This European Standard gives principles of glazing as well as recommendations on the selection of components, e. g. frame sections, beads, drainage holes, etc., for fitting glass into frames of any material. This European Standard applies to all basic types of edge supported vertical and sloping glazing systems, in all types of fixed or opening frames used in buildings. This European standard specifies also the functions, requirements and installation of glazing blocks within a frame during its manufacturing, transportation, installation and operational life. The standard applies to glazing blocks used for all types of flat or curved glass, as well as to derived processed types of glass. The observance of these recommendations will ensure a reasonable working life of the glazing. For certain glass products, e. g. fire resistant glazing, security glass, other or additional requirements, rules or recommendations may apply. Information with regards to the durability of a glass product is given in the applicable harmonised European Standard (hEN). Depending on the specific glass product, this will be referenced in the hEN in either clause 4.3. or clause 4.4. Within the clause, mention is also made of/to manufacturer's installation instructions and applicable standards. The standard is applicable to European climate conditions. This European Standard does not apply to the following: glass blocks and paver units (EN 1051-1) channel-shaped glass (EN 572-7) structural sealant glazing (see EN 13022 parts 1 and 2 and ETAG 002) adhesively bonded glazing in window point fixed glazing greenhouses (see EN 13031-1)
