BS EN 17416:2021 pdf download.Glass in building Assessment of release of dangerous substances Determination of emissions into indoor air from glass products.
BS EN 17416 provides specific rules for flat glass products used in buildings to support the assessment of release of dangerous substances into indoor air.
BS EN 17416 aims at complementing the general rules established in EN 16516:2017+A1:2020, by providing additional detailed rules on technical aspects specific to the glass products.
BS EN 17416 provides specific rules for the assessment of the release on dangerous substances from glass products into indoor air of buildings in complement to the horizontal rules given in EN 16516.
BS EN 17416 addresses specifically products as mentioned in TC 129 Mandate – M135 Amendment 1 EN (2012), i.e. products covered by the following European Standards: EN 1036-2 and EN 16477-21. However, this document can also be applied to other glass products containing volatile organic compounds (VOC) such as: EN 1279-5. EN 15755-1 and EN 14449. Glass products that do not contain organic compounds are not in the scope of BS EN 17416 (see Annex A).
BS EN 17416 addresses the release of dangerous substances into indoor air from construction products, although it can also be applied to glass products used in other applications such as furniture.

4.1 Intended conditions of use and emission scenario
4.1.1 Product description
The glass that represent in general the main part of the glass product does not contain any VOC. Glass is manufactured in furnaces where the raw materials are melted at a temperature above 1 500 °C and therefore no organic compounds whatsoever are present within the glass itself. VOC in glass products are generally found in added components such as paint, plastic film, sealant, glue, etc. Moreover the organic containing component is rarely exposed directly to the indoor air but most likely placed against a hard surface (e.g. wall, ceiling, floor, frame, etc.).
4.1.2 Mirrors, painted glass, and adhesive backed polymeric filmed glass
Mirrors (EN 1036-1), painted glass (EN 16477-1), adhesive backed polymeric filmed glass (EN 15755-1):
the component that is susceptible to release VOC’s is applied on the back of the product on the entire surface; it consists of paint and/or adhesive polymeric film (see Figure 1). During use, the face covered is generally applied on to a hard surface such as a wall. Those products are used inside the building as decorative wall covering; they rarely cover all four walls of a room but more generally two walls or less.BS-EN-17416-2021
