Glass in building - Basic soda lime silicate glass products - Part 2: Float glass

This European Standard specifies dimensional and minimum quality requirements (in respect of optical and visual faults) for float glass, as defined in FprEN 572-1:2011, for use in building. This European Standard applies only to float glass supplied in jumbo sizes split sizes and oversize plates.

Glas im Bauwesen - Basiserzeugnisse aus Kalk-Natronsilicatglas - Teil 2: Floatglas

Diese Europäische Norm legt die Anforderungen an Maße und Mindestqualität (in Bezug auf optische und sichtbare Fehler) für Floatglas für das Bauwesen, wie es in FprEN 572 1:2011 definiert ist, fest.
Diese Europäische Norm ist nur für Floatglas, das in Bandmaßen (siehe Anmerkung 1), in geteilten Bandmaßen (siehe Anmerkung 2) und in übergroßen Scheiben (siehe Anmerkung 3) geliefert wird, anwendbar.
ANMERKUNG 1   Bandmaße — Jumbo sizes — PLF (Plateau Largeur de Fabrication).
ANMERKUNG 2   Geteilte Bandmaße — Split sizes — DLF (Dimension Largeur de Fabrication).
ANMERKUNG 3   Übergroße Scheiben — dabei handelt es sich um Scheiben mit der Nennlänge, H, größer als 6 000 mm. Bei diesen Scheiben handelt es sich um Sonderanfertigungen.
EN 572 8 informiert über Floatglas in anderen als in dieser Europäischen Norm aufgeführten Liefer  und Festmaßen.

Verre dans la construction - Produits de base : verre de silicate sodocalcique - Partie 2: Glace

La présente Norme européenne détermine les exigences dimensionnelles et les exigences qualitatives minimales (concernant les défauts optiques et les défauts d’aspect) s’appliquant à la glace flottée telle que définie dans le EN 572-1:2012, pour l’utilisation dans la construction.
La présente Norme européenne ne s’applique qu’à la glace flottée fournie en plateaux à largeur de fabrication (voir NOTE 1), en dimensions à largeur de fabrication (voir NOTE 2) et en plateaux grande longueur (voir NOTE 3).
NOTE 1   Jumbo sizes - PLF (plateau largeur de fabrication) - Bandmasse.
NOTE 2   Split sizes - DLF (dimension largeur de fabrication) - Geteilte Bandmasse.
NOTE 3   Plateaux grande longueur - Il s'agit de plateaux dont la longueur nominale, H, est supérieure à 6 000 mm. Ces plateaux font l'objet d'une commande spéciale.
L’EN 572-8 donne des informations sur les glaces flottées fournies dans des dimensions, c'est-à-dire des mesures livrées et des mesures découpées finales, autres que celles couvertes par la présente Norme européenne.

Steklo v gradbeništvu - Osnovni izdelki iz natrij-kalcijevega silikatnega stekla - 2. del: Ravno steklo

Ta evropski standard določa zahteve glede mer in minimalne kakovosti (v zvezi z optičnimi in vizualnimi napakami) za ravno steklo, kot je določeno v standardu FprEN 572-1:2011, za uporabo v gradbeništvu. Ta evropski standard se nanaša le na ravno steklo, dobavljeno v »jumbo« velikostih, razdeljenih ploščah in predimenzioniranih ploščah.

1 Scope
This European Standard specifies dimensional and minimum quality requirements (in respect of optical and
visual faults) for float glass, as defined in EN 572-1:2012, for use in building.
This European Standard applies only to float glass supplied in jumbo sizes (see Note 1), split sizes (see
Note 2) and oversize plates (see Note 3).
NOTE 1 Jumbo sizes — PLF (plateau largeur de fabrication) — Bandmasse.
NOTE 2 Split sizes — DLF (dimension largeur de fabrication) — Geteilte Bandmasse.
NOTE 3 Oversize plates – these are plates where the nominal length, H, is greater than 6 000 mm. These plates are
produced to special order.
EN 572-8 gives information on float glass in sizes (i.e. supplied and final cut sizes) other than those covered
by this European Standard.
