This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsemen
17、t, at the latest by December 2016, and conflicting national standards shall be withdrawn at the latest by December 2016. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identify
18、ing any or all such patent rights. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association.

BS EN 12488:2016EN 12488:2016 (E) 5 Introduction This European Standard deals with the glazing system i.e. the glazing, the glazing blocks, the sealants, the gaskets and the components used to assemble the glazing into a fr
21、ame, as well as the rebate. It gives the basic principles to avoid damages due to the construction. The observance of these recommendations will ensure a reasonable working life of the glazing. Additional requirements and precisions are to be found in the national regulations and/or national codes o
22、f practice, in order to deal with regional particularities due to climate, professional habits, availability of materials, etc. Special requirements can also be specified by manufacturers of components of the glazing system, including glazing. Mechanical, thermal, chemical and moisture conditions ar
23、e essential to preserve the functionality and the operability of the glazing in the long term. Information with regards to the durability of a glass product is given in the applicable harmonized European Standard (hEN). BS EN 12488:2016EN 12488:2016 (E) 6 1 Scope This European Standard defines princ
24、iples of glazing as well as recommendations on the selection of components, e.g. frame sections, beads, drainage holes, etc., for fitting glazing 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 fix
25、ed 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 o
26、r curved glass, as well as to derived processed types of glass. For certain glass products, e.g. fire resistant glazing, security glass, other or additional requirements, rules or recommendations may apply. The standard is applicable to European climate conditions. This European Standard does not ap
27、ply to the following: glass blocks and glass pavers (EN 1051-1); channel-shaped glass (EN 572-7); structural sealant glazing (see EN 13022-1 and EN 13022-2 and ETAG 002); adhesively bonded glazing in window; point fixed glazing; greenhouses (see EN 13031-1). As this standard gives basic assembly pri
28、nciples only, national requirements, rules or recommendations may also apply. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
