Compliance overview
Scope and applicability
GB 25287-2023 applies to the design, production, installation, testing, inspection, acceptance, operation, and maintenance of perimeter protection high-voltage grid devices. These devices are primarily utilized in specific high-security locations such as prisons and detention centers. This standard is mandatory for all manufacturers and operators of such security equipment in China. It does not apply to low-voltage electric fence systems.
Technical requirements
The standard defines the composition and classification of the high-voltage grid device, including control, display, and storage units. It mandates features like sectional management, touch-of-wire strike capability, short-circuit recovery, and networking with upper management platforms. Manufacturers must ensure alarm response times and backup power switching meet strict operational criteria. It specifies the requirements for warning output voltage, strike intensity (electric shock charge), strike current, strike duration, and strike interval time. The devices are categorized into basic and enhanced types based on their strike intensity. Engineers must verify that the output parameters align with the defined safety and control limits. The standard outlines strict installation requirements for low-voltage and high-voltage control boxes, metal wires, and supporting structures. It also details protection measures including over-voltage, over-current, and enclosure protection (IP55). GB/T 4208-2017 is referenced for enclosure ratings. Devices must operate reliably under specified temperature and humidity ranges. Electromagnetic compatibility requirements ensure the device neither emits excessive disturbances nor fails under common electromagnetic interferences, referencing GB 17625.1 and GB/T 4343.2-2020.
Testing methods
The standard outlines comprehensive testing procedures, including: - Functional tests to verify sectional management, touch-of-wire strike, and short-circuit recovery capabilities. - Output characteristic tests using standard test loads and oscilloscopes to measure warning voltage, strike charge, current, and timing parameters. - Insulation performance tests involving impulse voltage and power-frequency withstand voltage to ensure no destructive discharge occurs. - Environmental tests (low temperature, high temperature, constant damp heat) to validate operational reliability under extreme conditions. Testing must be conducted in accordance with the specified inspection rules for type, factory, system, and operational checks.
FAQs
What products are regulated under GB 25287-2023?
It regulates perimeter protection high-voltage grid devices, which are AC devices using charged networks to deliver controlled electric shocks, typically deployed in high-security perimeters like prisons.
Are there any updates from the previous version of GB 25287?
Yes, the 2023 version replaces the 2010 edition. Key updates include the addition of system inspection, acceptance, operation, and maintenance requirements, as well as revised terms for touch, short-circuit, and disconnection events.
What are the environmental operating conditions required by this standard?
The device must function normally in environments ranging from -20°C to +65°C with relative humidity up to 95%, provided there are no flammable or explosive gases.
