Wireless products are electronic products that use radio technology and should include wireless signal transmission and reception systems. In daily life, mobile phones, wireless Internet devices, cordless phones, wireless walkie-talkies, etc. are all wireless devices, because they all include wireless signal sending and receiving systems. Before wireless products want to be legally sold in EU countries, they must perform tests in accordance with the RED directive to obtain approval, and they must also have CE-mark. Wireless remote control products must comply with the RED directive RED 2014/53/EU requirements.
A wireless keyboard is a Bluetooth device that transmits input information to a special receiver through infrared or radio waves without a direct physical connection between the keyboard body and the computer.For wireless products sold in the EU market, EU member states will adopt the New Radio Equipment Directive (RED) from June 13, 2016; wireless products that comply with the old R&RTTE Directive will be prohibited from being sold on the EU market.
The Chinese Model Approval is abbreviated as SRRC certification, which is a compulsory certification in China, which aims to distinguish between the civilian band and the military band in the wireless band. It is the technical management of the spectrum parameters and technical indicators of the radio transmission equipment before it is put into use in the development, production, import, and purchase links. Since June 1, 1999, radio component products sold and used in China must obtain radio model approval. Domestically produced, sold and used radio transmission equipment must be type approved, and the approval certificate and type approval code must be issued. The type approval code must be indicated on the label of the factory equipment.
MSDS is a chemical safety technical specification, which is a comprehensive description of physical and chemical data related to chemical characteristics. ZRLK can be entrusted to handle it.
Plastics can be said to be the natural enemy of nature, but human society cannot leave plastics. Many products require large amounts of plastics. The main component of plastic is resin. Resin refers to a polymer compound that has not been mixed with various additives. The term resin was originally named for the lipids secreted by plants and animals, such as rosin and shellac. The resin accounts for about 40% to 100% of the total weight of the plastic. The basic properties of plastics are mainly determined by the nature of the resin, but additives also play an important role. Some plastics are basically composed of synthetic resins, with no or little additives, such as plexiglass and polystyrene.
The CB system is a set of global mutual recognition system for electronic products established by the IECEE (International Electrotechnical Commission’s organization for conformity testing and certification of electrical products, English name The IEC System Conformity Testing and Certification of Electrical Equipment). Mutual recognition of test results to obtain national certification or approval, thereby promoting international trade.
The wireless walkie-talkie, or walkie-talkie, is a portable two-way radio transceiver, originally developed for military use. The main features include: half-duplex channel and press the button to transmit. The typical appearance is like a handheld phone, which is larger than an ordinary handheld phone, but only has a single device with an antenna on top. Hand-held transceivers have become very valuable communication tools for users such as police, emergency services, and industrial and commercial users. These services use dedicated frequencies. The walkie-talkie products use wireless transmission and wireless reception technology to transmit information. Then, in response to the srrc certification regulations issued by the National Radio Commission, it is unavoidable that walkie-talkie products with wireless transmission and wireless reception functions must be srrc certification.
Battery manufacturers or sellers need to provide customers with a professional battery MSDS certification report to reflect the physical and chemical parameters of the product, flammability, toxicity and environmental hazards, as well as information on safe use, emergency care and disposal of leakage, laws and regulations, etc., to help use Better control of risks. The battery equipped with high-quality MSDS can improve the safety of the product, and at the same time make the product more international and improve product competitiveness. Chemical safety technical description, this document is required to understand the characteristics of the product during general transportation. Product description, hazardous characteristics, relevant laws and regulations, permitted uses and risk management measures, etc., these basic information are included in the battery MSDS certification report.
