Center Certification & Testing International
In the context of the accelerated integration of the global electronic products trade, the competition in the TWS headphone industry chain has shifted from a single product performance to a full-system certification layout. As a core component of lithium batteries, its CB certification is becoming a key threshold for manufacturers to break through the international market.
In the TWS headphone industry chain, battery safety is always the core lifeblood of product quality. As a passport to connect to the global market, UN38.3 certification is not only a simple compliance requirement, but also an intuitive reflection of the technical strength of the manufacturer. This mandatory standard, established by the United Nations Dangerous Goods Transport Recommendation, builds a safety line through eight rigorous test items, from vibration shock to extreme temperature changes, to verify the reliability of batteries in the transport process.
In the TWS headphone industry chain, the battery is a core component, and its compliance directly affects the market access and brand reputation of the product. According to data from the State Administration for Market Regulation, consumer complaints caused by battery problems in 2023 accounted for 23.6%, most of which involved lack of certification. For manufacturers, 3C certification is not only a legal entry threshold, but also a key line of defense to build market competitiveness.
With the growing demand for electric toys in the global market, manufacturers must ensure that their products meet the requirements of CE certification when entering the European market. CE certification is not only a recognition of product quality, but also a necessary pass to enter the European market.
In the ecosystem of electronic products, charging heads play a crucial role. As a bridge connecting the power supply and the equipment, its quality is directly related to the safety of the user and the service life of the equipment. Therefore, the manufacturer must pay attention to the quality control of the charging head, and through a professional quality inspection report to ensure that the product meets the standards.
With the rapid development of the electronic product market, laptop has become an important tool in people\'s work and life, and the adapter as one of its indispensable accessories, its quality is directly related to the safety of the overall product and user experience. Therefore, it is particularly important to carry out strict quality inspection of the notebook adapter. This article will introduce the quality inspection process and standards of notebook adapters in detail to help manufacturers ensure product quality and reduce potential risks.
GB 31241-2022 is a mandatory national standard in China, the full name of the \"Lithium-ion batteries and battery packs for portable electronic products Safety Technical Specification.\" The standard was originally published in 2014 and was revised in 2022 to be released as GB 31241-2022, replacing the older version. The standard is designed to ensure the safety of lithium-ion batteries and battery packs used in portable electronic devices and covers a wide range of products such as laptops, mobile phones, Bluetooth headsets and more.
With the rapid development of electronic products market, polymer batteries have been more and more widely used because of their high energy density, lightweight and portable characteristics. However, the safety of battery transportation is also increasingly attracting the attention of national regulators. In order to ensure the safety of batteries during transport, the International Air Transport Association (IATA) stipulates that all lithium batteries must pass the United Nations Manual of Tests and Criteria, Part III, Section 38.3 (UN38.3) tests before transport. This article will detail the process, requirements and importance of polymer battery UN38.3 certification to help battery manufacturers better meet international standards and ensure safe product transportation.
