A series of significant national standards have come into force starting April 1st. These standards cover various sectors including photovoltaic power stations, centrifugal pumps for the petroleum, petrochemical, and natural gas industries, multimodal transport services, excursion vessel services, and tea supply chain management. The implementation of these standards is expected to provide foundational support for guiding and regulating emerging and future industries, promoting the upgrading of traditional sectors, enhancing the quality of transportation and tourism services, and protecting consumer rights.
The recommended national standard "Technical Requirements for Relay Protection of Photovoltaic Power Stations" (GB/T 32900—2025) outlines the general requirements, configuration requirements, setting requirements, and management requirements for relay protection in photovoltaic power stations. The recommended national standard "Technical Specification for Remote Monitoring of Distributed Photovoltaic Power Generation Systems" (GB/T 34932—2025) specifies the normal operating conditions, system architecture, technical requirements, testing methods, as well as aspects related to marking, packaging, transportation, and storage for remote monitoring systems of distributed photovoltaic power generation. The recommended national standard "Safety Regulations for Photovoltaic Power Stations" (GB/T 35694—2025) defines the safety requirements for equipment, facilities, operation, and maintenance of photovoltaic power stations. The implementation of these three standards will help further standardize the relay protection, remote monitoring, and operational maintenance of grid-connected photovoltaic power stations, support the safe and stable operation of new power systems, and drive the high-quality development of the photovoltaic power generation industry.
The recommended national standard "Centrifugal Pumps for Petroleum, Petrochemical and Natural Gas Industries" (GB/T 3215—2025) stipulates the classification, nomenclature, technical requirements, basic design, and auxiliary equipment for centrifugal pumps used in these industries. The implementation of this standard will contribute to enhancing the manufacturing level of centrifugal pumps for China's petroleum, petrochemical, and natural gas sectors and ensure product quality.
The recommended national standard "Quality and Evaluation of Multimodal Transport Service" (GB/T 24360—2025) specifies the service principles, service guarantees, service requirements, and service quality evaluation for multimodal transport, clarifying the evaluation indicators and their calculation methods. The implementation of this standard is conducive to improving the quality and level of multimodal transport services and provides a technical basis for relevant authorities to conduct industry supervision and management.
The recommended national standard "Service Quality Requirements for Excursion Vessels" (GB/T 26365—2025) defines the basic requirements, facilities, equipment, environment, reception services, commentary, service personnel, and service management for excursion vessel services. The implementation of this standard will help enhance the service level and quality of excursion vessel tourism, optimize the tourist experience, and is significant for the healthy development of the excursion vessel tourism industry.
The recommended national standard "Technical Specification for Tea Supply Chain Management" (GB/T 46114—2025) outlines the general principles and technical requirements for supplier selection and management, procurement, processing, packaging, warehousing, transportation, distribution, and sales in tea supply chain management. The implementation of this standard will help ensure the quality level of the tea supply chain, improve management efficiency, and support the high-quality development of China's tea industry.
