With the advancement of technology and rapid development of 5g technology, more and more wireless devices have entered the lives of the public. Such as Bluetooth headsets, Bluetooth speakers and other Bluetooth-enabled products, 2.4G wireless mice, wireless keyboards and other drones, VR glasses, smart glasses, smart robots, smart hosts, smart watches and other devices, not only sell well in China, but also far Sell to Japan. Wireless electronic products have always had a high degree of fierce attention in the Japanese market. Wireless products need to pass telec certification before they can be sold in Japan. Then let\'s take a look at the items for wireless product telec certification testing?

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.

On September 1, 2020, the European Chemicals Agency (ECHA) launched a public comment on two potential substances of very high concern (SVHCs). The two substances reviewed in this review are tetraethylene glycol dimethyl ether and dioctyl tin dilaurate, stannane, dioctyl-, bis(cocoyloxy) derivatives, and any other stannane, dioctyl tin Group-, bis(fatty acyloxy) derivative, where C12 is the main carbon number of the fatty acyloxy moiety. The public comment will end on October 16, 2020, during which all stakeholders can submit comments to ECHA. The approved substances will be included in the SVHC candidate list as the 24th batch of substances.
