Starting from April 1st, a number of important national standards such as photovoltaic power stations, centrifugal pumps for petroleum, petrochemical, and natural gas industries, multimodal transport services, tour boat services, and tea supply chain management will be implemented. These standards will provide standard support for leading and regulating the development of emerging and future industries, promoting the upgrading of traditional industries, improving the quality of transportation and tourism services, and protecting consumer rights and interests.

National standards related to photovoltaic power plants

The recommended national standard "Technical Requirements for Relay Protection of Photovoltaic Power Stations" (GB/T 32900-2025) specifies the overall requirements, configuration requirements, setting requirements, and setting management requirements for relay protection of photovoltaic power stations. The "Technical Specification for Remote Monitoring of Distributed Photovoltaic Power Generation Systems" (GB/T 34932-2025) is a recommended national standard that specifies the normal working conditions, system architecture, technical requirements, testing methods, as well as labeling, packaging, transportation, and storage of remote monitoring systems for distributed photovoltaic power generation systems. The recommended national standard "Safety Regulations for Photovoltaic Power Stations" (GB/T 35694-2025) specifies the safety requirements for equipment, facilities, operation, and maintenance of photovoltaic power stations. The implementation of the three standards is conducive to further standardizing the relay protection, remote monitoring, and operation maintenance of grid connected photovoltaic power plants, supporting the safe and stable operation of the new power system, and promoting the high-quality development of the photovoltaic power generation industry.

National standard for centrifugal pumps used in the petroleum, petrochemical, and natural gas industries

The recommended national standard for centrifugal pumps used in the petroleum, petrochemical, and natural gas industries (GB/T 3215-2025) specifies the classification and names, technical requirements, basic design, auxiliary equipment, and other related requirements for centrifugal pumps used in the petroleum, petrochemical, and natural gas industries. The implementation of standards will help further improve the manufacturing level of centrifugal pumps for petroleum, petrochemical, and natural gas in China, and ensure product quality.

National Standards for Quality and Evaluation of Multimodal Transport Services

The recommended national standard "Quality and Evaluation of Multimodal Transport Services" (GB/T 24360-2025) specifies the service principles, service guarantees, service requirements, and service quality evaluation of multimodal transport, and clarifies the service quality evaluation indicators and their calculation methods. The implementation of standards is conducive to improving the quality and level of multimodal transport services, and providing technical basis for relevant departments to carry out industry supervision and management.

National standard for service quality of tour boats

The recommended national standard "Quality Requirements for Tourist Boat Services" (GB/T 26365-2025) specifies the basic requirements, facilities, equipment and environment, reception services, explanations, service personnel and service management of tourist boat services. The implementation of standards helps to improve the level and quality of tourism services provided by tour boats, optimize the tourist experience, and is of great significance for the healthy development of tour boat tourism.

National Standard for Tea Supply Chain Management

The recommended national standard "Technical Specification for Tea Supply Chain Management" (GB/T 46114-2025) specifies the general principles, supplier selection and management, procurement, processing, packaging, warehousing, transportation and distribution, sales and other technical requirements for tea supply chain management. The implementation of standards is conducive to ensuring the quality level of the tea supply chain, improving the efficiency of tea supply chain management, and assisting the high-quality development of China's tea industry.
