This Europea

29、n Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by June 2009, and conflicting national standards shall be withdrawn at the latest by June 2009. Attention is drawn to the possibility that some of the elements of

30、this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This standard is divided into parts: - Clauses 4 and 5: General questions; - Clauses 6 to 11: Applications to stairs made of solid wood. If a general sta

31、ndard on stairs is developed and adopted, Clauses 4 and 5 of this document will be reconsidered to be aligned with the general standard, if needed. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European

32、Standard: Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and the United King

34、fulfilment of mechanical resistance and stability characteristics are made of solid wood. These stairs are traditionally designed. NOTE 1 If the filling of the guarding does not contribute to the mechanical stability and resistance, the used material is not relevant. NOTE 2 Examples of traditionally

35、 made/designed stairs are given in Annex E. This European Standard covers: stairs either pre-assembled, partly pre-assembled or in component form including balustrades and handrails for internal or external use. This European Standard does not consider the contribution of these elements to the overa

36、ll structure design. The ability of a stair to contribute to the overall stability of the works or to the strength of the structure is not covered by this standard. Carpets on stairs are not covered by this Standard. The surfaces of the wooden elements may be exposed or covered by finishes. Where st

37、airs are supplied with a finish or covering, aesthetic or visual characteristics will not be covered by this Standard and references shall be made to the appropriate product standard (e.g. colour fastness of carpet finishes). 2 Normative references The following referenced documents are indispensabl
