The safety of electronic products such as mobile phones must comply with this new national standard

The State Supervision Administration (Standard Committee) recently approved the release of GB 4943.1-2022 "Audio and video, information technology and communication technology equipment part 1: Security Requirements" for compulsory national standards, which will be officially implemented on August 1, 2023. On July 26, the General Administration of Market Supervision held a special press conference to interpret the new national standard. Liu Xiangang, deputy dean of the China Institute of Electronic Technology Standardization, said: "The safety issues of electronic products used by consumers in daily life can find the corresponding technical requirements in this standard."

The new national standard has fully considered new technologies, new products, and new applications that are closely related to the safety of the people's personal property, and bring new security risks and hidden dangers.

For example, in recent years, the use of more and more widespread wireless charging functions has brought about security problems. Consumers may place metal items such as keys and coins on wireless chargers. Wireless chargers may allow metal items to produce high temperatures and burns, fire and other dangers through energy transmission. For this, the new national standard clearly requires that wireless chargers need to have the function of identifying metal foreign objects and stop energy transmission of foreign bodies in time.

For example, with the popularization of electronic equipment multimedia functions, mobile phones, headphones, Bluetooth headsets and other products with personal music player functions are favored by consumers. However, if wearing headphones, the volume of the headset is too large or the listening time is too long, which will cause harm to people's hearing. The new national standard puts forward safety requirements from the level of sound pressure levels of the headset to ensure consumers' listening health. For example, the new national standard requires that when the specified limit is above the specified limit within a certain period of time, electronic products should give warnings and request users to confirm, and automatically reduce the security volume without confirmation.

For another example, more and more portable electronic products have adopted rechargeable batteries, which brings hidden dangers such as overheating, burns, leakage, and explosions, which endangers the safety of the people's personal property. The new national standard has focused on battery safety issues, stipulating the safety requirements such as over charging protection, temperature protection, shell fire prevention, and falling protection of batteries. Safety issues such as leakage, combustion, and explosion caused by the above problems.

The original standards can no longer adapt to the rapid development of electronic products. With the rapid development of the new generation of information technology, the original "General Requirements" and "Audio, Video and Similar Electronic Equipment Security Requirements" also faced new problems: General Requirements: General Requirements: General Requirements: Audio, Video and Similar Electronic Equipment Security Requirements ":

On the one hand, smart phones, laptops, and smart TV electronic products have highly integrated functions. They often have audio and video and information communication functions. They are divided into two standards to evaluate the safety of production, testing and certification, market supervision and other aspects in two standards. Cause difficulties.

On the other hand, the International Electricity Commission (IEC) has merged the two international standards of audio and video product security and information technology product security according to the technological development trend. Use it as a basis for testing and certification and market access. If my country does not integrate and revised as soon as possible, and achieves international standards, it will adversely affect the export of electronic products in my country.

There are two main aspects of standards in the standard of standards:

On the one hand, the scope of applications has been further expanded. The new version of the standard integrates the original two compulsory national standards, covering all products of audio, video, information technology and communication technology equipment, and conforms to the current development trend of the technical industry.

On the other hand, technical optimization and upgrading are used. The new version of the standard uses the concept of safety engineering, put forward energy grading, and comprehensively considers the six aspects of electrical shocks, fire, overheating, and sound radiation in various electronic products during use. And put forward corresponding protection requirements and test methods to help the safety protection of electronic products precise, scientific, and standardized.

The release and implementation of the new version of the standard has three important significance:

First, it is conducive to the implementation standards of electronic product manufacturers. The scope of the previous two standards has different applications, which has caused many enterprises to produce and design electronic products in the production and design electronic products. After the merger of the new version of the national standard, it solved the problem of difficulties in the application of standards in the past, realized the "one ruler" of product production, testing, and spot checks, reducing the burden on the enterprise and improving the efficiency of market operation.

The second is to ensure the health and safety of consumers. The new version of the national standard has carried out in -depth, supplemented, and improved the core content of the original two standards. For new hidden dangers brought by new technologies such as wireless charging and Bluetooth headsets, according to the concept of the concept of dangerous sources classification, the specifics of the danger source classification are specified. Safety requirements and testing methods, protect the safety of personal property from many aspects such as anti -electric strikes, anti -fire, anti -heat, anti -sound light radiation.

The third is to promote the export trade of electronic products in my country. The new version of the standard modification uses international standard IEC 62368-1, which is consistent with the main technical content as the international. In accordance with the new version of the national standard, the production of electronic products can meet the requirements of the international security assessment system, eliminate the international trade technology barriers, and help my country's electronic products "go out".
