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.
