Visão geral de conformidade

Esta visão geral está disponível por enquanto apenas em inglês.

Escopo e aplicabilidade

This standard applies to the design, manufacturing, and inspection of fixed fire-protection pressure boosting and pressure stabilizing water supply equipment equipped with low-voltage motors. It is mandatory for manufacturers producing fire water supply systems for the Chinese market. It specifically covers equipment used to maintain stable daily pressure in fire-protection networks or to boost water source pressure during fire-fighting operations. It does not apply to mobile or temporary fire water supply setups.

Requisitos técnicos

The standard specifies comprehensive performance requirements for fire water supply equipment, focusing on control functions, water supply capacity, and continuous operation stability. It mandates specific pressure maintenance limits and pump startup pressures to ensure reliable fire-protection readiness. Key component requirements are detailed for pneumatic water tanks, pump units, and control devices. The standard introduces new requirements for IoT functionality, requiring real-time monitoring of equipment status, data collection, and remote transmission to application platforms. Equipment must feature mechanical emergency operation mechanisms and robust electrical interference resistance. Additionally, it outlines strict criteria for sealing performance, hydrostatic strength, and operational noise limits. The control device must meet specific protection grades (e.g., IP31 or IP55 depending on the installation environment) and include dual power supply switching capabilities.

Métodos de ensaio

The standard defines rigorous testing procedures, including stabilizing operation tests, fire-fighting operation startup tests, and water supply capacity tests. It also mandates sealing performance tests (both hydrostatic and pneumatic) and hydrostatic strength tests to verify structural integrity. New test methods are introduced for IoT functionality, verifying data acquisition frequency and remote transmission capabilities. Furthermore, the standard requires insulation resistance and withstand voltage tests, electrical interference resistance tests, and environmental adaptation tests (low temperature, high temperature, constant damp heat, and vibration) to ensure durability under various conditions.

Perguntas frequentes

What products are regulated under GB 27898.3-2026?

GB 27898.3-2026 regulates fixed fire-protection pressure boosting and pressure stabilizing water supply equipment equipped with low-voltage motors, including their pneumatic tanks, pump units, and control devices.

Are there any updates from the previous version of GB 27898.3?

Yes, compared to the 2011 version, this 2026 edition introduces requirements for IoT functionality, mechanical emergency operation mechanisms, insulation resistance, and electrical interference resistance. It also updates terminology, product classification, and control function requirements.

Does GB 27898.3-2026 require IoT functionality for all equipment?

The standard includes provisions for IoT functionality as an optional feature (indicated by an 'IoT' suffix in the model). If equipped, the device must monitor its status, collect data at a frequency of no less than 1Hz, and transmit it to a data application platform without allowing remote control of valves or pumps.
