This European Standard specifies dimensional and minimum quality requirements (in respect of optical and visual faults) for basic soda-lime silicate glass products, as defined in EN 572‑1:2012 , for use in building. It applies to supplied sizes or cut sizes for final end use.
This European Standard does not apply to final cut sizes having a dimension less than 100 mm or a surface area less than 0,05 m 2.
This European Standard does not apply to float glass supplied as jumbo, split sizes or oversize plates nor to polished wired glass, drawn sheet glass, patterned glass, patterned wired glass supplied as stock sizes. For specifications regarding these types of glass, see EN 572‑2:2012 , EN 572‑3:2012 , EN 572‑4:2012 , EN 572‑5:2012 and EN 572‑6:2012 respectively.
This European Standard does not apply to final cut sizes of wired or unwired channel shaped glass For specifications on this type of glass, see EN 572‑7:2012 .
