16、and cladding based on individual elements. EN 15146:2006 (E) 5 1 Scope This European Standard defines the characteristics of solid wood panelling and cladding without tongue and groove on edges, machined from the following most common European species of softwood: spruce/fir, pine, larch, European D
17、ouglas fir and maritime pine. Products are intended for interior or exterior use. Coatings and finishings are not dealt with in this European Standard.

For special purposes (for instance, acoustic) the edges may have fastening slots. The ends of the boards may be end matched 3.2 end matching any profile for connection at the
27、 end of the panelling or cladding including tongue and/or groove 3.3 panelling elements of solid wood mainly for interior use 3.4 cladding elements of solid wood mainly for exterior use 3.5 face visible surface of an element NOTE Includes edges and chamfer. 4 Symbols and abbreviations Symbols and ab
28、breviations used in this European Standard are given in Figure 1 and in Table 3 and Table 4. 5 Requirements 5.1 General The softwood species shall be selected with regard to the appearance expected, the suitability for the intended purpose and the general characteristics of the species itself. All r
29、equirements apply at the time of production unless the manufacturer states otherwise. 5.2 Appearance and finishing 5.2.1 General Grading applies to the face only, unless otherwise specified. Machining requirements are covered in 5.4.4 and apply to all grades of all species. Natural variation within
30、a single species is generally accepted as a common feature of wood and is not considered for classification of appearance, with the exception of free grade. Measuring features shall be in accordance with EN 1310. Concerning knots the general method in EN 1310:1997, 4.1.1, applies. The boards may be
31、finished with surface coating. The grading shall be done before coating.
