Compliance overview
Scope and applicability
This standard applies to the design, manufacture, and inspection of fixed dual power fire-protection water supply equipment, typically combining diesel and electric fire pump units. It is mandatory for manufacturers producing such equipment for the Chinese market. It does not apply to equipment configured with high-voltage electric motor fire pump units. The standard covers both diesel-electric (SDC) and diesel-diesel (SCC) combination types.
Technical requirements
The standard specifies comprehensive performance and component requirements for dual power water supply equipment. Key areas include basic parameters such as rated working flow and pressure, and control functions covering emergency startup, fire operation modes, and pump switching protocols. Equipment must feature mechanical emergency start and stop mechanisms independent of control circuits. It details requirements for fire pump units, diesel engines and their accessories (including fuel tanks, batteries, and cooling systems), and monitoring instruments. The standard introduces new Internet of Things (IoT) functionality requirements for remote status monitoring and data transmission, aligning with GB/T 25000.51-2016 for software quality. Additionally, it mandates specific insulation resistance, voltage withstand, and electrical interference resistance criteria for control devices. Environmental adaptability is also addressed, requiring equipment to withstand low temperature, high temperature, and constant damp heat conditions.
Testing methods
Testing methods include verifying basic parameters, control functions (startup, operation, exit, switching), and IoT capabilities. Key tests involve water supply capacity under rated pressure, continuous operation stability, and sealing and hydrostatic strength tests. Component-specific tests cover diesel engines, piping, valves, and control devices, including insulation resistance, vibration, and environmental adaptability tests.
FAQs
What products are regulated under GB 27898.5-2026?
GB 27898.5-2026 regulates fixed dual power fire-protection water supply equipment, which includes combinations of diesel and electric fire pump units (SDC) or dual diesel pump units (SCC). It excludes equipment with high-voltage electric motor fire pump units.
Are there any updates from the previous version of GB 27898.5?
Yes, this version replaces GB 27898.5-2011. Major updates include the addition of IoT functionality requirements, mechanical emergency operation mechanisms, insulation resistance, and electrical interference resistance criteria. It also revised control functions, pump capacity requirements, and diesel engine specifications.
Does GB 27898.5-2026 require IoT functionality for all equipment?
IoT functionality is optional but standardized. If equipped, the equipment must monitor its running status, transmit data via wired or wireless means to an application platform, and meet specific data collection frequency and software quality requirements as per GB/T 25000.51-2016.
