Glass in building - Painted glass for internal use - Part 1: Requirements
This European Standard specifies minimum quality requirements (in respect of optical, visual and edge faults) and durability tests for painted glass for internal use in building.
This standard applies to testing of paints that can be used to produce painted glass. The test of durability are undertaken on soda lime silicate glass as being a representative substrate.
Painted glass, that conforms to this standard, may have substrate as follows: basic glass, special basic glass, chemically strengthened basic glass, thermally treated basic and special basic glass, laminated glass or laminated safety glass.
The painted glass may be translucent, transparent or opaque and supplied in stock/standard sizes and as-cut finished sizes.
NOTE 1 Artistic products are excluded from the scope of this standard.
For painted glass used in aggressive and/or constantly high humidity atmospheres, e.g. horse riding halls, swimming pools, medical baths, saunas, etc. this standard is not applicable.
NOTE 2 Bathrooms and kitchens are not considered as constantly high humidity atmospheres.
This standard does not give requirements for framing, fixing or other support systems.
NOTE 3 Useful advice on these items is contained in the informative annex C.

Das farbige Glas kann durchscheinend, durchsichtig oder opak sein sowie in Lager /Standardmaßen und in Festmaß-Zuschnitten geliefert werden.
ANMERKUNG 1 Künstlerische Produkte sind vom Anwendungsbereich dieser Norm ausgeschlossen.
Diese Norm gilt nicht für farbiges Glas, das in aggressivem Klima und/oder Atmosphären mit dauerhaft hoher Luftfeuchte, z. B. in Reithallen, Schwimmbädern, Heilbädern, Saunen usw., verwendet wird.
ANMERKUNG 2 Badezimmer und Küchen werden nicht als Atmosphären mit dauerhaft hoher Luftfeuchte angesehen.
Diese Norm gibt enthält keine Anforderungen für Rahmen-, Befestigungs- oder andere Halterungssysteme.

Le verre laqué peut être translucide, transparent ou opaque et livré suivant des mesures libres/standard ou des mesures fixes brutes de coupe.
NOTE 1 Les produits artistiques sont exclus du domaine d’application de la présente norme.
Pour le verre laqué utilisé dans des atmosphères agressives et/ou avec un taux d’humidité élevé en permanence, par exemple dans des manèges équestres, des piscines, des bains médicaux, des saunas, etc., la présente norme n’est pas applicable.
NOTE 2 Les salles de bain et les cuisines ne sont pas considérées comme des atmosphères avec un taux d’humidité élevé en permanence.

Steklo v gradbeništvu - Barvano steklo za notranjo uporabo - 1. del: Zahteve
Ta evropski standard določa zahteve glede minimalne kakovosti (v zvezi z optičnimi in vizualnimi napakami ter napakami robov) in preskuse vzdržljivosti za barvano steklo za notranjo uporabo v zgradbah. Ta standard se uporablja za preskušanje barv, ki se lahko uporabljajo za proizvodnjo barvanega stekla. Preskusi vzdržljivosti se izvajajo na natrij-kalcijevem silikatnem steklu, ki se smatra kot reprezentativna podlaga. Barvano steklo, ki je skladno s tem standardom, je lahko izdelano iz naslednjih podlag: osnovno steklo, posebno osnovno steklo, kemično ojačano osnovno steklo, toplotno obdelano osnovno in posebno osnovno steklo, lepljeno steklo ali lepljeno varnostno steklo. Barvno steklo je lahko prozorno, prosojno ali neprozorno ter se lahko dobavlja v standardnih velikostih/velikostih na zalogi ali v nestandardnih velikostih. OPOMBA 1: Področje uporabe tega standarda ne zajema umetniških izdelkov. Ta standard se ne uporablja za barvano steklo, ki se uporablja v agresivnih atmosferah ali atmosferah s konstantno visoko vlažnostjo npr. pokritih jahališčih, bazenih, medicinskih kopelih, savnah itd. OPOMBA 2: Kopalnice in kuhinje se ne obravnavajo kot atmosfere s konstantno visoko vlažnostjo. Ta standard ne podaja zahtev za uokvirjanje, pritrjevanje ali druge oblike podpornih sistemov. OPOMBA 3: Informativni dodatek C vsebuje uporabne nasvete glede teh točk.

FprEN 16477-1:2016 (E) 4 European foreword This document (FprEN 16477-1:2016) has been prepared by Technical Committee CEN/TC 129 “Glass in Building”, the secretariat of which is held by NBN. This document is currently submitted to the Unique Acceptance Procedure. kSIST FprEN 16477-1:2016
FprEN 16477-1:2016 (E) 5 1 Scope This European Standard specifies minimum quality requirements (in respect of optical, visual and edge faults) and durability tests for painted glass for internal use in building. This standard applies to testing of paints that can be used to produce painted glass. The test of durability are undertaken on soda lime silicate glass as being a representative substrate. Painted glass that conforms to this standard, may have substrate as follows: basic glass, special basic glass, chemically strengthened basic glass, thermally treated basic and special basic glass, laminated glass or laminated safety glass. The painted glass may be translucent, transparent or opaque and supplied in stock/standard sizes and as-cut finished sizes. NOTE 1 Artistic products are excluded from the scope of this standard. For painted glass used in aggressive and/or constantly high humidity atmospheres, e.g. horse riding halls, swimming pools, medical baths, saunas, etc. this standard is not applicable. NOTE 2 Bathrooms and kitchens are not considered as constantly high humidity atmospheres. This standard does not give requirements for framing, fixing or other support systems. NOTE 3 Useful advice on these items is contained in the informative Annex C. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

Continuously dry internal applications exclude bathrooms, shower cabinets, kitchens. 8 Testing of painted glass 8.1 Durability 8.1.1 General The durability of painted glass for internal use shall be determined by a number of tests, in accordance with the following specifications: — High humidity test (see Annex A: condensation water test); — High temperature test without water; — Radiation resistance test ISO 11341. 8.1.2 Test specimens The painted glass shall be cut to the specimen size of 100 mm x 100 mm and stored in ambient conditions at least 24 h before testing. Cutting oils shall not be used during cutting of the specimen. For each test, three samples shall be tested. Defaults present before testing shall be identified before ageing and shall not be taken into account in the assessment of the test. Colour values shall be evaluated on each sample of uniform paint claiming for class A following Annex B and recorded. Concerning the radiation resistance test, the glass thickness shall be the minimum thickness produced. If the test equipment does not allow this sample dimension, the test specimens may be cut to other dimensions providing that the area is not less than 10 000 mm2. The maximum allowable number of defects after test will be calculated proportionally to the real area of the sample tested. kSIST FprEN 16477-1:2016
