Compliance overview
Scope and applicability
This standard applies to the design, manufacturing, and quality inspection of fire resistant windows with lighting functions used in buildings. It covers various material types including steel, wooden, steel-wood composite, and aluminum alloy fire resistant windows. It is mandatory for manufacturers producing fire-rated windows for the Chinese construction market. The standard specifically categorizes applications into internal windows, external windows for general use, and external windows for refuge floors (rooms).
Technical requirements
The standard specifies comprehensive technical requirements across several categories. For key materials, it mandates minimum nominal thicknesses for steel profiles (1.2mm and above) and aluminum alloy profiles (1.8mm for external windows, 1.4mm for internal windows), alongside strict combustion performance criteria for wood. Manufacturers must ensure all base materials meet these structural and fire-resistant thresholds. Regarding key components, the standard sets performance benchmarks for fire-resistant glass, sealing components, and hinges. Notably, it introduces specific requirements for the window sash closing control device, including its closing time, operational durability, and temperature control action performance. Automatic closing windows must reliably close within 60 seconds under fire conditions. For physical and basic performance, the standard regulates air permeability, water tightness, and wind load resistance. It also includes requirements for thermal insulation, sound insulation, and smoke tightness. A distinct requirement is introduced for refuge floor windows, which must undergo an anti-spray impact test following the fire resistance test to ensure structural integrity during firefighting operations.
Testing methods
The standard outlines various testing procedures to verify compliance. Dimensional deviations and appearance are checked using precise measuring instruments like calipers and ultrasonic thickness gauges. Basic physical performances such as air, water, and wind resistance are tested according to GB/T 7106. Fire resistance tests are conducted following GB/T 12513 and GB/T 9978.1, utilizing a standard time-temperature curve. For automatic closing windows, the test verifies the automatic closing time and reliable latching under fire conditions. Additionally, the standard specifies an anti-spray impact test for refuge floor windows, performed immediately after the fire test to assess post-fire structural stability.
FAQs
What products are regulated under GB 16809-2024?
The standard applies to fire resistant windows with lighting functions used in buildings, including steel, wooden, steel-wood composite, aluminum alloy, and other material types. It covers their design, manufacturing, and quality inspection.
What are the main updates in GB 16809-2024 compared to the 2008 version?
The 2024 version introduces the partial-insulated fire resistant window (Type B) category, adds requirements for aluminum alloy materials, includes new performance metrics like smoke tightness and sound insulation, and mandates anti-spray impact testing for refuge floor windows.
How does GB 16809-2024 classify the fire resistance performance of windows?
Fire resistance is classified into insulated (Type A), partial-insulated (Type B), and non-insulated (Type C). Performance times are now expressed in minutes (min) rather than hours, with integrity and insulation requirements evaluated according to GB/T 12513.
