In the field of public safety, the national standard of "General Technical Requirements for Disposable Mask Manufacturing and Packaging Production Lines" clarifies the classification of disposable masks, stipulates the size requirements of disposable masks, the breaking strength requirements of the connection between the mask belt and the mask body, and the qualified rate of finished products, etc. It will greatly improve the speed and quality of the automated production of disposable masks, and escort the epidemic prevention and control work. The national standard of "General Technical Conditions for Disinfectant Filling Production Line" is conducive to improving the safety and stability of disinfectant production equipment, improving the quality of disinfectant products, and effectively helping enterprises to rapidly increase their disinfectant production capacity, and continuously contributing to the prevention and control of the epidemic. Provide disinfectant products to ensure support. The newly revised national standard of "Safety Requirements for Electric Vehicles after Collision" addresses the potential safety hazards that are likely to cause fire and explosion when the power battery is installed at the rear of the vehicle. It adds the safety requirements and test methods for the rear collision of the vehicle, and modifies it at the same time. The scope of application of side collisions has been improved, and the requirements for protection against electric shock have been improved, which is conducive to improving the safety technology level of electric vehicles in my country and effectively guaranteeing the safety of consumers’ lives and properties. In addition, the "Principles for the Design and Evaluation of Fire Protection and Explosion Protection of Offshore Installations", "Nuclear Power Plant Safety Level Power System Guidelines", "Nuclear Power Plant Safety System Reliability Analysis Requirements", "Guidelines for Personal Safety Constraints in Electrical Operation Sites", and "Guidelines for Early Warning of Electrical Safety Risks" were issued. "Environmental Test Methods and Severity Levels of Fire Electronic Products" and other national standards.
In the field of green sustainability, two national standards such as "Echelon Utilization of Vehicle Power Battery Recycling" can guide enterprises to carry out echelon utilization of power batteries, standardize product identification of echelon utilization, promote the maximum and efficient use of resources, and avoid the production of new products. Resource consumption, energy consumption and environmental load substances, and promote the healthy and sustainable development of the new energy automobile industry. In addition, a series of national standards such as "Ecological Technical Requirements for Recycling Polyester", "Bio-Natural Gas for Vehicles" and "Plastics" have been issued.
In the high-tech field, the national standard of "Automotive Driving Automation Classification" comprehensively considers multiple dimensions such as dynamic driving tasks, minimum risk strategies and design operation ranges, and divides the automotive driving automation levels into 0-5 levels, and prompts the cars to be under the corresponding level. The driving tasks that users should undertake are described in a more systematic and comprehensive way, which is conducive to enhancing consumers' understanding of autonomous driving technology, improving consumers' abuse and misuse, and improving driving safety. The national standard of "High-Strength and Toughness Alloy Structural Steel Rods Used in Deep-Sea Oilfield Drills" can further improve the overall technical level of my country's deep-sea oil and gas drills using alloy structural steel, accelerate industrial development, promote technological innovation, and enhance the domestic and foreign market competitiveness of products. In addition, "Conduction Vehicle Charger for Electric Vehicles", "Technical Requirements for Hybrid Power Supply for Electric Vehicles", "Top Contact Charging System for Electric Passenger Vehicles Part 1: General Requirements", "Aerospace Engineering Technology Maturity Evaluation Guidelines", "Aerospace Engineering Technology Maturity Evaluation Guidelines", "Regulations on the Maturity Rating of Stand-alone Products" and other national standards.
