1 Scope
This Part specifies the requirements, testing methods, inspection rules, packageing, marking, transportation and content of contracts (or orders) of power electrostatic spray-painted extruded aluminium alloy profiles for architecture.
This Part applies to aluminium alloy hot extruded profieles coated with thermosetting organic polymetr powder for architecture (hereafter referred to as power coating profiels).
Other aluminium alloy materials that carry similar applications and similar surface treatmetns may refer to and adopt the content of this Part.
