A total of 539 national standards have been implemented since March 1. Among them, the important standards in fields such as operator interfaces, BDS applications for agricultural machinery, graphical symbols for packaging and storage, management of fresh agricultural products in supermarkets, safety colors and signs, and fire dampers will provide strong technical support for protecting people’s health, lives and property.

In the field of AI operator interface, two voluntary national standards, GB/T 46069.1-2025, Artificial intelligence—Operator interface—Part 1: Basic mathematical classes, and GB/T 46069.2-2025, Artificial intelligence—Operator interface—Part 2: Neural network classes, specify the parameter information, programming languages, interface consistency, data structures, interface lists, interface operations and parameters for basic mathematical and neural network operator interfaces in the artificial intelligence field. These standards will improve the compatibility between software and various mainstream AI processors, and promote the sound development of the AI software and hardware ecosystem.

In the field of BDS application in agricultural machinery, the voluntary national standards GB/T 46268-2025, Agricultural machinery operation monitoring system based on BDS, and GB/T 46270-2025, Agricultural machinery automatic driving system based on BDS, define the composition, technical requirements, test methods, inspection rules, as well as marking, packaging, transportation and storage of agricultural machinery operation monitoring system and automatic driving system based on BDS respectively. The two standards will help standardize the R&D, configuration, installation and inspection of relevant agricultural machinery products, improve the accuracy and efficiency of agricultural machinery operation, and boost the rapid development of the intelligent agricultural machinery equipment industry in China.

In the field of graphical symbols for packages, the voluntary national standard GB/T 191-2025, Graphical symbols marking for handling and storage of packages, specifies the names, styles, connotation, dimensions, colors and application methods of graphical symbols for handing and storage of packages. It will improve the stability of packaged goods during storage and transportation, reduce safety accidents such as damage and leakage caused by improper packaging, and protect product safety as well as the personal safety of transport personnel and consumers.

In the field of the management of supermarkets, the voluntary national standard GB/T 22502-2025, Management technical specification for marketing fresh agricultural products in supermarket, specifies the requirements for environmental layout, facilities and equipment, tools, containers and materials, operation management, evaluation and improvement of fresh agricultural products in supermarkets. It will help ensure the safety and sanitation of fresh agricultural products in supermarkets, allowing consumers to purchase with confidence.

In the field of safety signs, the mandatory national standard GB 2894-2025, Safety colors and safety signs, defines the colour representations for conveying safety information, types, installation and application requirements of safety signs, as well as basic identification colors and symbols for industrial pipelines. It will further standardize the use of safety colors and signs, enhance the public’s ability to identify risks, and reduce work safety accidents.

In the field of fire dampers, the mandatory national standard GB 15930-2024, Fire dampers for building venting and smoke-venting system, is applicable to fire dampers used in ventilation and air conditioning systems, and kitchen fume exhaust systems in industrial and civil buildings as well as underground structures. The standard defines the classification, materials, accessories, appearance and tolerances, technical requirements, test methods, inspection rules, marking, packaging, transportation and storage of such fire dampers. It will provide a technical basis for the production and inspection of relevant fire damper products, help improve product quality, and effectively protect people’s lives and property in the event of a fire.
