BS ISO 11485-1 pdf download Glass in building — Curved glass Part 1: Terminology and definitions
1 Scope
This part of ISO 11458 specifies terminology and definitions for curved glass used in general building construction, furniture, display and various other non-automotive applications.
2 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
2.1
curved glass
bent glass (US)
sheet of annealed glass curved by a heating process
2.2
curved annealed glass
glass that is curved and then cooled slowly so that it recovers its initial mechanical characteristics
2.3
curved patterned glass
flat patterned glass that has been formed into a curved shape
2.4
curved wired glass
flat wired glass that is formed into a curved shape
2.5
curved insulating glass
two panes of curved glass that have been fabricated into an insulating glass unit
2.6
curved tempered glass
flat glass that is formed into a curved shape by heating above a specified temperature and then subjected to a rapid and controlled cooling process in order to give it greatly increased resistance to thermal and mechanical stress
NOTE In this International Standard, the term “tempered” also means “thermally toughened”.
2.7
curved heat-soaked tempered glass
tempered curved glass that has been post-processed using a specified heat-soak cycle with the intent of isolating possible nickel sulfide inclusions
2.8
curved tempered enamelled glass
curved tempered glass which has a ceramic frit fired into the surface during the tempering process
NOTE 1 After tempering, the ceramic frit becomes an integral part of the glass.
NOTE 2 The application of the ceramic frit may be by a continuous or discontinuous application, e.g, screen printing.
2.9
curved heat-strengthened glass
flat glass that has been formed into a shape and heat-strengthened
NOTE The specifications of curved heat-strengthened glass are under consideration.
2.10
curved chemically strengthened glass
flat glass that has been formed into a shape and chemically strengthened
2.11
curved laminated glass
assembly consisting of curved glass sheets joined together with cast-in-place resins or films
2.12
curved laminated tempered glass
assembly consisting of curved tempered sheets joined together with cast-in-place resins or films
2.13
curved safety glass
curved glass that in the case of accidental breakage, reduces the risk of cutting or piercing injuries and/or
offers residual resistance by retaining the glass fragments
NOTE 1 The curved glass can be tempered or laminated for example.
NOTE 2 Curved safety glass is classified according to ISO 11485-2.
2.14
concave
“hollow” face of curved glass
2.15
convex
“bulge” face of curved glass
2.16
angle
α
angular measurement of a segment of a curve in degrees
NOTE See Figure 1.
2.17
inner radius
R i
radius of concave face
NOTE See Figures 1 and 2.
2.18
outer radius
R e
radius of convex face
NOTE See Figures 1 and 2.
