It is the solar heat obstructing property of door and window in summer. The shading property is denoted in shading coefficient (SC).
3.3
Shading coefficient of window
SC
Under the given conditions, it is the calorific power ratio of the indoor calorific power forms from the solar radiation (permeating from exterior door and window) and transparent glass with a 3mm thickness (permeating a same area under the same conditions).
Note: The given conditions indicate the test condition of glass sunlight spectra and computational condition of doorset and windowset shading coefficient.
3.4
Major load-bearing frame member
The main profile like transom , mullion and fan and the frame profile of composite door and window which bear and transfer the self- gravitation of door and window and the acting force of level wind load in the vertical plane of door and window.
3.5
Major profiles
It is the basic structure that composes the door and window frame system, fan frame member system, the unlocking fan or glass, supplemental profile, adnexal door and window frame, fan profile as well as the frame profile of composite door and window are assembled on it.
3.6
Supplemental profile
In the door and window system, it is the additional profile (such as glazing bead and tilting fillet, etc) which may transmit the force or carry out some kinds of functions, and the profile is inlaid or fixed on the main profile member.
3.7
Major load-bearing parts of profile crosssection
On the cross section of door and window profile, they are the connected stress sections, of the ventral shield, flange and those used to fix other members and installation kits, bear plumb and horizontal direction load force.
Note: The major load-bearing parts of profile crosssection are wall thicknesses of Class A and B which are stated in GB/T 5237.1.
3.8
Fittings for windows and doors
They are fittings and components which are used to assemble the door and window.
3.9
Bimetallic corrosion
It is a bimetallic corrosion which is formed in different poles (the poles are formed in different metals).
[GB/T 10123-2001, Definition 3.14]
3.10
Verification
It is an authentication that proves the stated requirements are met in the way of offering objective evidences.
