ISO 12543:2011 EN Glass in Building Laminated Glass and Laminated Safety Glass

This part of ISO 12543 defines terms and describes component parts for laminated glass and laminated safety glass for use in building.

1   Scope

This part of ISO 12543 defines terms and describes component parts for laminated glass and laminated safety glass for use in building.

2   Terms and definitions

For the purposes of this document, the following terms and definitions apply.

NOTE Definitions 2.3 onwards apply to both laminated glass and laminated safety glass.

2.1 laminated glass

assembly consisting of one sheet of glass with one or more sheets of glass and/or plastic glazing sheet material joined together with one or more interlayers

2.2 laminated safety glass

laminated glass where in the case of breakage the interlayer serves to retain the glass fragments, limits the size of opening, offers residual resistance and reduces the risk of cutting or piercing injuries
See ISO 12543-2.

2.3 laminated glass with fire-resistant properties

laminated glass that does not achieve its fire resistance by means of interlayers, which react to high temperaturesNote 1 to entry: No glass product in itself can be classified as fire resistant. When the glass product is glazed into an appropriate frame system, the assembly can be tested and classified as fire resistant. This type of laminated glass can be used as a component in a fire-resisting glazed assembly.

2.4 fire-resistant laminated glass

laminated glass where at least one interlayer reacts to the high temperature to give the product its fire resistanceNote 1 to entry: This product can also contain glass components which are themselves fire resistant. No glass product in itself can be classified as fire resistant. When the glass product is glazed into an appropriate frame system, the assembly can be tested and classified as fire resistant. This type of laminated glass can be used as a component in a fire-resisting glazed assembly.

2.5 laminated glass with acoustic properties

laminated glass where at least one interlayer increases the sound transmission loss of the productNote 1 to entry: Sound transmission loss can be evaluated in accordance with ISO 22897.Note 2 to entry: The interlayer can be evaluated in accordance with ISO 16940, which measures the mechanical impedance of laminated glass.

2.6 symmetrical laminated glass

laminated glass in which, from both outer surfaces, the sequence of glass panes, plastic glazing sheet material and interlayer(s) by type, thickness, finish and general characteristics are the same

2.7asymmetrical laminated glass

laminated glass in which, from both outer surfaces, the sequence of glass panes, plastic glazing sheet material and interlayer(s) by type, thickness, finish and/or general characteristics is different

2.8 flat laminated glass

laminated glass in which the constituent glass panes and plastic glazing sheet material have not been formed or bent in the course of manufacture

2.9 curved laminated glass

laminated glass in which the constituent glass panes and plastic glazing sheet material have been deliberately shaped by forming or bending prior to laminating

2.10 interlayer

one or more layers of material acting as an adhesive and separator between plies of glass and/or plastic glazing sheet material

Note 1 to entry: The interlayer can also give additional performance to the finished product, for example impact resistance, resistance to fire, solar control and acoustic insulation.

Note 2 to entry: The interlayer itself can also encapsulate non-adhesive films and plates, wires, grids, etc.

2.11 encapsulated material

non-adhesive material that is encapsulated by an interlayer between the glass and/or plastic glazing materialNote 1 to entry: The non-adhesive material can be a film, plate, wire, grid, etc.

2.12 film

thin planar product of arbitrarily-limited maximum thickness in which the thickness is very small in proportion to length and width

Note 1 to entry: Film is generally supplied in roll form.

2.13 plate

smooth, flat piece of material of uniform limited thickness that may be perforated

2.14 grid

regular arrangement of wires

2.15 folio lamination process

lamination process where the interlayer is a solid film which is placed between the plies of glass or plastic glazing sheet material and is then subjected to heat and pressure to produce the final product

Note 1 to entry: The pressure can be higher or lower than the ambient pressure.

2.16 cast-in-place lamination process

lamination process where the interlayer is obtained by pouring a liquid between the plies of glass or plastic glazing sheet material and is then chemically or ultraviolet cured to produce the final product

Note 1 to entry: Lamination processes other than those defined in 2.15 and 2.16 are available, but they do not necessarily fit into either of the two methods defined in 2.15 and 2.16.

2.17 stock sizes

sizes which are intended to be recut or processed for final use

2.18 finished sizes

sizes which are either manufactured to size or cut from stock sizes and may be further processed

Note 1 to entry: Examples of further processing can include edge worked, drilled or face decorated.
