAV technology, UAV battery as its core power source, security issues are increasingly concerned. In order to ensure the safety of drone batteries in international transportation and daily use, UN38.3 certification has become an important standard within the industry.
