Compliance overview
Scope and applicability
This standard applies to fire rescue lighting lines equipped with a power supply system. It is specifically designed for luminous lines used in low-visibility environments, such as fire smoke, to guide escape routes. It is mandatory for manufacturers producing fire rescue lighting equipment for the Chinese market. The standard does not apply to lighting lines without a dedicated power supply system.
Technical requirements
GB 26783-2011 specifies comprehensive technical requirements for fire rescue lighting lines, covering both physical and electrical performance. The standard mandates a minimum luminous brightness of 10 cd/m² and requires directional markers every 2 meters to ensure effective escape guidance. For flashing models, the flashing frequency must be maintained between 1 Hz and 2 Hz. The standard also sets strict limits on physical and environmental resilience. The line body must withstand a tensile force of at least 300N and a compressive force of 700N without damage. Additionally, the surface temperature must not exceed 60°C during continuous operation to prevent secondary hazards. The line must also pass rigorous waterproof and climate adaptability tests, including high-temperature, low-temperature, and damp heat cycles. Electrical safety is another core focus. The insulation resistance between the line body and conductors must be no less than 50MΩ. For AC-powered models, the dielectric strength must withstand specified high-voltage testing without breakdown. Explosion-proof models must additionally comply with GB 3836.1.
Testing methods
The standard outlines specific testing procedures to verify compliance. Key tests include: Luminous Brightness Measurement using a photometer, Tensile and Compression Testing to verify mechanical durability, and Insulation Resistance and Dielectric Strength Tests for electrical safety. Environmental performance is evaluated through Climate Adaptability Tests (referencing GB/T 2423.1, GB/T 2423.2, and GB/T 2423.4) and a Waterproof Test using a specified water spray flow rate.
FAQs
What products are regulated under GB 26783-2011?
GB 26783-2011 regulates fire rescue lighting lines, which are luminous lines used in low-visibility environments like fire smoke to guide escape routes. These lines consist of a power supply system, luminous line body, and winding reel.
Are there any mandatory requirements in GB 26783-2011?
Yes, clauses 5.2 to 5.13 and 8.1.1 are mandatory. These cover critical performance aspects such as luminous brightness, flashing frequency, insulation resistance, tensile strength, and marking requirements.
Does GB 26783-2011 include requirements for explosion-proof lighting lines?
Yes, for lighting lines with explosion-proof performance, their explosion-proof characteristics must comply with the provisions of GB 3836.1. The model designation uses 'B' to indicate explosion-proof performance.
