BS EN 14915:2013EN 14915:2013 (E) 5 1 Scope This European Standar
23、d defines and specifies the relevant characteristics and the appropriate test methods to determine these characteristics for solid wood products to be used as panelling and cladding (including siding) for: wall and ceiling panelling for internal use, wall and ceiling cladding for external uses. It p
24、rovides for the evaluation of conformity and the requirements for marking these products. This European Standard does not cover panels intended for use as stiffening elements. This European Standard does not cover suspended ceiling in wood panelling and cladding. This European Standard does not cove
25、r the processes for treatment, surface coating or modification. This European standard does not cover products which are produced from laminated layer section. This European Standard covers treated, untreated and surface coated products, including those made of thermally or chemically modified wood,
26、 as well as finger jointed and edge glued products. NOTE Prescriptions for surface coating and treatment can be found in documents valid in the place of use. This European Standard covers products in compliance with EN 14519, EN 15146 and EN 14951, and other solid timber products manufactured for us
27、e as panelling and cladding. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
