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 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.

SRRC is a mandatory certification requirement of the National Radio Regulatory Commission. All radio component products sold and used in China must obtain Radio Type Approval Certification (Radio Type Approval Certification). All radio transmission equipment exported to my country or produced domestically must undergo SRRC certification and indicate the wireless transmission equipment model approval code; each radio transmission equipment model is issued with a unique \"radio transmission equipment type approval certificate\" and approval code. If the product has changes in performance or main technical parameters, SRRC certification must be re-certified.

A projector, also known as a projector, is a device that can project images or videos onto the screen. It can be connected to computers, VCDs, DVDs, BDs, game consoles, DVs, etc. through different interfaces to play corresponding video signals. So how should the projector be tested for RoHS?

A wireless mouse is a computer input device, divided into two types: wired and wireless. It is also an indicator of the vertical and horizontal coordinates of the computer display system. It is named \"mouse\" because it looks like a mouse. To apply for CE certification, the corresponding CE instruction for wireless products is the RED instruction; the following is an introduction to some related matters regarding the handling of CE-RED certification for wireless mice.

Smart bracelet is a fashionable technology product. Major electronic brands have also launched their own smart bracelets. The design is novel, avant-garde and beautiful. The most important thing is that the function of the bracelet is becoming more and more powerful. It can be used as people\'s daily healthy life. Reminders, such as: step counting, measuring distance, calories, fat, sleep monitoring, fatigue reminder, it can be connected to the mobile phone, for messages, call reminders, etc. But the smart bracelet is an electronic product, so it needs to pass the RoHS test to enter the EU.

On August 28, 2020, the National Certification and Accreditation Administration Commission issued an announcement from the CNCA on clarifying the mandatory product certification requirements for 5G mobile user terminals. The announcement clarified that 5G mobile user terminals belong to the scope of mandatory product certification, that is, 5G products are on the market. CCC certification is required before.
