FprEN 14732:2014 (E) 5 Foreword This document (FprEN 14732:2014) has been prepared by Technical Committee CEN/TC 124 “Timber structures”, the secretariat of which is held by AFNOR. This document is currently submitted to the UAP procedure. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports basic work requirements of Regulation (EU) No. 305/2011. For relationship with EU Regulations, see informative Annex ZA which is an integral part of this document. NOTE Due to fact that the Framework Partnership Agreement between the Commission and CEN & CENELEC is not signed yet, there are currently no New Approach Consultants in place for 2014. Therefore the provisions of CEN-CENELEC Guide 15 cannot be met. This shall not prevent the processing of draft standards nor the offering of harmonized standards to the Commission. In particular, draft standards can be sent to vote without Consultant assessment. This note will be removed from the Foreword of the finalized publication. kSIST FprEN 14732:2014

The panels and/or boards are connected to the framing members by suitable structural adhesive bonding or by mechanical fixing. The elements may be insulated or uninsulated. The exterior faces of the elements may also be covered with insulation material. This European Standard covers glued and mechanically fixed wall elements with length of maximal 16,5 m, height of maximal 3,2 m and of unrestricted thickness. This European Standard covers mechanically fixed floor and roof elements with length of maximal 16,5 m and a thickness of maximal 1,0 m and a width of maximal 3,5 m. The mechanically fixed floor element may include additional bond lines to increase stiffness to enlarge resistance versus vibrations. This European Standard covers glued floor and roof elements with length of maximal 12,5 m and a load bearing cross-sectional thickness of maximal 0,35 m and a width of maximal 3,5 m. This European Standard identifies structural (3.1.4) and non-structural (3.1.3) components to be used in the elements. This European Standard also lays down provisions and Procedures for Assessment and Verification of Constancy of Performance of these elements. This European Standard applies to elements that may have openings, e.g. for windows, doors etc. It does not apply to the properties of incorporated doors or windows.
