General specifications for building curtain walls, windows and doors
1. Scope
This standard specifies performance classification and selection, requirements and tests concerning curtain walls, windows and doors.
This standard is applicable to civilian use curtain walls, windows and doors.
This standard is either applicable to external wall decoration system with the panel directly affixed to the main structure or external wall hanging system without supporting frame or structure, nor applicable to special use doors and windows e.g., fire-proof windows and doors, escape windows and doors, smoke exhaust windows, ray shielding windows and doors, etc.
