BS ISO 11485-1 pdf download Glass in building — Curved glass Part 1: Terminology and definitions
This part of lSO 11458 specifies terminology and definitions for curved glass used in general buildingconstruction,furniture, display and various other non-automotive applications,
2Terms and definitions
For the purposes of this document, the following terms and definitions apply.
curved glassbent glass (us)
sheet of annealed glass curved by a heating process
curved annealed glass
glass that is curved and then cooled slowly so that it recovers its initial mechanical characteristics
curved patterned glass
flat patterned glass that has been formed into a curved shape
curved wired glass
flat wired glass that is formed into a curved shape
curved insulating glass
two panes of curved glass that have been fabricated into an insulating glass unit
curved tempered glass
flat glass that is formed into a curved shape by heating above a specified temperature and then subjected to arapid and controlled cooling process in order to give it greatly increased resistance to thermal and mechanicalstress
ln this International Standard, the term “tempered” also means “thermally toughened”.
curved heat-soaked tempered glass
tempered curved glass that has been post-processed using a specified heat-soak cycle with the intent ofisolating possible nickel sulfide inclusions
curved tempered enamelled glass
curved tempered glass which has a ceramic frit fired into the surface during the tempering processNOTE 1 After tempering, the ceramic frit becomes an integral part of the glass.
NOTE2 The application of the ceramic frit may be by a continuous or discontinuous application,e.g,screen printing.
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.
curved chemically strengthened glass
flat glass that has been formed into a shape and chemically strengthened
curved laminated glass
assembly consisting of curved glass sheets joined together with cast-in-place resins or films
curved laminated tempered glass
assembly consisting of curved tempered sheets joined together with cast-in-place resins or films
curved safety glass
curved glass that in the case of accidental breakage, reduces the risk of cutting or piercing injuries and/oroffers 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 lSO 11485-2.2.14
“hollow” face of curved glass
“bulge” face of curved glass
angular measurement of a segment of a curve in degreesNOTESee Figure 1.
