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.

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?
