3.1 batch of glass panes
quantity of glass panes of the same nominal size and nominal thickness, produced in the same process under consistent controlled conditions
4 Material
Thermally toughened safety glass shall be manufactured of plate glass, either float or polished.
5 Finish
The finished glass pane shall meet the strength requirement of ISO 614. If the finishing method used on the glass pane lowers its strength below the strength required by ISO 614 for the untreated plate, either the finishing method needs to be changed or a thicker glass pane shall be used.
6.1.3 Other dimensions
Dimensions other than those listed in 6.1.1 and 6.1.2 may be agreed on between the parties concerned.
The thickness shall be calculated in accordance with Annex A.
6.2 Edges
All edge work shall be smooth ground and carried out before toughening the glass. See Figure 3.BS ISO 21005 pdf download.
