This Part of this standard applies only to float glass supplied in jumbo sizes (see note 1) and split sizes (see note
2).
NOTE 1 Jumbo sizes — PLF (plateau largeur de fabrication) — Bandmasse.
NOTE 2 Split sizes — DLF (dimension largeur de fabrication) — Geteilte Bandmasse.
EN 572-8 gives information on float glass in sizes other than those covered by this Part.
