General specification for building curtain walls,
windows and doors
1 Scope
This standard specifies the performance classification and selection,
requirements and tests of building curtain walls, doors and windows.
This standard applies to curtain walls, doors and windows, for civil buildings.
This standard does not apply to the external wall decoration systems, whose
panels are directly pasted to the main structure AND the external wall dry
hanging systems without supporting frame structures. It does not apply to
special doors and windows, such as fire doors and windows, escape doors and
windows, smoke exhaust windows, radiation shielding doors and windows.

3 Terms and definitions
The terms and definitions as defined in GB/T 5823 and GB/T 21086, as well as
the following terms and definitions, apply to this document.
3.1
Similar design
Characteristics of the design of curtain walls, doors and windows profiles,
glass, hardware and other parts or assembly methods, the change of which
does not cause performance changes.
3.2
Representative sample
A sample, that can represent the performance test results of similar curtain
walls, doors and windows, with similar design.
3.3
Fire resistant integrity of windows and doors
Under the standard fire resistance test conditions, the ability to prevent
flames and hot gas, from penetrating or appearing on the fire-back side,
within a certain period of time, when one side of a building's doors and
windows is exposed to fire.
4 Performance classification and selection
The performance classification and selection of curtain walls, doors and
windows shall meet the requirements of Table 1.
standards.
5.1.2 The design service life of main components, such as building curtain walls,
door and window panels, profiles, etc. shall not be less than 25 years.
5.1.3 The fire and lightning protection requirements of the building curtain wall
shall meet the requirements of GB 50016 and GB 50057.
5.1.4 The toughened glass used for building curtain walls shall meet the
requirements of JG J102. The toughened glass used for doors and windows
shall meet the requirements of GB 15763.4.
5.1.5 For exterior doors and windows with fire resistant integrity requirements,
at least one layer of glass used shall meet the requirements of GB 15763.1. For
the plastic exterior doors and windows, aluminum-plastic composite exterior
doors and windows, steel-plastic co-extruded exterior doors and windows,
aluminum-plastic co-extruded exterior doors and windows profiles, the
reinforced steel or aluminum lining used shall be connected into a closed frame.
